In what is seen as a beginning to adopting green fuel, the Indian Railways launched its first CNG train based on dual fuel system of diesel and CNG. The Rewari passenger train, just flagged off, consists of two power cars and six car coaches and will have a capacity of carrying 770 passengers. Of the total fuel consumption, it will consume over 20% of CNG over a distance of 81 kms in two hours.
Indian Railways had first announced the induction of a CNG train in its fleet at the last Rail Budget. Manufactured by Integral Coach Factory at Chennai with CNG conversion kit supplied by Cummins, Indian Railways is planning to run more such CNG trains in the future. This increased use of CNG trains will considerably reduce dependence on diesel consumption.
Switching over to CNG trains will see considerably lower emission of toxic and carcinogenic pollutants and zero particle matter thus not only reducing the carbon footprint of the railways but also providing capacity to use cheaper and alternate fuel. Use of CNG on trains will aid in cutting down carbon monoxide by 90%, carbon dioxide by 25%, nitrogen oxide by 35% and non methane hydrocarbon emissions by as much as 50% while operating costs will be reduced by 50%. The Indian Railways are also considering solar and wind powered propulsion trains in the future.
