Auxiliary yard

The auxiliary yard is used for the purpose of rolling stock parking in time when tests are not being carried out and performance of stationary tests using power supply from the catenary system, or from the 3 x 400 V / 32 A and 63 A power supply stands. It is also possible to use two high-voltage preheating stands that enable vehicles to be supplied with various combinations of catenary systems by means of a heating cable. The auxiliary yard is covered by a high-speed Wi-Fi data connection.  It includes a track with a R = 150 m curve and two reverse curves (S-curves).

Test preparation halls

The test preparation halls (HPZ) can be used for the purpose of test preparation, installation of measuring equipment, checks of the technical condition of the vehicles under test, electrical and mechanical adjustments, component replacement and other similar activities. All the halls are covered by a high-speed Wi-Fi data connection.

  • There are four separate halls available:
    • HPZ I – length 120 m, 2 tracks, weight per axle 25 t, 111 m inspection pit, footbridges allowing access to the vehicle roof, safety system protecting against fall, compressed air and power supply distribution system, offices, storage areas
    • HPZ II – length 200 m, 2 tracks, weight per axle 25 t, 135 m inspection pit, footbridges allowing access to the vehicle roof, compressed air and power supply distribution system, 5 t crane, lifting jacks, offices, storage areas, meeting room
    • HPZ III – length 60 m, 2 tracks; the hall is used mainly for the purpose of parking of locomotives and VUZ measuring wagons and test preparation
    • HPZ IV – length 22 m, 1 track, power supply distribution system, client facilities and offices

Traction power supply systems

The VUZ Test Centre Velim has its own power supply station including all major European power supply systems. Both the large and small test circuits as well as a part of the auxiliary yard are electrified; they can be supplied separately, thanks to which required combinations of traction systems are enabled.   

ETCS system

The ETCS testing site operated within the VUZ Test Centre Velim is a unique facility in the Czech Republic. The large test circle and the test centre are also covered by GSM-R signal. The VUZ facility uses the installed electronic interlocking technology with real detection means and two radio blocks (RBCs) in combination with track elements (fixed and switchable balises), and thus enables performance of specific customer OBU ETCS integration tests or legally defined ETCS tests, such as ESC tests pursuant to CCS TSI.

Dynamic Test Laboratory

VUZ Test Centre Velim includes a unique facility for static and dynamic component testing, the Dynamic Test Laboratory. More about the Dynamic Test Laboratory
