Indian locomotive class YCG-1. The YCG-1 was a class of electric locomotives built in the 1930s for use on the metre-gauge electrified lines in the Chennai area. The name stands for (Y)metre gauge, (C)DC electric, (G)goods. With the conversion of the lines to 25 kv AC, all were withdrawn. One is preserved at National Rail Museum in New Delhi.

History 
Four Bo-Bo locomotives were supplied by English Electric in 1930 for goods traffic on the South Indian Railway's Madras to Tambaram suburban line recently electrified at 1.5 kV DC overhead, and were later withdrawn when the succeeding Southern Railway switched to AC traction. One is now preserved at the NRM (#21900).

The YCG-1 had a provision for coupling to  4-wheeled battery tenders supplying 440 volts, to allow usage on unelectrified sidings, loop lines, etc. These tenders, of which two were built, had a capacity of , and weighed . 

The locomotives had a roughly rectangular, box-like body with a cab at either end, with a short platform extending from each cab. The cabs each had a door opening on to the platform, and a window (on the right) at the ends. The two bogies had interconnecting linkages to allow easier negotiation of sharp curves. Two 'diamond' style pantographs for current collection.

Indian locomotive class WDS-5. The class WDS-5 is a diesel–electric locomotive used by Indian Railways for shunting and doing departmental works. The model name stands for broad gauge (W), Diesel (D), Shunting  (S) engine. The WDS-6 is used all over India.

History
The class was imported in 1967 to address the need for powerful shunting locomotive that will be able to haul 20-24 coach rakes. The previous WDS-4 class was underpowered for this kind of operation. They were manufactured by BLW varanasi using the kits provided by ALCO. The WDS-5 can easily be recognized by their shot nose and flat-ended cab at one end. Some were sold and transferred to industrial concerns and public sectors, but have IR road numbers on them.

Indian locomotive class WDS-2. The Indian locomotive class WDS-2 was a class of diesel-electric locomotive that was developed in 1954 by Krauss Maffei for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Shunting locomotive (S) engine, 2nd generation (2). They entered service in 1955. A total of 20 WDS-2 was built in Germany between 1954 and 1955, which made them the most numerous class of shunting diesel locomotive until the WDS-4B.

The WDS-2 served both shunting and departmental trains for over 45 years. As of January 2020, all locomotives have been withdrawn and subsequently scrapped. None of the 30 locomotives have been preserved

History 
These locomotives were imported from Germany in 1954. They are based on the Krauss-Maffei ML 400 C with the power-pack of Krauss-Maffei ML 440 C. They were among the first diesel locomotives of India. They were very noisy in operation.

Indian locomotive class WDS-3. The class WDS-3 was a diesel-hydraulic locomotive used by Indian Railways for shunting and doing departmental work. The model name stands for broad gauge (W), diesel (D), shunting (S) 3rd generation (3). The WDS-3 is used mostly in the Northern Railway Zone (NR). All these locomotives were withdrawn and scrapped by the late 1990s.

History 
The history of WDS-3 class starts in the early 1960s with the aim of the Indian Railways to address the growing requirement for a new shunting locomotive class. These locomotives were designed by Maschinenbau Kiel (MaK) to the specifications set by the Research Design and Standards Organisation (RDSO). Many aspects of this locomotive were taken from the DB Class V 60.
They use Suri hydrodynamic transmission developed for these diesel locomotives and were designed as shunting-cum-shuttle service locomotives. For this purpose, the reversing gear box attached to the Suri transmission was designed to have two gear stages; in the lower gear, designated as "shunting gear", the locomotive was designated to have a maximum speed of 27 km/h and in the higher speed gear designated as "mainline gear", the maximum locomotive speed was 65 km/h. The locomotive was fit for both shunting and mainline type of services up to a limited speed of 65 km/h. Subsequently, it was decided to manufacture locomotives of similar type ingeniously by Chittaranjan Locomotive Works (CLW). These locomotives are designated as WDS-4  class. 

When the lot of 7 WDS3 shunters came, initially they had a lot of troubles with these locomotives, but the trouble was confined more to the power pack than to the transmission. But in course of time, going into detail about the troubles that were being experienced and the mechanics were able to get over a lot of these difficulties and in-fact the transmission was also modified to suit with the engine. Between 1976 and 1978 all seven units were rebuilt to WDS-4B specifications by CLW, and received a new engine and a simplified transmission. These units were reclassified as WDS-4Cs. By 1990s all units were withdrawn from service and were scrapped.

Indian locomotive class WDS-1. The class WDS-1 was a diesel-electric locomotive used by Indian Railways for shunting and carrying out departmental works. The model name stands for broad gauge (W), Diesel (D), Shunting (S) 1st generation (1). The WDS-1 is used mostly in the Northern Railway Zone (NR). All these locomotive s were withdrawn from service by the late 1990s.

History 
During World War II, the USATC took effective control of the ports of Bombay, Calcutta and Karachi and obtained 50 General Electric built Bo-Bo diesel locomotives to operate them. These were a standard General Electric 45 ton design of locomotive. When delivered to India the locomotives were split between the BAR, the Bombay, Baroda and Central India Railway (BB&CIR), the Great Indian Peninsula Railway (GIPR) and the North Western State Railway (NWR) and were used for working military traffic between the ports and mainline railways. After the war they became the property of the mainline railways and in turn became IR locos. Post war they were designated as ADE class and on IR they were WDS-1 class. One unidentified member of the class has been preserved and is now at the Diesel Locomotive Works (DLW), Varanasi.

Upon the departure of the Americans, the locomotives all became part of the stocks of their respective companies. In August 1947, 14 of the locomotives fell under ownership of the Pakistan Railway. All NWR examples were among these, along with two each from BBCIR (6500-01), GIPR (6526-27) and the BAR pair. They became their ADE36 class with the running numbers 6501 to 6514. The ones that remained in India became ADE class locos and were numbered 410 to 425. All but one of these 15 became WDS-1 class locos and received the numbers 19000 to 14. The missing loco was sold to CLW for use as their works shunter where it remains albeit now preserved.

Indian locomotive class WDS-8. The Indian locomotive class WDS-8 was a class of diesel–electric locomotive that was developed in 1979 by the Chittaranjan Locomotive Works for Indian Railways, but ended up being delivered exclusively to the private sector. The model name stands for broad gauge (W), Diesel (D), Shunter (S) engine, 8th generation (8). They entered service in 1979. A total of five WDS-8 locomotives was built at Chittaranjan Locomotive Works (CLW), Chittaranjan between 1979 and 1982.

All WDS-8 units were sold to the Steel Authority of India. As of November 2020, these locomotives have been withdrawn from service.

History 
The history of the WDS-8 class began in the early 1970s with the Railway Board's dual aims of addressing the shortcomings of the preceding WDS-4, and to remove all of Indian Railways' steam locomotives from operational service by a target date of 1990. The WDS-8 was a competing bid from CLW to the Banaras Locomotive Works's WDS-6 class, intended for industrial concerns in the private sector as well as for the Railways itself. The WDS-8 had a MAK diesel engine with a maximum output of 800 hp, which was similar to the engine used in the newly upgraded YDM-1 class. They possessed short cabs modeled on those of CLW's electric locomotives with a single long, narrow hood. 

 which were then transferred to the plants of the Steel Authority of India (SAIL).

As of November 2020, no locomotives of this class are in service.

Indian locomotive class WAG-1. The Indian locomotive class WAG-1 was a class of 25 kV AC electric locomotives that was imported from Europe in the 1960s for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G) locomotive, 1st generation (1). A total of 112 WAG-1 were built by The European Group 50 Hz Group/European Group/50 Cycles Group (consortium) between 1963 and 1966. They entered service in 1964.

The WAG-1 served both passenger and freight trains for nearly forty years. As of January 2002, all locomotives have been withdrawn from service, with one being preserved at the National Rail Museum.

History 
Forty-two locomotives of this type were ordered from European Group. Five of these were completely assembled in Europe and the remaining were built at CLW. A repeat order was placed on for 20 locomotives in 1963. Further these locomotives were manufactured at CLW. The typical feature of these locomotive is the Monomotor bogies. This construction results in substantial saving in weight in traction equipment and gives better adhesion. The traction motors are force ventilated and are fully suspended type. These motors are permanently grouped in parallel and are controlled by tap changer and field weakening. This can be used for a multiple unit operation to a maximum of four locomotives. Compressed air brake for the loco and vacuum brake for the train are provided, in addition, these locomotives have been provided with regenerative braking. Few locomotives have been converted to dual brake system. They were in service until 2002 when all but one were scrapped. The first indigenously CLW produced WAG-1 20710 'Bidhan' is preserved at the National Rail Museum, New Delhi.

Indian locomotive class WAG-2. The Indian locomotive class WAG-2 was a class of 25 kV AC electric locomotives that was imported from Japan in the 1960s for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods traffic (G) locomotive, 2nd generation (2). A total of 45 WAG-2 locomotives were built by The Japanese Group (a consortium of Mitsubishi, Hitachi and Toshiba) between 1964 and 1965. They entered service in 1964.

The WAG-2 served both passenger and freight trains for nearly 40 years. As of January 2001, all locomotives have been withdrawn from service and scrapped.

History
These locomotives were built by a consortium of Mitsubishi, Hitachi and Toshiba (The Japanese Group, as attested by a plaque fixed on their sides) as an alternative to the European-built WAG-1. They were delivered in 1964 and had a greater horsepower rating than the WAM-1 but had similar Bo-Bo wheel arrangement (4 wheels per bogie) with four Hitachi DC traction motors connected to the wheels permanently in parallel through a WN geared drive. The WAG-2 had Ignitron rectifiers just like the WAG-1, but some were later refitted with Excitron rectifiers. Some even had the Mitsubishi logo painted on their sides.

None of the WAG-2s had been retrofitted with air train brakes. Like the WAG-1, they were also used around the ER-SER-NER-NR circuit as it was the first AC electrified area, and hauled ordinary passenger trains and freights only. They were also used double-headed on freight trains. They had four traction motors permanently coupled in parallel are fed by ignitron rectifiers. Speed control was by a tap changer on the input transformer. Mitsubishi transformer, 20 taps. Oerlikon exhauster and compressor, Arno rotary converter. They were based at Asansol Loco Shed of Eastern Railways and then transferred to Bhusawal and Itarsi sheds of Central Railways in 1985. Due to aging, the WAG-2 locomotives were withdrawn in 2001. None have been preserved.

Indian locomotive class WAG-6A. The Indian locomotive class WAG-6A is a class of 25 kV AC electric locomotives that was developed in the 1988 by Allmänna Svenska Elektriska Aktiebolaget (ASEA)  for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Goods (G) engine, 6th generation (6) First variant (A). They entered service in 1988. A total of 6 WAG-6A were built at ASEA, Sweden between 1987 and 1988. they were the most powerful locomotives in India until the arrival of the WAG-9 class.

All locomotives of this class have been withdrawn from service, with 1 unit earmarked for preservation.

History 

The history of WAG-6A begins in early 1980s with the aim of addressing the shortcomings of the previous WAG-1, WAG-2, WAG-3, WAG-4 and WAG-5 classes and remove steam locomotives from IR by a target date of 1990. The WAG-5 were a great successes but these locomotives were based on 1960s technology and fast became underpowered for the expanding Indian railways. So Indian Railways decided to look for a new locomotive. At that time (1980s) Thyristor controller was vastly used by locomotive in many European rail networks while 3 Phase AC technology was still in its infancy. So the ministry of railways floated a tender for a 6000HP locomotive with Thyristor control. The following responses were received:

 ASEA submitted their model with 6000 hp with Bo-Bo-Bo bogies and Thyristor chopper control.
 Hitachi submitted their model with 6000 hp with Bo-Bo-Bo bogies and Thyristor chopper control
 Hitachi also submitted their model with 6000 hp with Co-Co- bogies and Thyristor chopper control

Each company submitted their prototypes and Indian Railways designated these prototypes as the WAG-6A class WAG-6B class and WAG-6C class respectively. IR ordered 6 of each class and these were delivered in 1988.

Specification 
Manufacturer: ASEA ( WAG 6A )
Build dates: 1988–89
Wheel arrangement: Bo-Bo-Bo
Traction Motors: ASEA make (WAG-6A), L3 M 450–2. Six motors, fully suspended, force-ventilated, separately excited, 3100 kg.
