Parallel ones
A Brio train track may be purchased at large retail store websites such as Target and Walmart. One can also purchase this type of train track from Amazon and ebay.
On successful railways it has been found that parallel works the best.
The Vancouver skytrain is a fully automated train that has three lines that run through Vancouver, British Columbia in Canada. It has 42 miles of track along those three lines.
If the track is fed by overhead power lines then the track is the return path for the electric current and is at earth potential.That is 0 volts
They are used so that the railway track doesn't compress or move, and stay's the same so the train doesn't squash the track.
Did who fall on the train track?
A train track is stationary
The type of friction involved in a train moving along a track is mainly rolling friction. This occurs between the wheels of the train and the tracks they roll on. Rolling friction is less than sliding friction, allowing the train to move more efficiently.

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.
