Testing and validation

State-of-the-art infrastructure and qualified testing under one roof

Locomotives, entire trains, trams, metro vehicles – just about every type of rail vehicle makes its way to Wegberg-Wildenrath at some time or another. That’s because it’s home to the world’s largest certification facility for rolling stock: Siemens Mobility’s Test and Validation Center Wegberg-Wildenrath (PCW) – with certification and accreditation from the state and a success story stretching back over 20 years.

Testing, validation, and certification of your vehicles and systems

The PCW offers speed, braking, curve, and gradient tests. For every kind of technology, every vehicle, every system, every market.

The accredited and certified Test and Validation Center in Wegberg-Wildenrath is your ideal partner for the testing, validation, and certification of your rolling stock and systems. Here we can perform typical railway tests on practically all standard-gauge and meter-gauge vehicles as well as systems and components – 24 hours a day, 365 days a year, independently of public rail network operations. Twenty-five percent of the vehicles tested come from other companies. The Center also makes its infrastructure available to third parties.


Facilities like measurement track curves, turn-tilt tables, and the vehicle weighing system provide a host of testing options that give you as rail operator the results you need for acceptance tests by certification authorities. Vehicles and systems are tested under real-life conditions or simulated extreme conditions, with static or dynamic tests. This service is provided at the Test and Validation Center or right at your own location.

Comprehensive test equipment for every vehicle

Simulating reality on 30 km of test track


So you’ll always stay on track

A 50 meter-long measurement track with a curve radius of 150 meters and two measurement fields is available for determining wheel support and guidance forces. The safety of vehicles against derailment is assessed here in accordance with DIN EN 14363:2005.


For controlling every turn

Traveling through curves, over hills, and across dips can be simulated at a standstill. Both standard and meter gauge vehicles are tested on the turn-tilt table. The following tests can also be carried out: testing the freedom of movement between bogie and vehicle body, and determining the rotation torque of bogies.


So your ride is always stable

Corresponding tipping equipment is available for measuring vehicle rolling characteristics. Here the effect of transverse accelerations such as centrifugal forces or side winds can be simulated on the test bed by means of tipping.


For whisper-quiet travel

Compliance with legal noise limits is essential: The authorities are extremely precise and withhold approval if a rail vehicle is only one decibel louder than allowed.

Your vehicles can be subjected to a noise test at speeds of up to 99,4 mph on an acoustic measuring rig in accordance with TSI Noise and DIN EN ISO 3095:2005. This is much easier than testing them on the public network during normal operation. The condition of the track complies with strict European approval regulations and is regularly inspected.


To keep the weight within limits

Eight weighing elements are provided on a 52 meter-long, leveled, standard-gauge track. The distance between these elements can be varied. The load-bearing capacity per wheelset is 30 tons, with a measuring range per wheel of between 1 and 180 kilonewtons. The measured values have a resolution of 50 newtons. This makes it possible to determine the precise weight of your vehicles.


To guarantee safety in an electric railway environment

Lightning and switching impulse voltages can be applied for test purposes using the IP5/200L impulse voltage test system. This system has functions for switching impulse (250/2500 µs) and lightning impulse (1.2/50 µs), with parameters in accordance with DIN EN 60060-1. Alternating and direct voltages can be tested on the AC/DC high-voltage test system according to DIN EN 60060-2 with 10 kV AC, 100 kV AC and 135 kV DC.
