Put safety at the heart of your railway operations

What is rolling stock testing?

Railway vehicle manufacturers, suppliers and rolling stock operating companies are required to meet mandatory, voluntary and contractual requirements for the construction, commissioning and operation of rolling stock and components. Rail testing companies provide independent, third-party assessment of rolling stock and components to ensure they are compliant with relevant standards. Testing will put the product through a series of different tests to receive authorisation for commissioning.


Testing of railways and components as well as rolling stock certification provides multiple benefits:

  • Comply with contractual requirements, as well as any national and international rolling stock regulations to put your product into service
  • Discover potential safety and approval-relevant weaknesses early in the development phase, to address them and avoid costly rework and delays
  • Ensure safety for passengers and drivers by demonstrating your quality with a globally recognised certification mark
