It depends on the kind of train.

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.

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".
No the train runs one town south to Bayhead only! otherwise north of Point Pleasant Beach.
