Trains run on tracks, and these tracks guide where the train goes.
When tracks join or divide there are small sections of movable track called 'points'. These can be moved to direct the train onto one track or the other.
The points are not usually controlled by the driver, but by the same signalman who controls the signals which tell the driver when he can go and when he has to stop. The signalman knows where every train is, and where it has to go to, and sets the points appropriately well before the train arrives. The train can then go through the junction without slowing down.
In sidings off the main line there are sometimes manually controlled points, controlled by a lever beside the track. These are simpler and cheaper, but are only used on on tracks which are rarely used, as they require the train to stop and the driver to get out.
They have flanged wheels - so every wheel "steers", but the direction of the train is controlled by the track - thus no "steering wheel" in the cab.

Did who fall on the train track?
A train track is stationary
Train on a Track was created on 2003-08-04.
Classic train tracks (two beams each side) can be removed in favour of a Maglev style track (one bar running through the middle). But essentially no due to the driver having no steering control
no
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.

You need to´change electrical contacts of the train...
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'.
