New Delhi: New Delhi: Stung by the rising fuel costs, Indian Railways has developed medium powered multi-genset locomotive for future use. A prototype locomotive comprising of 3 gensets of 800 Horse Power (HP) each amounting to a gross HP of 2400 is under going trials at Itarsi of Bhopal Division in West Central Railway.
In a multi-genset locomotive, two or more small engines are used compared to a single large engine in conventional locomotives. The smaller engines work only when there is an increased power demand resulting in reduction in fuel consumption by about 20 per cent for delivering the same power by an single large engine. It reduces NOx emissions as well as have a smaller carbon footprint.
There are 500 multi-genset locomotives with medium HP in use in USA and railway engine manufacturer Bombardier has a order of 200 multi-genset locomotives from the German state Railways. Us manufacturer US manufacturer National Railway Equipment Company (NREC) has introduced these engines in Australia too.
Canada is also experimenting with similar engine and has reported 20 to 70% fuel saving and 70 to 90% reduction in noise. In terms of emissions, the average reductions amounted to 20 to 25 tons of NOx and 225 to 250 tons of GHG per year.
