They are there to allow for the expansion of the rails during hot weather.
Railroad tracks are often called rails.

The different types of barn door rails available for installation include flat track, box track, and round track. Each type has its own unique design and functionality, allowing for various styles and configurations of barn doors.
No. But there was a recent update for detector rails and booster rails. detector rails use redstone to make sensors that trigger things. For example when the cart passes over a track tnt will explode. Booster rails increase the speed.
They use it as a power ground, leaving the running rails to carry (only) the signal (track) circuit currents.
they are well spaced because it is to save money
Its called ballast, and its to allow (rapid) drainage .
