Yes if electric locos are available, sure they should be used. But I want to know is whether that "Gooty Diesel" is able to get the job done??? If yes, then I dont think its a wastage of fuel. As I have studied powerplant economics in my graduation, I came to know diesel engine is no waste and create less pollution than electric locos when you see the cost of coal involved and pollution created by thermal power plants.

agree... but the cost of diesel is main concern area.. n if the powerplant economics is considered, it there are hydel and nuclear plants available... n production of electricity is extensive thng as every one needs that... we can balance that by using electric loco (in railways case), cng vehicles etc etc...

It can be compared when you see the economics behind operating a diesel locomotive and that of electric locomotive. Yes at the time of idling, rich fuel-air mixture goes into the engine so at that time, electric is more efficient. Regarding eog, its efficiency depends on load of working. For bct rajdhani, eog is efficient but for trains like bpl-indb double decker and hwh-dhanbad dd, the same eog will consume same fuel for comparatively less load hence less efficient.
And thanks for info on operation of eog in bct rajdhani. :)

Railways operates round a year while hydel plants cannot operate throughout the year at same load. In summer, hydel plants will not be able to satisfy the needs of IR. For nuclear plants, its proportion is quite small compared to thermal plants. India is facing extreme scarcity of enriched uranium so these plants operate on per day basis. And cng vehicles are there in delhi and few more cities but all over India, petrol and diesel are chiefly consumed. Example if you observe the freight transportation, traders are preferring road transport rather than railways.
