2-8-2 Steam Locomotives in India

Class AWD/CWD (Locobase 953)

No 21" posted by Vinoo Mathur 29 November 2020 on the "BG War Time Locomotives" page of the Rail Enthusiasts India at [], last accessed 12 November 2025.

Baldwin works numbers (225) were 71761-71925 in 1944, 72113-72172 in 1945. Designated AWD for American WD class.

Montreal works numbers (247) were 71187-71207, 71211-72192, 72948-73567 in 1945.

Canadian Locomotive Company (Kingston) works numbers (340) were 2171-2285 in 1945. 2459 to 2623 in 1948, and 2641-2650 in 1952.

Although described by some sources as based on the IGR XDs, these North American Mikados preceded the primarily British-built XDs (Locobase 20281) by several years. Like other North American designs, the AWD (Baldwin USA) and (CWD-Montreal and CLC inKingston, Quebec and Ontario respectively), IRFCA noted, "cast frames, integrated cylinders, and many other features including robustness in operation" supplanted the older IRS designs in India.

[Locobase note: the list of locomotive builders that follows reflects both a phasing out of steam locomotive production and a shoring up of European builders during the long recovery from World War II's devastation. It also provides a ready comparison of relative outputs for some well-known companies active during the steam era.]

North British Locomotive Company works numbers were 26415-26514 in 1950 (Ten subcontracted to Vulcan Foundry as their works numbers 5996-6005 in 1950) and 27594-27618 in 1955.

Société Anglo-Franco-Belge works numbers 2687-2768 in 1954-1955,of which 64 subcontract to Henschel & Sohn as their 29217-29280)

Henschel & Sohn direct order works numbers were 28984-29043 in 1954.

Krupp works numbers were 3391-3430 in 1954

Wien-Floridsdorf works numbers were 17704-17763 in 1954

Baldwin-Lima-Hamilton works numbers were 76039-76088 in 1955.

Hitachi works numbers 12173-12247 in 1955, 12261-12285 in 1955-1956

Gio Ansaldo & Co works numbers were 1398-1422.

The brand new factory at Chittaranjan in West Bengal began its WG production in 1949-1950 by assembling 100 locomotives. The first few emerged from foreign-produced materials, but local-content percentages rapidly climbed Beginning in August 1956, Chittaranjan turned a total of 1,918 WGs from 1956-1970.

Relatively large Mikado for a non-North American railroad system with one of the largest tenders used outside of the United States. According to Post War Steam, "The engine was designed in such a way that its boiler, motion, springs, axle-box, rear truck and bogies for the tender were all identical to those used for the WP class."

North British Locomotive Company turned out the first 100 of this standard design. Continuing production of more than 2,400 WGs came from India's Chittaranjan Works as well as Austria, Belgium, Germany, Italy, Japan, and the United States. Total production ranks second only to the Chinese Jiefang (JF-1) class described in Locobase 3845.

Dr Sundar commented that the three-course boiler supplied by such British builders as North British and Vulcan Foundry proved to be a bit beyond the capacity of the Chittaranjan Works, which crafted a four-course boiler instead. Even though their bar frames were lighter than the usual plate frames, these locomotives still had a relatively high axle loading and 12" piston(305 mm) valves. Firebox heating surface area included one thermic syphon and two arch tubes.

Friction was reduced by Skefco roller bearings on the eccentric crank, engine leading and trailing trucks, and on the tender trucks as well.

Sundar offers this poignant note about the last locomotive of this class: "The last broad gauge steam locomotive built in India was a WG named "Antim Sitara" (Evening Star). The last steam locomotive built in England was a 9F 2-10-0, also called Evening Star. Evidently, Indian Railways had no originality when it came to naming their engines!"

NB: Tube length is an estimate based on the calculation of tube surface area by subtracting reported firebox heating surface from reported total evaporative heating surface

Class IGR/YG (Locobase 4291)

Data from "Class YG, Type 2-8-2, Service Standard Goods, Gauge Metre" diagram supplied by Vinoo Mathur in his 1 December 2025 installment Post Independence Standard MG Class Locomotives on the railenthusiastindia website at [], last accessed 9 November 2025.

Designed as the standard post-Independence goods locomotive, YGs hauled both freight and passenger trains as circumstances warranted. Designed by Baldwin at the same time it was preparing the YP standard passenger engines (Locobase 2603), Eddystone used the same boiler and firebox components for both.

The YG's cylinder volume was higher than that of the YPs because its cylinder diameter measured an 1" (25.4 mm) more, it still ranked in the lower half of metre-gauge Mikados. Yet its grate and firebox, both large for its gauge, handled the lower-calorie Indian coal, a relatively high boiler pressure and a generous ratio of superheater to evaporative heating surface area wrung more power out of the boiler's output, and its overall design boasted the latest in appliances. The firebox's heating surface included a thermic syphon contributing 33.14 sq ft (3.08 sq m).and two arch tubes.

The last metre-gauge steam locomotive built in India was a YG (3572) delivered in 1972. Tanzania also operated YGs (reconditioned in India before delivery).

According to the Rewari Steam Loco Shed, the Northern Railway operated 168 YGs in the 1970s. Wikipedia reported three YGs still in use on the Western Railway in 1999. All three remain in service at RSLS as museum engines and bear the names Sahib, Sultan, and Sindh.
