When a Diesel Locomotive Starts, it consumes almost 3-4 times more fuel than its average fuel consumption. That is why Railways prefer to keep the engine running even if the halt at a station is for 30 minutes. If we turn off the engine and turn it on again in 30 minutes, the diesel consumed would be around 350 liters for a normal huge locomotive, in this much amout of fuel, Locomotive could have gone for around 100 KMs that is a running of like 2 hours. So basically for a stop of more than 2 hours only the engine is turned off. This data varies for different locomotives.

A huge locomotive uses an average of 1.5 gallons of diesel per mile (352 L per 100 km) when towing about five passenger cars. Locomotives towing hundreds of fully loaded freight cars use many times more fuel that this, so even a five or 10 percent decrease in efficiency would quickly add up to a significant increase in fuel costs.

In reality no one train is directly run by diesel engine like busses and car. Here the fuel burnt and output of the rotational torque is used to run the generator. Then this electricity is regulated and the motor will run. In a locomotive each shaft having single motor. A single loco having 6 shaft with the pair of 12 wheels. The speed is controlled by regulation of current by rheostat method…
