Not only does China have trains, but it can lay claim to some pioneering engineering feats, including being the first (and only) country in the world with high-speed trains running along conventional tracks achieving 350kph/217mph.
Defining "high-speed rail" as the regular operation on new purpose-built track of trains running at speeds of 250 km/h or more, the first high-speed (and, so far, only) line in England is the Channel Tunnel Rail Link (opened in full in November 2007) on which trains operate at up to 300 km/h.

speed trains and trains to transport people
Eurostar is the brand name for the high speed trains running London-Paris and London-Lille-Brussels.
The first trains were much slower than modern trains. For instance, in Britain, Robert Stephenson's Rocket, 1829, had a maximum speed of 28 mph (45 km/h).
The first locomotive was built by Richard Trevithick and had a top speed of about 4 mph (miles per hour).
No, the other trains in Britain and Scotland cannot travel faster than the trains in the high speed one.
Older trains if they were steam depended on how hot the fire was and modern day trains have electronic devices
Yes
Both maglev (magnetic levitation) trains and high-speed trains utilize electromagnets, but in different ways. Maglev trains are lifted and propelled by powerful electromagnets, allowing them to float above the tracks and achieve speeds exceeding traditional trains. High-speed trains, on the other hand, typically rely on conventional tracks and use electromagnets for braking and traction, enhancing their speed and efficiency while maintaining contact with the rails.
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.
