Testing and Commissioning


The Signalling Testing Division at Trackwork provides a 24-hours-a-day, 7 days a week service for national coverage supporting long-term projects of complete re-signalling systems or short-term assignments such as replacing a signal. The mobile resources teams operate nationally from our three dedicated testing facilities in Doncaster, York and Kettering.

All projects are managed by an experienced Project Manager/TIC, who is responsible for ensuring the approved signal design is installed and commissioned efficiently.

Our experienced, competent Signalling Testers maintain a professional approach at all times and aim to be as flexible as possible to meet clients’ needs around the testing and commissioning of signal equipment.

With access to the right equipment and the most up-to-date information our highly-trained Signalling Engineers can support testing of individual pieces of signalling equipment through to large and complex signalling systems. Clients can be assured that once signal equipment has been tested and commissioned by TICS, the signals will deliver the service and reliability as it was designed to do.
