High-speed railway:

High-speed railway, referred to as high-speed railway for short, refers to a railway system with high design standards and high speed for the safe running of trains. Its concept is not limited to tracks, let alone trains. High-speed rail has different regulations in different countries, different times and different scientific research and academic fields.
