These were used in Chennai with 1,5 kV DC overhead wires. Goods locos used on the early DC electrified network of SR, and later withdrawn when SR switched to AC traction. They had a provision for coupling to 'ET' class 4-wheeled battery tenders to allow operating on unelectrified sidings, loop lines, etc. These locos 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. There were only seven of these locos; one is now preserved at the NRM (#21900).
Four of these locomotives, designated class EG,{{sfn|Hughes|1992|p=97}} 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to [[Tambaram]] suburban line recently electrified at [[1.5 kV DC]] overhead,{{sfn|Haut|2000|page=49}} and were later withdrawn when the succeeding [[Southern Railway zone|Southern Railway]] switched to AC traction.

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. Its class designation denotes a metre-gauge (Y) DC current (C) goods locomotive (G). With the conversion of the lines to 25 kv AC, all were withdrawn. One is preserved at National Rail Museum in New Delhi.[5]

History[edit | edit source]

Four of these locomotives, designated class EG,[1] 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South Indian Railway's Madras to Tambaram suburban line recently electrified at 1.5 kV DC overhead,[4] and were later withdrawn when the succeeding Southern Railway switched to AC traction. One locomotive, no. 21900 (ex-SIR no. EG1) is now preserved at the NRM.[6]

Design[edit | edit source]

The YCG-1 were able to run on unelectrified lines by operating with ET class 4-wheeled 440 volt battery tenders,[7] of which two were built,[1] containing a capacity of 158 kWh (570 MJ) and a load of 21 LT (21 t).[4] A link mechanism between the two bogies allowed the locomotive to navigate curves easier.[7] The pantographs were of the diamond pattern.[7]
