Full speed ahead: Berlin -Home to the world’s largest test center for railway vehicles.(Deutsche Bahn)

The new suburban railway vehicles for Berlin must complete 160,000 test kilometers ⋅ achieved extensive tests and measurements ⋅ next milestone
The new vehicles of the Berlin S-Bahn have become something like a teenager: mature, fit, ready for anything, but still a little inexperienced. To get the necessary maturity for passenger service, they currently have to pass extensive tests.

Since autumn last year, the first five vehicles turn in Test and Validation Center (PCW) of Siemens Mobility in Wegberg-Wildenrath (Nordrhein-Westfalen) their rounds. Before they can complete their first test runs on the network of the Berlin S-Bahn trains are extensively tested in the world’s largest test center for railway vehicles.

These include:

– so-called development test for interaction between the drive and the brake system
– measurements and type tests for safety against derailment
– tests for electromagnetic compatibility (EMC)
– braking tests to measure the braking distance
– Testing and fine adjustment of the slide and slip protection under different load conditions and different speeds

The type tests of the drive system used to demonstrate the acceleration values and the travel times. Object of the examinations are also function and interaction of the current collector with the current rail Berliner type as well as the error-free detection of busbar gaps and the maintenance of the electric vehicle electrical system within separation points in the Berlin infrastructure.

Peter Buchner, CEO of S-Bahn Berlin:

“We want to introduce from 2021 a vehicle our passengers that brings them reliable, fast and comfortably to their destination. The new trains will therefore intensively tested over a period of two years. We will accompany you as DB AG, the manufacturer consortium closely. “

Sabrina Soussan, CEO of Siemens Mobility, says:

“The Berlin citizens expect S-Bahn, which already work from day one smoothly. With our modern infrastructure, highly qualified experts and innovative testing services in our Test and Validation Center we make a crucial contribution. The PCW makes it possible to carry out tests on 365 days a year, around the clock.”

“The rides on the test ring are another important milestone after each system was put into operation step by step. So we make sure that all of these systems – the drive and braking, to Airconditioning, wipers or door system – are functioning as before the vehicles are allowed to run the then following test runs on the network of the Berlin S-Bahn “says .

So far, the vehicles around 2,000 of the total planned 160,000 test kilometers completed. After completion of the developer tests the detection rides and riding technique type tests can start on special track sections of the Berlin network is expected in late summer of 2019. Also, the test program for the Berlin driving barrier (metal bar to trigger braking force) which is required for the registration, can then be started. In parallel to this demonstration rides of individual vehicles in the Berlin network, the S-Bahn trains will continue to make their rounds in the PCW to provide proof of all specified functions and requirements that are necessary for admission.

The new vehicles will be used on the Berlin ring subnet / Southeast from the 2021st The pre-series includes five half and five quarters trains, which will be delivered in 2020 to go into operation in January 2021 on the line S47 (Spindlersfeld- Südkreuz). The other 96 moves until the end of 2023 to the ring web (S41, S42) and driving on the lines S8 and S46 in passenger service.

About the Siemens Test and Validation Center

In PCW almost all vehicles in standard and meter gauge, and systems and components railway typical undergo tests. With facilities such as high voltage testing, acoustic measurement station, rotary tilting table, tilting device for determining the roll behavior or a vehicle weighing A variety of testing options available. Vehicles and Systems are thereby tested under real conditions or simulated extreme conditions – with static or dynamic tests. The test and validation center has been certified for its testing procedures by independent bodies and accredited so that the results of the examinations for the acceptance of regulatory agencies may be used.
