A train track is stationary
Train on a Track was created on 2003-08-04.
Yes, train wheels remain in contact with the track at all times. The tracks support the weight of the train. They also guide the train. The wheels are shaped such that the train remains balanced on them. Any slight movement of the wheels sideways is automatically corrected so that the wheels remains exactly on the middle of the rails. If the wheels were not in contact with the track, the train would be flying.
A train doesn't know which track to go on, it has no intelligence! What happens is that the signalling systems switches the train left or right at forks in the track known as points. These have small pieces of movable rails which direct the train onto the desired track.

The motion of a train on a moving track depends on the reference frame you choose. In the train's frame of reference, it may appear stationary or moving at a constant speed. However, in an external, stationary frame of reference, the train would appear to be moving at a different velocity that combines the train's speed with the speed of the track.

It is normally called a 'single track'.The alternative is when two or more tracks run in parallel, this is called a 'double track' or a 'multiple track'.
