TSI-tests: overhead contact system on Danish railway network

DB Systemtechnik supports Banedanmark

(München, Kopenhagen, 12. April 2016) DB Systemtechnik supports Banedanmark for the TSI-tests of the existing overhead contact system on Danish railway network.

A large part of the Danish state railway network will be electrified in the next years. This electrification programme aims at creating a framework for a more modern railway system responding to the new norms.

The main transit line Padborg – Malmö was already electrified 20 years ago with OCS system types named BDK160 and BDK200. In order to test these “old” systems with regards to the latest TSI-norms, DB Systemtechnik carried out OCS-acceptance tests by order of the Danish Infrastructure Manager Banedanmark.

For this challenging project, Banedanmark commissioned international and experienced partners. DB Systemtechnik brought his expertise for the measurements. Consulting services have been performed by Atkins, while the railway operation has been undertaken by the Swedish company Hector Rail. The test train management has been provided by the Danish railways (DSB).

Test preparation and test train
These TSI-acceptance tests of the overhead contact line (OCS) took place in March 2016 in Denmark on two test sections located on the electrified line Padborg – Malmö:

  • Tinglev - Rødekro for the system BDK160 with a maximum speed of 200 km/h
  • Nyborg - Korsør for the System BDK200 with a maximum speed of 230 km/h.

The test train consists of two well-known Taurus locomotives of DB Systemtechnik and Hector Rail (Siemens type ES64U2, also known as BR182 in Germany) and one measurement coach of DB Systemtechnik.

Nevertheless the Taurus locomotives were not approved in Denmark, which required intense joined efforts between Banedanmark, and DB Systemtechnik and Hector Rail to obtain the approval for the test runs on these test sections.

 

Team, Measurements, Speed record
Under supervision of Banedanmark, the international team carried out the test runs and harmonized its works.

During ten night shifts between 11th and 25th March 2016, DB Systemtechnik used two instrumented pantograph to measure the interaction between the overhead line and the pantograph. Additionally, a stationary optical measurement system measured the uplift of the overhead line.

In addition, the running behaviour of the test train has been monitored by DB Systemtechnik to ensure that the train could run safe above the authorised track speed (speed step-up procedure was used).
Finally, DB Systemtechnik monitored the brake systems and the electromagnetic compatibility (EMC) to avoid any issue with the rolling stock.

Testing the overhead contact line with speeds up to 230 km/h also implied that the danish speed record has been raised: in the night from 21st to 22nd March 2016, the concentration of the team was at its maximum when the top speed of 235,8 km/h was reached on the great belt bridge.

Results
A big amount of data has been collected during these test sessions. The data is now being processed.
