High-speed rail service (Polish: Kolej dużych prędkości) commenced in Poland on 14 December 2014, with the introduction of 20 non-tilting New Pendolino trainsets operating on 4 designated lines radiating out from Warsaw. Polish State Railways started passenger service using Pendolino trains operating at a maximum speed of 200 km/h on 80 km line Olszamowice-Zawiercie (part of railway line called CMK, from Warsaw to Katowice/Kraków). From December 2017 there are two 200 km/h sections, 136 km long in total.[1][2] All high-speed services operated by PKP in Poland are branded as Express Intercity Premium (EIP).
