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 dinning car.
Each part of a train is called a car.
Dining car
The front of a regular train is usually pulled by a locomotive. This is the powerhouse of the train. If your train doesn't have a locomotive, but looks like cars with a window for the train crew, then that can be called the cab car, or as you put it, "the head of a train". There isn't any slang (that I know of) used to call it something special. I uses "front of train", but "head" sounds better. We do shorten "locomotive" to just "loco".

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.

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 puddle is in the front car of the subway train. You have to lead him there, car by car, by getting him to run past you.
