Electrical power infrastructure for modern rolling stock with regard to the railway in Poland [PDF]
Implementing high-speed trains on Polish railway lines requires a new approach to the issue of power and energy supply via a 3 kV DC power system. Due to the control systems used, modern rolling stock equipped with asynchronous drive allows maintaining a
