Expert report for approval of new trams in Dortmund
Customer: HeiterBlick GmbH, Germany
Project tasks
- Assessment of running dynamics
Our Approach
For the approval of the new trams of the operator DSW21 in Dortmund, the manufacturer HeiterBlick GmbH in Leipzig commissioned the EBA-approved expert Stefan Bühler to assess the running dynamic behaviour according to the regulations for trams in Germany, BOStrab.
The new vehicles have been authorised and in operation since April 2024. Modernised vehicles will be assessed in a further phase.
PROSE agreed on the scope of verification with the technical supervisory authority of North Rhine-Westphalia (TAB NRW) and the manufacturer HeiterBlick GmbH. Dr Johannes Keudel, a specialist in running dynamics simulations, supported Stefan Bühler in the assessment of the provided evidence. Finally, the expert report was drawn up.
Customer benefit
It is essential for the customer that the authorities accept the assessors. Thanks to the appraisal team’s high level of expertise, the customer HeiterBlick GmbH knew precisely what evidence he had to provide and in what form. For this reason and thanks to the high level of customer orientation of the PROSE team, the expert report could be prepared quickly and in good quality. Although the input on this specialist area was only available very late, this hardly caused any delay to the authorization of the trams.
