Indian Railways have taken initiative of using Compressed Natural Gas (CNG) as an alternate fuel on pilot project involving Diesel Power Car (DPC) of Diesel Electric Multiple Unit (DEMU). Contracts for conversion of 50 DPCs have been placed on three different firms by Indian Railways Organisation for Alternate Fuels (IROAF) for Northern Railway Shakurbasti Diesel Shed homing DEMUs.
Fitment of these kits is under progress. Such technology has not been tried out on any other major railroad on such a scale. It involves extensive trials and testing.
Cost of fitment on 50 DPCs is about Rs. 55 crore and savings in fuel consumption can be assessed only where these kits are positioned.
