Standard North American railroad tracks are 54.5 inches apart. This distance is known as the gauge of the rail.
4' 8 1/2"
They bank the rails to somewhat alleviate the centripetal force generated as the train negotiates the curve. Same thing as banking on a road.
for train road
crossing a road is dangerous . rails are rare in track but vehicles are common in road
15 and 50 feet
The speed of sound depends on the medium. There is no particular process that will simply increase the speed of sound.

== == On older sections of bolted track the gaps were put in to allow for thermal expansion of the rails. On continuous welded rail the gaps are not intentional but the most likely result of removing a defect in the rail. Gaps in the rails are most likely not intentional but a result of the steel warping or twisting from the weight and inertia of the constant train traffic. In older sections of track the wood ties that support the tracks my be decomposing causing gaps. Many railroads are upgrading to a continuous rail where they use thermite to weld the rails together at the seems, this improves the stability of the tracks and to improve the rail infrastructure.
The distance between the inner edges of the heads of the rails is called the gauge.
It is literally a bus that is being put on rail. The construction is almost the same with normal road bus, but the wheels are changed so it can travel on rail track,
between 15-50 for a school bus
Both of them, especially if the hazard gates are down.
