Older trains if they were steam depended on how hot the fire was and modern day trains have electronic devices
(electro) Magnets in the "track".
speed trains and trains to transport people
No, the other trains in Britain and Scotland cannot travel faster than the trains in the high speed one.
High speed trains are rail transport that utilizes technology to travel significantly faster than traditional transport. High speed trains first started to run commercially in 1964 at Japan, and were known as the bullet trains.
Yes
as fast as they want
If two trains are passing each other the relative speed can be found by adding the individual speeds of the two trains. This applies if the trains are passing each other in opposite directions. Should one be passing the other and both be moving in the same direction, the difference of the individual speeds would be the relative speed of the trains.
High speed rail trains generally run on standard tracks that are continuously welded together. The trains are made to have better aerodynamics so that speed can be increased.
It controls , example the regulator controls the fans speed.
The high speed trains of Japan will nudge 200 mph.
50 mph
Their speed, efficiency, and punctuality.
