IKK Trains Reformation Works

**IKK Trains Reformation Works (近畿川崎列車重編工程)** refers to the integration of Tuen Ma Line with 8-car trains, and East Rail Line, West Rail Line and Ma On Shan Line original 12-car, 7-car and 4-car IKK trains are reorganized into standardized 8-car trains.

## Background

More Info: **Rail Gen 2.0** After completion of the section from Hung Hom to Tai Wai, West Rail Line and Ma On Shan Line will be merged together with the new section into the Tuen Ma Line, and uniformly run on trains composed of 8 cars. At the same time, SP1900s belonging to the East Rail Line will also be transferred to Tuen Ma Line. Therefore, the MTR awarded a contract to the "Itochu-Kinki-Kawasaki Corporation" to purchase 36 intermediate cars for expansion, and refit the 348 cars of the original three orders, so as to expand the existing trains of the West Rail Line and Ma On Shan Line to 8 cars. In addition, 17 new trains were ordered from CRRC.

The reorganization project is mainly carried out at Pat Heung Depot, and the East Rail Line first-class coaches will be transported back to the Kinki Kawasaki Factory in Hyogo Prefecture, Japan for refurbishment, after refitting, were shipped from Kobe, Japan to Hong Kong . All newly-purchased carriages and refurbished carriages are equipped with LCD screens on the top of the doors and gangway connections, which respectively play Dynamic Route Map and station information, and the air-conditioning system is also equipped with smoke sensors. In addition, MTR awarded a contract in February 2016 to replace the original MTR In-Train TV 15-inch display with a 19-inch 16:10 or 19-inch 4:3 display, however, the relevant works are basically carried out in parallel with the carriage modification works.

However, during the reformation works, the Japanese manufacturer, ITOCHU-Kawasaki-Kinki Sharyo, found that the roof on many of the train sets was distorted to varying degrees, so maintenance work was carried out at the same time during the refitting project. Some carriages with serious distortions were decommissioned during the reorganization project to supply parts for other carriages.

West Rail Line: The first 8-car train (D357/D358) will be tested without passengers during the daytime from 2015 November 28, and will be tested in 2016[ [January 2]] officially put into service. However, the train carried passengers for less than 5 hours that day, and because of SelTrac trip computer failure, it had to be taken out of service and return to the depot for maintenance, which was accused of "unfavorable start". Afterwards, when D311/D312 was put into service in 2016 June 30, the service was suspended for about 7 hours due to failure. The train was later sent back to Pat Heung Depot for maintenance.

## Reformation method

The original East Rail Line 8 12-car trains, West Rail Line 28 7-car trains, and Ma On Shan Line 16 4-car trains will be reorganized into 48 8-car trains as follows per consist type:

### Type A

The Type A method is composed of East Rail Line 12-car trains removed and rebuilt with 4 cars. Some of the cab cars have to be decommissioned due to serious roof distortion and replaced by the original Ma On Shan Line cab cars, a total of 8.

Type A1
* Remove M, TH2, PMH and TFH (first-class car card)
* DT1, PM1, TWH, TCH, MW2, PM2 and DT2 reverse 180 degrees horizontally
* TWH converted to TH1
* MWH is converted into MW1, adjusted between PM1 and TH1, no need to reverse
* There is also Type A1', which is the same as Type A1; only the format of the train transmission data is different

   Template:Clr

Type A2
* Same as Type A1; plus:
* DT1 and DT2 are replaced by similar carriages of Ma On Shan Line trains, and are horizontally reversed 180 degrees

   Template:Clr

Type A3
* Same as Type A1; plus:
* DT2 is replaced by the original DT1, no need to reverse
* DT1 is replaced by the same car of Ma On Shan Line train, and reversed 180 degrees horizontally

    Template:Clr

Type A4
* Same as Type A1; only train radio system is different

### Type B

The Type B method is composed of a Ma On Shan Line train adding the remaining 4 truck cards reprogrammed by the Type A method. Among them, the H card can be a newly purchased truck card, or the original {{Eastern train that has been refitted in Japan. There are 8 first-class carriages on the iron line.

Type B1
* Reverse DT1, PM1, MW1, DT2 horizontally by 180 degrees
* Join the new TH1
* The TH2, M and PMH removed from the East Rail Line train were refitted into TCH, MW2 and PM2 respectively, and added to the train. TCH and MW2 do not need to be reversed, and PM2 is horizontally reversed by 180 degrees

Template:Clr

Type B2
* Same as Type B1; except:
* TH1 is refitted from the TFH (original first-class carriage) removed from the East Rail Line train, no need to reverse

Template:Clr

### Type C

In Type C mode, one Ma On Shan Line train is added to another Ma On Shan Line train's P and M cards, new C cards and H cards (newly made or modified from East Rail Line F cards ) consists of 4 columns.

Type C1
* Horizontally reverse DT1, PM1, MW1, DT2 of a Ma On Shan Line train by 180 degrees
* The TFH removed from the East Rail Line train is converted into TH1 and added to the train without reverse
* Add new TCH
* The MW1 and PM1 removed from another Ma On Shan Line train were refitted into MW2 and PM2 respectively, and added to the train without reverse

Template:Clr

Type C2
* Same as Type C1; except: TH1 is also new

Template:Clr

### Type D

The Type D method consists of adding a new H card to a West Rail Line train. Some of the fronts have to be decommissioned due to serious roof distortion and replaced by the original Ma On Shan Line trains. There are 28 trains in total.

Type D1
* Join the new TH1
* MHW converted to MW1

Template:Clr

Type D2
* Same as Type D1; plus:
* DT1 and DT2 are replaced by similar carriages of Ma On Shan Line trains, and are horizontally reversed 180 degrees

Template:Clr

Type D3
* Same as Type D1; plus:
* DT2 is replaced by the same car of Ma On Shan Line train, and reversed 180 degrees horizontally

Template:Clr

Type D4
D533/D534 and D535/D536 expansion method in 2007
* Reverse DT1, PM1, DT2 horizontally by 180 degrees
* Added new MHW, TCH, PM2
* MW1 is converted into MW2, adjusted between TCH and PM2, no need to reverse
* When expanding to 8 cards later, it is the same as Type D1

## Modification of carriages

According to the above reformation method, the required quantities of various carriages are as follows:

```
 96

```
 196

 After recoding

```
 384

```

Therefore, in the reprogramming project, new car cards must be purchased to form a sufficient number of trains, and the types of car cards must be modified:

* Change 8 H cars to C cars for Type B trains;
* Purchase 4 C cars for use on Type C trains.
* Change all F cars (first-class train cars) to H cards for Type B and Type C trains;
* Purchase 32 H cars for 28 Type D trains and 4 Type B and Type C trains.

In the end, there will be 8 D cars (heads/cab car) left, which will be decommissioned and used as spare parts cars. The MTR has transferred the 5 West Rail Line trains with the most serious distortion problem to Pat Heung  and 3 East Rail Line cab cars were retired. The former Ma On Shan Line cab cars took over these positions.

## Platform Instructions Change

### Passenger Information Display

West Rail Line and Ma On Shan Line information display screens will show number of carriages, to remind passengers that the relevant train is a 4-car, 7-car or 8-car train.

With the Ma On Shan Line and West Rail Line as of 2017 December 24 and 2018 May 27 respectively, having all sets 8 cars long, the relevant arrangements are no longer in effect.

### In-Station Announcements

In order to transition with the 8-car trains being put into service, West Rail Line and Ma On Shan Line station announcements have changed the train arrival broadcast content, so that passengers can identify the upcoming trains as 7-car trains/4-car trains or 8-car trains. Hung Hom Station, which did not change the arrival broadcast content when door chime standardization was implemented, had the announcements on the West Rail Line platforms updated.

The Ma On Shan Line and West Rail Line, as of 2017 December 24 and 2018 May 27 respectively, are run solely with 8-car trains, thus the announcements were switched back to the standard ones. However, arrival announcements on the West Rail Line platforms at Hung Hom Station were reverted to KCRC ones.

 Forecast of the next Ma On Shan Line train will be 8 trucks | Cantonese: The next train to (destination) will be 8 trucks, passengers please follow the month Eight trucks with signs lined up on the stage. P: The next train to (destination) has eight carriages. Passengers please wait in line according to the signs of eight carriages on the platform. | The next train to (destination) is an 8-car train. Please wait behind on the designated areas for the 8-car train.

### Label

In terms of West Rail Line, the waiting positions for 7-car trains or 8-car trains, and the location of some facilities in the consist (such as quiet cars) will vary depending on the number of train cars. For the West Rail line: "**turquoise**" and "**Pink**" denote where platform screen doors line up with either the 8 or 7 car consists. As for Ma On Shan Line, the MTR has also added color markings on all station platforms along the line: "**turquoise**" and "**brown**" denotes the area for 8 cars or 4 cars respectively. Some of these stickers also stated where accessible cars were located on each consist.

The Ma On Shan Line and West Rail Line starting from December 24, 2017 and May 27, 2018 respectively, with all trains 8 cars long, the car/door stickers on all platforms were changed to standard MTR ones.

## Project progress

Remark:

* If there is no line color box marked on the "start of daytime off-site test run" and "train re-commissioning", it means that the daytime off-site test run and re-commissioning of the train will start after Tuen Ma Line is fully commissioned
