Flexibly equipped track infrastructure
Different track gauges and power supply systems allow a wide range of test options. A variable DC supply adjustable from 400 V to 2,000 V is available on all test tracks, and 750 V DC on test ovals T1 to T4.
Except for T4, all test ovals are equipped with the following traction current supplies:
Test oval T1
Test oval T1 is more than 6,000 m long and is equipped with train protection systems ATB-EG, ETCS Level 1 and 2 as well as PZB (intermittent ATC). Indusi (inductive ATC) and GSM-R are also provided. Axle loads of up to 26 t can be tested on the large oval at speeds of up to 160 km/h. An English type conductor rail is also laid.
Test oval T2
Test oval T2 is nearly 2,500 m long, with a 300 m curve radius. Axle loads of up to 22.5 t can be tested here at a maximum speed of 100 km/h in standard and meter gauge. The T2 is also used for trams. A Berlin type third rail is also laid.
Test track T3
Test track T3 is straight and flat and as such is particularly suitable for measuring braking distances. Standard-gauge and meter-gauge vehicles with maximum axle loads of 22.5 t attain speeds of up to 80 km/h on the 1,500 m long track. A Berlin type third rail is also laid.
Test track T4
The curve characteristics of the vehicles can be tested on 50, 25 and 15 m radii over a length of nearly 600 m and with axle loads of up to 22.5 t, on both standard and meter gauge.
Test track T5
The shortest test track, at approximately 400 m, is the gradient track. T5 has an up-gradient of 40 ‰ and a down-gradient of 70 ‰. Vehicles with axle loads of up to 22.5 t can be tested here on normal and meter gauge.
Options with ETCS
The infrastructure equipment of this large test ring makes it possible to simulate a journey from Germany to Rotterdam, including dynamic ETCS transitions and changing between different power supply systems.
