Testing: Utrecht Light Rail line “Uithoflijn”

Testing: Utrecht Light Rail line “Uithoflijn”
26 September 2018



The local government tendered the main contract for the new light rail project for the city of Utrecht to BAM. The requirements included coordination and verification of system integration tests (SIT) with external parties.

Ricardo was asked to advise BAM in meeting its contractual duties regarding system integration tests, with a focus on vehicle track interfaces.


  1. We mapped the project interfaces which led to an overview for BAM of responsibilities and a clearer understanding of the activities related to contractual agreements.
  2. This was followed by the creation of the overall test plan, with the scope of work for testing in different phases (an iterative process between the relevant stakeholders)
  3. The test protocols were then developed, based on system requirements and an analysis of potential risks. Customised work plans were set up, tailored per interface and based on requirements for specific project phases or geographic locations.
  4. Ricardo’s teams then supported the project with operational, tactical and strategic test expertise along with specialist domain advice, such as on vehicle and track.

Results and benefits

  • Coordination and performance of more than 100 tests, resulting in the verification of safety and contractual requirements.
  • Despite being a dynamic project - driven by external influences – our client, BAM, was able to use our support and experience to respond pro-actively to changes in requirements and circumstances, regarding scope, time and money.
  • A mutually-agreed Interface Design Report between three parties for Vehicle Track interface
  • Clear, traceable baseline for integration test scope
  • Efficient test plans and test runs with detailed results
