Velim railway test circuit

The Velim test center (Czech: Zkušební centrum Velim) is a railway rolling stock testing facility at Cerhenice, close to the city of Poděbrady in the Central Bohemian Region of the Czech Republic. It has become one of the main testing locations for new types of rolling stock designed for use in Europe, and has been a fully accredited European test centre since March 1995. The most notable feature is the Velim railway test circuit (Železniční zkušební okruh u Velimi/Cerhenice), consisting of two large standard gauge railway track ovals designed for continuous running of new rail vehicles.

The centre is owned by the Railway Research Institute (VUZ, Výzkumný ústav železniční), a subsidiary of the national railway operator, České dráhy.

The two standard gauge test circuits were built in 1963, and are located between the villages of Vrbová Lhota, Ratenice, Cerhenice, Velim, Pňov-Předhradí and the southern suburbs of Poděbrady. The village of Sokoleč lies completely inside the larger circuit.

The circuits allows the testing of the characteristics of vehicles, noise levels, the ability to communicate using the European Train Control System (ETCS) and GSM-R radio, and simulation of failures and changes in power system.

Both circuits provide all railway electrification systems used in central Europe:

In addition 1.5-kilometre length can be equipped for third rail supply for metro operators.
