What counts as "very fast" is a matter of definition, but a common one is speeds at least 200 km/h (124 mph). However, high-speed trains usually run at 250 - 300 km/h (155 - 186 mph). The trains themselves are usually streamlined, with an airplane-like or missile-like appearance, thus "bullet trains". However, they use wheels on steel rails, like other trains. This makes them capable of using older rail lines, which they often do, though they go fastest on lines specially built for high-speed duty.

This makes them capable of using older rail lines, which they often do, though they go fastest on lines specially built for high-speed duty. High-speed lines are an important part of HSR systems. They must be very straight to keep the trains on the tracks and to keep the passengers from being shaken back and forth. This means radii of curvature typically greater than 4 km. However, high-speed trains can easily tolerate grades higher than most other trains can, grades higher than 1%. The building of high-speed lines can be expensive, and that expense has been a limiting factor in the growth of HSR. But on the operational side, high-speed trains can easily earn more than enough to cover their costs, unlike relatively slow trains, which often depend on subsidies. In fact, they can do so while being competitive with airlines. In fact, the opening of several HSR lines has led to drops in parallel airline service, often by 50% or more.
