Answer 1

There's no standard definition, but a railway system designed for speeds above 250kmph is generally called high speed -sections of these routes may have lower speed limits for safety reasons. Only 16 nations have high-speed railways -China boasts the world's longest network with 27,000km of such tracks. Japan, Spain, France and Germany are the others where tracks dedicated for high-speed trains stretch over 1,000 km.
