**MTR Modernisation Train** (also known as **Modernised First Generation Passsenger Train**, **改良版第一代載客列車**, formerly named **Metro-Cammell Train**, **Metro-Cammell Train** is a Urban Lines DC commuter electric train owned by MTR Corporation, which was produced by Metro-Cammell  and GEC-Alsthom (later Alstom). The first batch of trains, together with the Modified Initial System, entered service in 1979 and is the oldest train of the MTR Urban Lines. As of

MTR spent HK$1 billion in August 1998 to launch "**都城佳木车车设计计划**", commissioned by Australian company United Goninan Limited. Modernisation works were carried out for this model train and were completed in September 2001. The fully remodeled train is also known as "**Modernisation Train**" (**Modernisation Train**, M-Train for short). By the beginning of the 21st century, 12 of them were modified again and became special trains for Disneyland Resort Line.

This train model is currently running on Kwun Tong Line, Tsuen Wan Line, Island Line, Tseung Kwan O Line and Disneyland Resort Line, among which the first generation of trains have been running since 1979 (43 years old), the second-generation trains are at least 33 to 40 years old, and the third-generation trains are at least 25 years old; they are expected to be retired from 2022 to 2027.  They will be replaced by the CRRC Qingdao Sifang EMU, leaving the three sets for the Disneyland Resort Line in operation.

## History

### Modified Initial System and opening of the Tsuen Wan Line

In the 1970s, the revision of the early system was approved to be built. It was estimated in the design that the entire system would eventually run with 8-car trains, so the platforms of the entire line were reserved for 8-car trains. For this reason, in 1976, train manufacturers were invited to bid for a total of 140 cars. For this order of the M-Train cars (later CM-Stock),on July 5, Metro Cammell won the tender at the price of 350 million HKD , and then in March 10, 1978 purchased 70 more train cars to expand the fleet by 6 trains ; Since Kowloon Bay Depot was not completed at that time, some trains were assembled in the Kowloon-Canton Railway Hung Hom Freight Yard. Coincidentally, some of the standard-gauge Metro-Cammell EMU sets owned by the Kowloon-Canton Railway were assembled at Kowloon Bay Depot as both rail operating companies were owned by the Hong Kong Government.

The first trains were tested on the tracks of the Tyne and Wear Metro ahead of their journey to Hong Kong as 2-car sets. Then the train, on May 16, 1978 arrived in Hong Kong, and began testing at the Kowloon Bay Depot on September 4 of the same year.

The Modified Initial System used 4 cars (A-C+C-A) at the beginning of service, and increase to cars (B/C) when the whole line is open to traffic -C+B-C+C-A), so the 35 first-generation trains purchased by MTR for Template:Modified early system only have three sets of power cars. With the increase of passenger volume, the subway began to use 6-car trains in 1980April 28, and officially carried passengers on the next day; In the same year, all trains were driven by 6 trucks. In order to cooperate with the opening of Tsuen Wan Line, the subway began to use 8-car trains on October 9, 1981.

MTR purchased another 170 2A-generation T-Stock (later CT-Stock) from Metro Cammell on February 5, 1979 in preparation for the opening of the Tsuen Wan Line in 1982. This batch of cars was introduced in two batches. In addition to the power carriages, motor cars were also purchased at that time. The MTR classified these cards as D cards, and gradually increased each set to the current limit of 8 cars. During the transition period, there were also trains running with 7 cars. The Tsuen Wan Line was operated on September 6 in 1982 with 8-car trains on the whole line to meet the passenger demand, especially with many tsudents travelling at the start of the 1982-1983 school year.

In response to the continuous increase in the passenger volume of the Kowloon-Canton Railway, which indirectly increased the number of passengers transferring to the underground railway at Kowloon Tong Station, MTRCL purchased 18 additional trains in November 1983.

### Island Line, opening of Eastern Harbour Crossing and signal system upgrade

With the the opening of Island Line, MTR bid for 2B generation trains from the Metro Cammell in 1981, and Metro Cammell also won the car card contract, supplying a total of 128 2B generation I-Stock car cards. Subsequently, in 1985, the subway purchased 53 additional cars, of which 28 cars were used to expand Kwun Tong Line to 8 cars; and the other 25 cars were used to deal with1989 Increase in passenger capacity.

Until April 7, 1986, in response to the completion of Island Line Central Station and Sheung Wan Station on May 23 and passenger demand , especially for the passenger volume of Kowloon Tong Station, all trains on Kwun Tong Line officially operate with 8 cars per train (A-C+D+B-C+D+C-A). And from Island Line, eight-car trains were transferred, and seven-car trains were used for a time until the new cars arrived in Hong Kong.

In order to cooperate with the opening of Kwun Tong Line Eastern Harbour Tunnel in 1989, MTR purchased a total of 33 additional 2C G-Stock cards in 1985. Ducheng Jiamu has been acquired by the British General Electric-Alstom (referred to as Alstom), some of the trucks are manufactured by Alstom, and the traction system of the train has adopted its own GEC GTO Chopper before leaving the factory. Since only the 2C generation trains used the GEC GTO Chopper at that time, in order to facilitate maintenance, all 2C generation trains used the Island Line in the early days.

In order to increase the passenger capacity during peak hours and improve the service level during non-peak hours, and to respond to passenger complaints about train overcrowding, MTR invited train manufacturers to bid for the manufacture of a total of 88 trains in 1992-1993. Known as the H-Stock cars, MTR announced on March 5 that Alstom won the contract for the supply of 64 cars, including 48 power cars and 16 trailer cars. In addition, there is an option arrangement attached to the contract, which enables the company to purchase an additional 3 sets of 24 cars during the contract period; and the specifications of this batch of trains are compatible with those of the previous batch of trains, and the same maintenance equipment can also be deployed and used, and new energy-saving chopper and motor control instruments are installed.

MTR planned to replace machinery and equipment in 1991 in the next 5 years, one of which was to replace the traction system of the 1st and 2A generation trains from Cam Shaft to GEC GTO Chopper (same as 2C and 3rd generation trains), To save electricity and reduce maintenance costs , the 2C generation trains were mixed with the 1st and 2A generation trains and allocated to different routes: the last train to replace the lead system was completed in January 1995. The 2B generation trains continue to use the Mitsubishi RCT Chopper. Because the two traction systems operate differently, the 2B generation trains are relatively quiet.

### Train Modernisation

By 1997, the age of the first-generation trains was close to half of the design life, and MTR began to completely refurbish all M-Trains in August 1998. The project was undertaken by the Australian United Goninan Group. Afterwards, the contract was renewed to be responsible for the maintenance of the 2C and 3rd generation of this series of cars.

The works include improving the air-conditioning and ventilation system, lighting, recessed seats, multi-purpose space for wheelchairs and luggage, new hanging handrails, cab and car wiring resurfacing, etc. It also involves modifying the front components, refurbishing the interior and moving parts, automatic information display system, train status information system (Train Information System, TIS) and electronic voice announcement system (DVA for short). The information system in the cab of the train has also been improved to monitor multiple systems in the train. In the event of an accident, the system can provide immediate instructions to the train captain. Details are as follows:

car:
* Improved air conditioning and ventilation systems in the cabin
* Increase wheelchair space and related handrails
* Replace outdated lighting fixtures with low power consumption lighting fixtures
* New Ceiling (Includes: Paneling, Lighting and Ceiling )
* Concave non-slip stainless steel seat
* New non-slip floor
* Channels and walls replaced with new paneling
* New handrails – added color and repositioned to improve foot traffic
* Passenger Information System – Flashing Route Map and Electronic Display Screen
* Relaying of carriage lines

cab:
* Emergency Escape Doors and Pedals – Improved Operation and Ease of Use
* Closed-circuit television in the car – so that the captain can still monitor the situation of the platform in the cab
* New cab and driving console design to improve train operation and working environment
* Improve the train information system to monitor multiple systems in the train; when a train accident occurs, the system will provide immediate instructions to the train captain to deal with the accident
* Improved air conditioning and ventilation in the cab
* Resurface the cab wiring

The first refurbished train was put back into service on 21 December, 1998, and the entire project was completed in August 2001. The first 19 refurbished trains were not equipped with modern equipment (such as flashing route map and electronic display screen) until later. The pneumatic doors of all trains have been retained after the renovation and have not been changed to electric doors.

In addition, some train formations have changed their routes. The details are as follows. Among them, A115 was changed to Kwun Tong Line reserve car, replacing the original Island Line reserve (ie A145):

 Tsuen Wan Line | A117/A120, A141/A182, A151/A152, A153/A126, A159/A198, A171/A286, A173/A122, A181/A136, A201/A268, A205/A208, A207/A134, A209/A160, A 211 /A150, A217/A214, A219/A196, A285/A102, A287/A266, A289/A218

### Tseung Kwan O Line and Disneyland Resort Line open to traffic

Tseung Kwan O Line opened to traffic in 2002, because the newly purchased Korean-made trains could not immediately adapt to the two sets of new and old trains signaling systems, and the contractor responsible for the operation of the Tseung Kwan O Line Depot, United Goninan had no experiencing in repairing the Rotem stock. In order to ensure that Tseung Kwan O Line can be opened to traffic as scheduled, MTRCL decided to arrange the K-Train sets allocated to the Urban Lines to run on Kwun Tong Line. At the same time, MTR reorganized the arrangement of the British trains, and transferred 15 2C or 3rd generation British trains to Tseung Kwan O Line.

In order to cooperate with the opening of Disneyland Resort Line on August 1, 2005, MTR converted H-stock Alstom cars A/C274, A/C281, A/C284, A/C289, A/C291 and B/C490 from 2002 December to 2005 into three 4-car trains, becoming sets P501-506 for driverless service. For this conversion, more comfortable seats were installed, with extra Disney theming such as statues of famous characters, Mickey-shaped straphangers and passenger windows are in the shape of Mickey Mouse's head. In addition, the no. 2 and no.4 doors on each side of each car have been removed to increase seating capacity. Car B490 was lengthened with a new cab installed. The cab design was also modified on the outside, known by railfans as the "mouse head train." Despite the trains being intended to operate automatically, they still retain the driver's cab, which can be viewed from the passenger compartment at most times. These trains are also the only ones in the MTR system that do not use run numbers when operating.

The pneumatic doors were replaced with electric doors produced by ULTIMATE in Europe. Because of their similarities with the Urban Lines stock, these trains had to be returned to Kowloon Bay Depot by Siu Ho Wan Depot for repairs and overhaul. Like their Urban Lines counterpart, refurbishment and conversion of the DRL stock was done by United Goninan.

### Compartment improvement and relocation

In 2000, Shek Kip Mei Station, a blind person accidentally fell onto the rails through a connection gap about one meter wide between carriages. In order to prevent similar incidents from happening, MTR added three iron chains to the bellows between the coaches of all British trains; all orders since then have had this change, including the Hyundai Rotem K-stock and CNR/CRRC EMUs.

From May 10, 2008, the MTR experiment added 3 sets of small multi-purpose space in the 4th and 5th carriages of 3 trains in Island Line. In order to improve the passenger capacity and facilitate the boarding of passengers who use wheelchairs, baby strollers or luggage, nine seats will be removed from carriages 3-6 of all Island Line trains from August 2010, and two seats will be installed. A large multi-purpose space (a row of 6-seat seats was directly removed, and the original 3-seat seats and small multi-purpose space were expanded into a large multi-purpose space), and the new large multi-purpose space, as well as the original Half-seats are provided in the small multi-purpose spaces located in cards 1, 2, 7, and 8. The small multi-purpose spaces of trains No. 1, No. 2, No. 7 and No. 8 of Kwun Tong Line and Tsuen Wan Line trains also added half-seats successively in the second half of the same year.

From April 2011 onwards, six seats will be removed from carriages 2-7 of all Kwun Tong Line and Tsuen Wan Line trains, and a large multi-purpose space will be added. There is only one armrest in the space, and no half seats are installed. In July 2011, MTR successively removed the half-seats in the small multi-purpose spaces of trains No. 1, No. 2, No. 7 and No. 8 of Kwun Tong Line and Tsuen Wan Line. In mid-September 2011, the Island Line train removed a row of 6-seat seats on the 2nd and 7th decks to add a large multi-purpose space, while the 3rd-6th decks were originally large multi-purpose spaces with small multi-purpose spaces. The purpose space was restored to the original specification, and the number of large multi-purpose spaces in the four-car compartment was reduced to one. And all multi-purpose spaces no longer have half seating.

In August 2008, MTR put 3M stickers on the A105/A158 set to reduce the number of acid washes on the body, but in 2009 the train body no longer had the 3M stickers and painted gray. At present, the train has been reorganized into A105/A142 and A157/A158 (then A105/A142 was reorganized into A105/A182, A105/A146, A105/A236, A105/A140, A105/A132). For set A223/A236, cars B/C266 were replaced with B/C410, so there are two color cuts.

In April 2010, in response to the withdrawal of Tseung Kwan O Depot outsourcer United Goninan Australia and the adjustment of the signaling system, Tseung Kwan O Line British trains and Kwun Tong Line K-Trains were reversed to improve the noise problem of Tseung Kwan O Line (the body of this batch of trains has rust, so the MTR has carried out body acid washing work shortly after being transferred to Kwun Tong Line) . In view of the fact that Tseung Kwan O Line needs to use 16 trains, and there are only 13 K-Train EMUs, so the Tseung Kwan O Line will still transfer at least 3 M-trains from the Kwun Tong Line.

The installation of platform safety gates at all Urban Lines stations without them were completed at the end of 2011, and the MTR gradually removed the red iron chains at the connection points of the trains.

In 2011, MTR introduced European technology to install a silent air cushion on the door of a British-made train (A199/A176). The air cushion will automatically inflate to block the door gap and block the sound from entering the compartment. After the test, it is confirmed that the noise of the carriages of this train has been significantly improved, and the effect is good. The tests were subsequently extended to the A177/A220 and A217/A184 formations in December 2012 and mid-January 2013, respectively. Since June 2017, these 3 trains have stopped using silent air cushions. The air cushion of the group A177/A220 was removed during the overhaul, leaving only the metal frame.

In response to CNR C-Trains being put on Kwun Tong Line, some Kwun Tong Line M-trains have been transferred to other routes, to increase frequency and supplement service for the West Island extension of the Island Line in 2015:

 March to September 2013
 August to December 2014

### Plan to be refurbished again, but finally fell through/Withdrawal

More Info: **Rail Gen 2.0**
In July 2013, MTR issued an invitation to prequalify for the refurbishment of all 93 M-Trains in use on the Urban Lines. According to the invitation, the scope of refurbishment includes the front, body, cabin interior, floor, passenger information system, seats, lighting, advertising panels, changing the flashing route map to a dynamic route map, electronic information display system, installing CCTV, smoke detection interface for communication-based train control systems (CBTC) and other related projects .

In October 2014, MTR issued a prequalification invitation for the replacement of 78 trains of this type, and later stated to the media: "Purchase New cars will be more cost-effective than refurbished trains”, and the remaining 15 trains have not yet decided whether to refurbish or phase out.

At the same time, the MTR found that the "'*Door slots*" (**Door bottom guide**) at the bottom of the doors of these trains was easily struck by foreign objects such as coins and batteries, making the doors inaccessible. Smooth switching; in 2014, there were 88 related service delays, and even the entire train had to be returned to the depot for maintenance. In July, MTR decided to improve the design of the door guidance system in batches to reduce the chance of foreign objects obstructing the operation of the doors, so as to avoid the train having to stay on the platform for a longer time due to re-opening the doors or cause a train to be taken out of service.

On July 22, 2015, MTR issued a press release announcing the award of the the tender for 93 new train sets, as the comprehensive replacement of this type (except for Disneyland Resort Line trains), and is expected to arrive in Hong Kong successively from 2018 to 2023. The tender process for refurbished trains was subsequently terminated. As a result, P/Q501-506 will be the oldest train sets in the MTR system once their Urban Lines counterpart have retired.

At the beginning of November, MTR publicly awarded the tender for the Q-Train (contract number: Q056556), which would be 93 train sets and 6 backup cars. Among them, 128 cars may need to be temporarily stored in a place provided by the MTR before being shipped to Hong Kong. The retirement period of the M-Train was expected to be from late 2019 to 2024.

### Replacement of signaling equipment and testing new features

New Train will be put into service after New Signal System is activated. Therefore, 36 of the modernized trains have been installed with new signaling system related equipment to facilitate operation during the handover period of new and old trains. Some trains are also experimenting with installing new equipment, including soft rubber rings and olive-shaped handrails.

The following is the transfer of trains due to the replacement of the SACEM system with Thales CBTC from July 2016. Trains transferred to the Tsuen Wan Line will be equipped with new signal equipment (except A105/A132 and A191/A182), some trains have also been reversed (see below for details):

### Trains are being decommissioned one after another

In the early morning of September 11, 2022, train A167/A168 was assembled, consisting of retired cars and sent to Siu Ho Wan Depot for decommissioning. However, cars that were used solely for parts were retired first.

Since the first batch of CRRC Q-Trains were all arranged to run on the Kwun Tong Line, there was a shortage of available train sets for the Tsuen Wan Line and Island Line. Kwun Tong Line M-Trains would change their routes as temporary replacements to avoid the shortage of Tsuen Wan Line and Island Line (see below for details) and remain in service:

 April 2020
 End of December 2022
 Mid-February 2023
 End of March 2023
 April 2023

## Train Batch

* A/C112 and A/C126 are reserved sets, stored in Siu Ho Wan Depot; D745 and D783 are also reserved cars, stored in Tsuen Wan Depot and Kowloon Bay Depot respectively. Some useful parts (e.g. air conditioner, braking system, etc.) of the spare coaches have been removed for use by other trucks, and they can no longer be used.
* The B1 door of coach A126 has been disassembled for use by the B1 door of coach A153, although that car has also been scrapped.
* A/C115, A/C145, A/C273 and B/C404 and used to be a backup cars.
* B/C459 was decommissioned in 2008 due to the shortage of 2B generation parts, A/C131, B/C451 and D652 have been separated due to trains at Central Station in 2019 A/C255 was scrapped due to a collision accident; A/C255 was seriously damaged in 2019 due to the Lai King derailment, and it was scrapped due to the need to avoid the shortage of 2B generation parts . The above-mentioned trucks were disassembled between 2020 and 2021; and even if B/C445 and D736 were not seriously damaged due to  Lai King Station Train Derailment Accident, they have been in It will be disassembled in August 2022; as for the B/C493, D737, and D784 trucks that have been idle for many years, they will also be dismantled in August 2022.
* A/C291, A/C284, A/C289, A/C274, A/C281, B/C490 have been dedicated to the Disneyland Resort Line, and the serial numbers have been changed to P/Q501-506 respectively.

## Vehicle number and grouping

### Urban Lines Train Consists

The urban line trains are consisted of 8 cars, and the formation method is A-C+D+B-C+D+C-A, and A-C , B-C, and C-A are permanently coupled together. D cars are individual and can be separated if needed; however for A/C and B/C cars, they cannot be decoupled from each other and must be coupled/decoupled as groups.

Trains are designed to allow 4, 6 and 8-card formations:

* 4 cars (4M): A-C+C-A
* 6 cars (6M): A-C+B-C+C-A
* 8 cars (6M2T): A-C+D+B-C+D+C-A
* 8 cars, all motor cars (8M): A-C+B-C+B-C+C-A

However, there have also been 7-card formations in history. Although it is actually feasible, the design of this formation was not expected:

* 7 car (6M1T): A-C+B-C+D+C-A or A-C+D+B-C+C-A

#### Kwun Tong Line and Tseung Kwan O Line

Kwun Tong Line and Tseung Kwan O Line have a total of 15 M-Trains in service, of which 9-13 trains run on Kwun Tong Line, and the remaining 2-6 trains run on {{Tseung Kwan O Line} }} Walking, the daily dispatch of cars is uncertain.

## Events

### Kwun Tong Line

* On October 1, 1979, the modified Initial System (section from Shek Kip Mei to Kwun Tong) opened to traffic. Set A119/A120 was the first train to enter revenue service. At that time, the formation was A119-C719-C720-A120. The first-generation cars with the original number C7XX was later reorganized into C1XX, that is, the same number as the A car. (Example: A119-C719 was later changed to A119-C119, and so on) These cars are currently used on one train each of Island Line and Tsuen Wan Line respectively.
* On September 18, 2000, a blind person accidentally fell through the platform gap at Shek Kip Mei Station, and fell onto the tracks after mistaking the inter-car gangway as a door. The blind person suffered only minor injuries. In order to prevent similar incidents from happening, the MTR has added three iron chains to the outside of inter-car gangways so people would know not to board there at stations without platform safety barriers. These chains were removed when all Urban Line stations without these features had platform gates installed.
* On August 19, 2001, all non-refurbished M-Trains were removed from service for refurbishment.

### Tsuen Wan Line

* On April 27, 1993, MTR had the first derailment accident. A train (A111/A166 ) arrived at Mong Kok (then called Argyle), the connector between two cars was loosened on the way, with the last three cars decoupling and losing power, stopping in the tunnel. Unaware that the train was now only 5 cars long, the operator continued to bring the train into Argyle Station. Only after the platform staff notified him did he know that there was an accident, and no one was injured.
* On the evening of August 31, 2001, a train captain was driving a train bound for Central (A119/A116), in the downbound cab between Tsuen Wan Station and Tai Wo Hau Station, and was able to control until the train entered Tai Wo Hau Station and other staff found that he had passed out. Later, other staff drove the train into Kwai Hing Station and sent the train captain to hospital, where the train captain later died. This is the first fatal accident of a train captain since the opening of the MTR. In order to prevent similar incidents from happening, all MTR staff, especially those operating vehicles, are required to have a physical examination every year.

* On January 5, 2004, near 9:00 in the morning, a train bound for Central (A167/A140 ), while going to Admiralty Station, a 65-year-old man set fire on (A167), causing 14 people to be slightly injured. It was the first case of arson since the MTR system was opened.

See also: 2017 MTR arson case
* On February 10, 2017, at around 7:00 p.m., a train bound for Tsuen Wan (A113/A192 ), while going to Tsim Sha Tsui Station, was set on fire by passengers, causing thick smoke in the carriage, and 19 passengers in the carriage were burned by the fire; the arsonist was seriously injured later die.
* In the early morning of February 24, 2018, a train (A203/A110 ) was dispatched to Siu Ho Wan Depot conducted a train decommissioning exercise and returned to Tsuen Wan Line in the early morning of February 25, 2018; this test is the first time that an urban line train is not due to modification or disembarkation to go to [[Siu Ho Wan Line] Haowan Depot]].

See also: 2019 Tsuen Wan Line train collision accident
* In the early morning of March 18, 2019, train (A187/A112) collided with another train (A131/A218) during testing of the new CBTC signal system near Central Station, leaving both operators injured. Among them, the glass of the front cab of A131 was damaged, the car was tilted to the left and derailed, causing the connection between it and C131 to be distorted. In the 3rd to 4th cars (D652 and C451) of the other set, the car body was dented, the doors were sheared off, and the seats and armrests in the car were knocked out of place. Affected by the accident, the service between Tsuen Wan Line between Admiralty Station and Central Station was suspended for 2 days; this accident is the first collision since the opening of MTR. After the investigation is completed, the relevant train has been reorganized into A131/A112 and A187/A218. The former was scrapped afterwards, and cars A/C112 of the train involved in the accident were sent to Siu Ho Wan Depot as a backup car, while the latter was put into service again on December 4.

* On October 6, 2019, at about 5:50 pm, a train bound for Mei Foo (A255/A126) entered the siding between Lai King and Mei Foo. After entering the siding, the train hit the buffer stop. The track is usually not used. When the train passed the position at a slow speed of about 10 kilometers per hour, it touched the concrete buffer beside the track, but the train wheels did not deviate from the track. 6 passengers and 2 MTR staff were injured in the accident, and about 1,000 people were evacuated. It was also the second accident after the Tsuen Wan Line crash on March 18 of the same year. After the investigation was completed, the involved carriage (A/C255) was scrapped on January 17, 2021. It was the first train of the same type to be decommissioned.
* November 13, 2022: At 9:50 am, a Tsuen Wan Line train (A285/A280) derailed at Yau Ma Tei Station, causing at least two sets of doors to break off. Due to this, service was suspended between Lai King and Jordan, with shuttle buses running between the two stations, with service on unaffected sections reduced to 6 minute headways until the train was removed and an inspection of the tracks was completed.

### Island Line

* On December 21, 1998, the first refurbished train (A251/A180) was the first revenue service train on the Island Line.
* On August 10, 1999, a train captain prepared to change directions in a train (A273/A186) when it hit the buffer stops at the end of the tracks, causing head injuries to the train operator.
* On December 28, 2014, at 6:00 am, the West Island Line was partially opened for revenue service (Hong Kong University Station and Kennedy Town Station opened). Train (A131/A218 and A107/A154) is arranged as the first train to service the line, and the first train departs from Kennedy Town Station and Chai Wan Station respectively.
* On March 29, 2015, Sai Ying Pun Station opened. Train (A181/A136 and A137/A162) is arranged as the first train to serve, and the first train is respectively operated by Kennedy Town Station and Chai Wan Station. Prior to the station opening with the extension in service, trains would still stop at Sai Ying Pun but doors would not open, with the platform doors covered.
* On October 26, 2017, at 1 am, a train (A159/A252 ) was driving back to the designated berth in Chai Wan Depot, the underbody airbag of one of the coaches (D636) overinflated. The problem caused one wheel to deviate from the track, the car collided with the track and the equipment beside the track, and broke a ladder used for inspections by staff. The body of the car involved was damaged, and the debris of the stairs also scratched another train . The incident resulted in 4 Island Line trains (A101/A166, A159/A252 , A183/A206 and A193/A242) getting stuck inside Chai Wan Depot and unable to enter service. MTR had to temporarily transfer four trains from Tsuen Wan Depot, Kowloon Bay Depot andTseung Kwan O Depot to the Island Line while the depot access track was closed.
* On November 20, 2019, near 6:07 in the evening, a train bound for Kennedy Town (A103/A170 ), when driving to Wan Chai Station, a passenger accidentally stepped on the gap at the position 8-2 of platform 2, resulting in being trapped at Wan Chai Station. About ten minutes from platform No. After the accident was dealt with, the relevant train drove to Admiralty without passengers and then returned to the depot for inspection. During this period, the B4 door of the B404 car card (the fourth door on the left of the fourth car at the time of the incident) was the place where the accident occurred. The door did not close properly and needs to be driven slowly.
* On December 2, 2021, at around 6:00 pm, a train (A153/A160) towards Kennedy Town was approaching Causeway Bay Station, and car A153's B1 door (the first door on the left of the first card at the time of the incident) was hit by a loose advertising board and flew off, then fell down the track. No one was injured. Affected by the incident, train services between Wan Chai Station and Quarry Bay Station were suspended.

### Tseung Kwan O Line

* On August 18, 2002, at 3:00 pm, Tseung Kwan O Line was fully opened to traffic; train (A269/A288  and A287/A266 ) is arranged as the first train, the first train departs from Po Lam Station and North Point Station respectively.
* July 26, 2009, LOHAS Park opened; train (A267/A286 and A285/A280) is arranged as the first train to enter service at this station, with the latter respectively as the first train from Tiu Keng Leng to LOHAS Park.

### Others

* On April 2, 2021, the B459/C459 backup cars that had been placed in Siu Ho Wan Depot for a long time was cut into two sections by engineering personnel and transported away by truck for scrap.
* In August 2022, the B493/C493, D737 and D784 backup cars that have been placed in Siu Ho Wan Depot for a long time, and the 2019 Tsuen Wan Line train derailment accident at Lai King Station were sent to [ The B445/C445 and D736 spare cars of [Siu Ho Wan Depot]] were sawed into two sections by the engineers and transported away by trucks.

### Significance in Hong Kong Politics

* The car number of one of the D-cars of this train is D689, because the number of the card has the meaning of insulting the former chief executive Leung Chun-ying (689 is the number of votes Leung was elected chief executive), so it aroused discussion among netizens ; but similarly, one of the D cards has the card number D777, because the car number also has the meaning of insulting the former Chief Executive Carrie Lam (777 is the number of votes for Carrie Lam to be elected Chief Executive).

## Daily Operational Issues

The 1st generation and 2A generation trains have been in service for more than 40 years, and the 2B generation and 2C generation trains are also at least 33 to 37 years old. Despite being refurbished and extended life for about 10 to 15 years, but the aging of the train paint surface is becoming more and more obvious, such as increased traffic noise, aging interior (partial paint is discolored), train wheels make "deaf" noises like steam trains, breakdowns Frequently, some members also hoped that the MTR would replace the new trains as soon as possible due to the noise problem. However, since most of the trains are not independently organized, and the MTR planned to use this type of train for at least 50 years earlier than when the early system was revised, the replacement train plan was not planned at that time. Therefore, this necessitated MTR to either refurbish the trains a second time or replace them with new trains, where they went with the latter in 2017.

Since the design of this type of train was based on the London Underground and "Tyne and Wear" subway trains of the same period at the time, air-conditioning equipment was added in consideration of Hong Kong's climate environment during the design, but its power is limited, so it needs to be installed in the door inserts. There are some gaps between the body for ventilation. However, these gaps allow the noise outside the train to be transmitted into the compartment when the train is running. In addition, since the bodywork is designed in the 1970s, and the sound insulation measures of the train are seriously insufficient (except for A177/A220, A199/A176 and A217/A184). In addition, the bogie suspension is of an older design, so it will make a loud noise when in operation. When entering the station on ordinary underground and elevated platforms, the noise often exceeds 90 decibels, and the noise on the elevated section(s) exceeds 100 decibels. Many passengers have complained about the noise generated by the trainsets and it has also become a concern in Legislative Council meetings.

During the 8-year transition period (2002 to 2010) before Tseung Kwan O Line was switched to the K-Train EMUs, councilors have complained numerous times about the serious noise problem of Tseung Kwan O Line (Especially on the section from Tiu Keng Leng to Yau Tong). The MTR only explained the reason for the wide tunnel and the curved route, but did not really explain the Tseung Kwan O Line to the members The Depot was outsourced to United Goninan (the company responsible for refurbishing the M-Trains), but the company did not know how to maintain Korean-made trains, and the Korean-made trains cannot adapt to the two new sets immediately.

In recent years, there have been complaints about the Tsuen Wan Line's serious noise problems from Tsuen Wan Station to Mei Foo Station and Kwai Hing Station to Tai Wo Hau Station. MTR stated they had strengthened the polishing of the rails and installed wheel rings and noise-reducing liquid bottles commonly known as "silencers" on the wheels (this bottle will apply liquid to the wheels when the train is running to reduce friction with the rails). However, the noise level continued to exceed 80 decibels . Although the effect is not great, but at least there is an improvement.

Island Line has also been complained by citizens that a quarter of the stations have serious railway noise problems, and the noise in the carriages exceeds 90 decibels, and when the train passed through the tunnel between Tai Koo Station and Quarry Bay Station, the noise reached 97 decibels, which affected the hearing of passengers. In addition, Kwun Tong Line has also been complained by citizens. When Metro Cammell sets passed through the tunnel from Yau Tong Station to Lam Tin Station, due to the sharp curve and the train going downhill, the noise also reached 92.6 decibels, the situation is cause for concern.

Due to the high age of this model, and the cost-effectiveness of refurbishing trains is not as high as buying new trains, MTR Corporation purchased 93 8-car trains from Qingdao Sifang Locomotive and Rolling Stock Co., Ltd., a subsidiary of CRRC to replace the Metro Cammell and Alstom sets used on the Urban Lines.
