Centenary celebrations of South Eastern Railway

"Stamp issued on the occasion of the centenary celebrations of South Eastern Railway on 28th March 1987 features an HP class locomotive built by Vulcan Foundry Ltd." This 5 ft. 6 in. gauge locomotive first worked on EIR. HP class locomotives were later reclassified as HPS class, when a superheated version was developed. This is the only example of a BESA design appearing on an Indian stamp.
