What makes a train a locomotive?

Locomotives. A locomotive is a specialized type of train car which is used to run the whole train. The locomotive is self-propelled, generating energy through the burning of fuel, the use of electricity, magnetic levitation, or other methods. Locomotives can be used to either push or pull train cars.

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.

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.

The majority of modern electrification systems take AC energy from a power grid that is delivered to a locomotive, and within the locomotive, transformed and rectified to a lower DC voltage in preparation for use by traction motors.

MORE DETAILS

Electric trains generally draw power from AC overhead lines. Some DC lines do exist, but they are getting replaced by AC lines. Motors used (traction motors) are generally DC motors. But nowadays they are being phased out in favour of AC motors as AC motors require less maintenance as compared to DC motors.

Sometimes, yes, but more often than not, that second or third locomotive is part of a modern rail technological innovation known as distributed power. Distributed Power Units (DPUs), as they are officially referred to, are locomotives that operate in the middle and/or at the end of trains.

For as long as there have been railroads, locomotive changes have been essential to the officials of the railroads, so that a locomotive could be exchanged for the rest of the trip to the next locomotive changing facility or the destination of the train.
