Class IGR/WG (Locobase 2479)

Data from [], last accessed 15 July 2007.

Relatively large Mikado for a non-North American railroad system with one of the largest tenders used outside of the United States. This was a standard design the first 100 of which were delivered from North British Locomotive Company. Many others were built at the Chittaranjan Works as well as in Austria, Belgium, Germany, Italy, Japan, and the United States

See [] and [] (accessed 15 July 2007). See also "The South Bank Exhibition No 1 - Transportation", Engineer, Volume 191 (4 May 1951), p. 563.

Dr Sundar commented that the three-course boiler supplied by such British builders as North British and Vulcan Foundry was 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. Friction was reduced by Timken 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)

See [] . in which we find that these were first imported from Germany and the US (among other countries), but later built in India by Telco and Chittaranjan Loco Works. 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).
