What is rapid train?How it works?

Question

I need some detail about the structure if it's possible!

Answer 1

I have very limited knowledge of high speed rail operations but I'll tell you what I know.

Relative to structure, high speed roadbed usually incorporates concrete cross ties, as opposed to the wooden ones found in most conventional roadbeds.  In addition, there are rubber "snubbers" under the tie plates to help absorb energy where wheel meets rail improving track-train dynamics.

These trains are almost always electrically powered from third rail or overhead "cantenary" electric supply.  This reduces weight as well as improving efficiency.

On some eastern US high speed rail transit systems, the equipment is designed to travel faster on already existing conventional roadbed, and, in some instances, the train tilts as it traverses curvature, the same way one would lean a motorcycle in a curve, allowing for higher speeds.

Answer 2

Group rapid transit (GRT) systems have many of the basic characteristics of PRT, but use larger, shared vehicles. They are intended for less expensive deployment than PRT-systems, and may use on-line or off-line stations.
