Test Circuit
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.
- small circuit 3.951-kilometre long with a maximum allowed speed of 90 km/h.
- large circuit 13.276-kilometre long with a maximum allowed speed of 230 km/h for tilting trains and up to 210 km/h for conventional trains.
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:
- 3000 V (DC)
- 1500 V (DC)
- 25 kV AC railway electrification (50 Hz)
- 15 kV AC railway electrification (16.7 Hz)
In addition 1.5-kilometre length can be equipped for third rail supply for metro operators.

Famous quotes containing the words test and/or circuit:
“The test of literature is, I suppose, whether we ourselves live more intensely for the reading of it.”
—Elizabeth Drew (1887–1965)
“each new victim treads unfalteringly
The never altered circuit of his fate,
Bringing twelve peers as witness
Both to his starry rise and starry fall.”
