How many gallons of fuel does a train engine hold?
Fuel Tank. This huge tank in the underbelly of the locomotive holds up to 5,500 gallons (20,820 liters) of diesel fuel, plus an additional 300 gallons (1,135 liters) of coolant, and 250 gallons (946 liters) of engine oil.

Today's train locomotives are already quite fuel efficient, especially compared to trucks. In fact, trains can haul one ton of goods an average of more than 480 miles on just a single gallon of fuel, making them 3-4 times more fuel efficient than trucks.
The average figure ranges from 4 to 4.5 litres/ 1000GTKMfor passenger train and for goods train it is2. 25 to 2.75 litres/ 1000GTKM . Being a volatile fluid care must be taken for its storage and handling losses.
Loading of coal and water and incidental maintenance takes a steam locomotive about 1 hour. A diesel engine can be fueled from a pump in 10 minutes or so.
Anyway, the reason for using two locomotives is pretty simple. Twice the number of locomotives means twice the power. This extra power boost is used for especially heavy loads or for trains going up steep grades.
According to the AAR, moving freight by rail is 3 - 4 times more fuel efficient than moving freight on the highway. Efficient use of fuel means fewer greenhouse gas emissions for our planet. (Learn more at the Association of American Railroads' website, http://www.aar.org/.)
Another reason why railroad transport is better than road travel is the fuel efficiency they offer compared to hiring vehicles. Railways can consume up to nine times less fuel for every ton they carry for a kilometer, making trucks fuel inefficient compared to railroad transport.
A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.
Trains create pollution; however, it is important to note that on a passenger level rail is one of the lowest impact public transport methods, in addition the carbon footprint intensity of rail continues to decrease.
If there are only two rails on the line (the ones the trains wheels run on) and there are no overhead lines then, yes, you're correct that the line isn't electrified. There is a very small electric current running through the running rails, used for signalling.
If the train is heading in the direction in which the locomotive end of the train is facing, this is considered 'pulling'. If the train is heading in the opposite direction, this is considered 'pushing' and the motorman or engine driver is located in the alternative cab.
A Brief History. As wireless technologies advanced in the 1960s, freight railroads began adding extra locomotives to the rear of trains to give them enough power to climb steep hills. This is how distributed power was born.

The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.
Even when switchyard locomotives are not moving trains, their diesel engines are usually kept running. This is done to charge batteries, warm engine fluids and meet other operational needs. This can amount to several thousand hours of idling per locomotive each year.
