The locomotives of India presently consist of electric and diesel locomotives. Steam locomotives are no longer used in India, except in heritage trains. A locomotive is also called loco or engine.

The Bengal Sappers of the Indian Army were the first to run a steam locomotive in India. The steam locomotive named Thomason ran with two wagons for carrying earth from Roorkee to Piran Kaliyar in 1851, two years before the first passenger train ran from Bombay to Thane in 1853.


Classification of locomotives[edit]

In India, locomotives are classified according to their track gauge, motive power, the work they are suited for and their power or model number. The class name includes this information about the locomotive. It comprises 4 or 5 letters. The first letter denotes the track gauge. The second letter denotes their motive power (Diesel or Electric) and the third letter denotes the kind of traffic for which they are suited (goods, passenger, mixed or shunting). The fourth letter used to denote locomotives' chronological model number. However, from 2002 a new classification scheme has been adopted. Under this system, for newer diesel locomotives, the fourth letter will denote their horsepower range. Electric locomotives don't come under this scheme and even all diesel locos are not covered. For them this letter denotes their model number as usual.

A locomotive may sometimes have a fifth letter in its name which generally denotes a technical variant or subclass or subtype. This fifth letter indicates some smaller variation in the basic model or series, perhaps different motors, or a different manufacturer. With the new scheme for classifying diesel locomotives (as mentioned above) the fifth item is a letter that further refines the horsepower indication in 100 hp increments: 'A' for 100 hp, 'B' for 200 hp, 'C' for 300 hp, etc. So in this scheme, a WDP-3A refers to a 3100 hp loco, while a WDM-3F would be a 3600 hp loco.

Note: This classification system does not apply to steam locomotives in India as they have become non-functional now. They retained their original class names such as M class or WP class.

Heritage Gallery of Indian Railways[edit]

The classification syntaxes[edit]

The first letter (gauge)

The second letter (motive power)

  • D – diesel
  • C – DC electric (can run under DC overhead line only)
  • A – AC electric (can run under AC overhead line only)
  • CA – both DC and AC (can run under both AC and DC overhead line); 'CA' is considered a single letter
  • B – Battery electric locomotive (rare)

The third letter (job type)

  • G – goods
  • P – passenger
  • M – mixed; both goods and passenger
  • S – shunting (also known as switching engines or switchers in the USA and some other countries)
  • U – multiple units (EMU/DMU)
  • R – Railcars

For example, in "WDM 3A":

  • "W" means broad gauge
  • "D" means diesel motive power
  • "M" means suitable for both goods and passenger service
  • "3A" means the locomotive's power is 3,100 hp ('3' stands for 3000 hp, 'A' denotes 100 hp more)

Or, in "WAP 5":

  • "W" means broad gauge
  • "A" mean AC electric traction motive power
  • "P" means suitable for Passenger service
  • "5" denotes that this locomotive is chronologically the fifth electric locomotive model used by the railways for passenger service.

Company designs[edit]

In the nineteenth century, the various railway concessions ordered locomotives to their own specification, usually from British manufacturers. This multiplicity of similar, but different designs, increased manufacturers' costs and slowed production. During the 1890s, British manufacturers had full order books, so Indian railway companies looked to Germany and the United States for locomotives.[1]

British Engineering Standards Association (BESA) designs[edit]

After acrimonious words in The Times and Parliament, the British Engineering Standards Committee (later British Engineering Standards Association or BESA) began to design a series of locomotives for use by all railways in India. The first two designs emerged in 1903: a 4-4-0 passenger, and 0-6-0 goods. The designs were revised in 1905 and 1906 with additional types added due to requests for heavier and more powerful locomotives:

  • Class SP – Standard Passenger – 4-4-0;
  • Class SG – Standard Goods – 0-6-0;
  • Class PT – Passenger Tank – 2-6-4T;
  • Class HP – Heavy Passenger – 4-6-0;
  • Class AP – Atlantic Passenger – 4-4-2;
  • Class HG – Heavy Goods – 2-8-0;
  • Class HT – Heavy Tank – 2-8-2T.

These BESA designs however were advisory, not mandatory, and were customized by the railway companies to their own taste. The railway companies could not even agree to use the same classification system: only the state operated railways used the class designations SP, SG, PT, HP, AP, HG and HT. Once superheating became accepted, superheated versions were classified SPS, SGS, etc. if built with superheaters, and SPC, SGC, etc. if converted from saturated to superheated.

Indian Railways Standards (IRS) designs[edit]

After World War I, new, larger, more powerful locomotives were designed by the British consulting engineers to the Indian Government. These started to appear from 1927 onwards:

Left:Indian Railways locomotive XP class 1935, Right:Indian Railways class locomotive XB class 1927
  • Class XA – branch passenger 4-6-2 design, 12.5-ton axleload;
  • Class XB – light passenger 4-6-2 design, 17-ton axleload;
  • Class XC – heavy passenger 4-6-2 design, 19.5-ton axleload;
  • Class XD – light goods 2-8-2 design, 17-ton axleload;
  • Class XE – heavy goods 2-8-2 design, 22.5-ton axleload;
  • Class XF – light shunting 0-8-0 design, 18-ton axleload;
  • Class XG – heavy shunting 0-8-0 design, 23-ton axleload;
  • Class XH – 4-cylinder 2-8-2, 28-ton axleload (none built);
  • Class XP – experimental passenger 4-6-2, 18.5-ton axleload;
  • Class XS – experimental 4-cylinder 4-6-2, 21.5-ton axleload;
  • Class XT – light tank 0-4-2T, 15-ton axleload.

World War II designs[edit]

During World War II, large numbers of 2-8-2 locomotives were acquired from the United States and Canada, and were designated as classes AWD and CWD respectively. The Baldwin Locomotive Works adapted the USATC S160 Class locomotive design India which became class AWC. 60 broad gauge locomotives were built in 1944 as part of an order of 180 locomotives to the S160 design. In addition to modified frame spreaders, axles, cylinders, and cab, the Indian locomotives had a turbo-generator and electric lighting fitted, which was not included in the standard design for use in Europe. Many parts, including boilers, were identical to those used for the standard gauge locomotives.[2]

Indian Government Railways (IGR) standard designs[edit]

Shortly before World War II, new classes were designed; but it would post-war before many of them came into service. These new designs were signalled by the change of broad gauge prefix from 'X' to 'W'. In addition, plans were put into place to start manufacturing locomotives in India. The new classes were:

Left:Indian Railways locomotive WL class, Right:Indian Railways class locomotive YG class
Left:Model of a (decommissioned) WP Steam Locomotive at Guntur Division, Right:Model of a (decommissioned) Indian Railways steam locomotive M2-162

All broad gauge steam locomotives in India have been withdrawn from normal service, with only occasional steam specials continuing to operate.

Converted locomotives[edit]

WCDS6 is a converted YDM4 locomotive into a broad gauge locomotive. This rebuilding was carried out by the Golden Rock shed. It was built for large industrial concerns. The first one was delivered to RITES. Rest being same, new water and air lines are added. They also have a modified control stand and dual brake system. Also, they have Broad Gauge bogies and under-frames.

Diesel multiple units[edit]

Left:Indian Railways DHMU, Right:Indian Railways DEMU

A few routes in India currently have Diesel multiple unit service. Depending on the transmission system they are classified as DEMU (diesel-electric transmission) or DHMU (diesel-hydraulic transmission). There are diesel railcar service in a few places known as 'railbus'.

DC electric traction[edit]

Note: These locomotives are no longer used, or were used only in sections around and in Mumbai which was the only location in India using DC traction.The power operated is 1500V DC. Now even last section of Central Railway between Thane to Mumbai CST (Main Line), Nerul to Thane (Trans-Harbour Line), Vadala Road to Mahim (Harbour Line – Connecting C.R. with W.R.) and Panvel to Mumbai CST (Harbour Line)has been converted to AC traction (25kV).
