Measurement campaign with a tram in Germany

On behalf of Stadler Rail AG, we are supporting the measurement testing of the new tram vehicles for Germany.

 

Approach:

As an accredited testing laboratory in accordance with EN ISO/IEC 17025, we support our customers in demonstrating the safety, reliability, and comfort of new vehicle models — a crucial step on the path to approval and optimization in operation. The focus is on whether the new vehicles meet the requirements for running behavior, ride comfort, and occupational safety. To this end, we record all relevant parameters in accordance with applicable standards and customer-specific specifications – the basis for a transparent and reliable assessment.

More than 40 sensors are installed on the vehicle and the tests are carried out on a route network in Germany. This provides a good representation of real-world conditions.

We use our proprietary ACQUA® software solution for data acquisition. It enables seamless real-time recording of all sensor signals directly on board. Any anomalies can be immediately detected, evaluated, and logged – a decisive advantage for the safety and efficiency of the campaign.

The evaluation is done in accordance with international standards and the specific requirements of our customer:

  • EN 14363 – Assessment of running behaviour

  • EN 12299 – Analysis fo ride comfort for passengers

  • ORE C 116 RP8 (Sperling's ride index / Wz-factor-method) – Comfort and running quality assessment

  • ISO 2631-1 – Evaluation of whole-body virbations on humans

  • ISO 5394-1 - Effects on vibrations on the human hand-arm system

 

Result:

Our structured methodology and precise data collection deliver reliable results on running dynamics, comfort perception, and vibration loads. For the customer, this means:

  • Transparent and comprehensible results for a sound basis for decision-making

  • Early identification of optimization potential in the vehicle concept

  • Strengthening of internal quality assurance through standard-compliant analyses

This enables us to provide our customers with maximum safety, reliability, and planning security — from development and approval to subsequent operation.
