200 km/h on the Westbahn: Vehicle tests applying a digital measuring system

The private railway WESTBahn is operating in 2-hours-cycles from Vienna via Linz to Salzburg. The fleet consists of double deck trains of the type KISS by Stadler Rail. Henceforth, parts of the fleet will be operated by DB. For the extended approval of Germany, PJM was in charge of the type tests in the field of brakes and acoustics. "The test runs were successfully performed in a very short time frame", says Martin Joch. The three main factors for this were:

Due to a limited timetable, the "Corona weeks" in March were ideal to perform the test runs.
To a great extent, the measurement chain was digitalised. The advantages of a digital measurement system are the reduced cabling efforts and a much higher interference resistance. Within a short period, our team had implemented a measuring system comprising 200 sensors.
The many years' experience and great committment of our measurement team.

The static tets, dynamic brake tests and tests of the wheel slide protection system were performed under varying conditions, such as differing conditions of the track and varying speed ranging from 80 to the maximum of 200 km/h.

S-Bahn Berlin: PJM finished approval tests of new suburbal trainset

The suburban fleet of S-Bahn in Berlin will be modernised from 2021 on. 382 new vehicles will provide more comfort, light and safety. 2015, the consortium Siemens Mobility GmbH and Stadler Pankow GmbH started to develop a new trainset "DB 483 and 484". For these new trainsets, PJM was in charge of the approval tests in the fields of fatigue strength, structural requirements of railway vehicle bodies and torsional vibrations of the wheelsets. A complex projekt like this reqires a many years' experience of worldwide projects of an accredited testing facility.

These figures show the complexity of this project:

Periods of test runs: 10 weeks
Generated data from the test runs: 2 terabytes
30 telemetry channels and 400 measurement channels
