is it engine?
The engine most of the times.
If it's a powered locomotive, then a locomotive. If it's a car with a cab to control the train, then a cab-car. If it's a train powered by itself, called a Multiple Unit (MU) with the engine part of the train, the front is called, well, the head end.
The car at the head of the train is typically the locomotive or engine, which is responsible for pulling the train and providing power. It is usually located at the front to ensure proper control and visibility for the train driver.
In most cases the car at the front of a train is the engine or the locomotive. However, sometimes the train is pushed from behind and then the engine is the car at the end.
A train is faster than a car, because it has more powerful engine.
An engine heads a trains, with cars behind it, and the caboose the last car. NOTE: If a train is heavy with freight, it may have several engine 'cars' pulling it, AND even pushing it from the back. NOTE: There are several types of train "cars".
