List of high-speed trains

The following is a list of high-speed trains that have been, are, or will be in commercial service.

A high-speed train is generally defined as one which operates at or over 125 mph in regular passenger service, with a high level of service, and often comprising multi-powered elements.

In these tables, two or three maximum speeds are given: the column "Operated" refers to the maximum speed reached by the train in commercial operations, while the column "Design" refers to the theoretical maximum speed in commercial operations as announced by the manufacturer. Finally, a third "Record" speed may also be listed if there is an independently verified speed record.

Conventionally wheeled locomotive-hauled
As trains can have multiple configurations on the same service, service name is used as an identifier.
