Urban rail signalling - growing the UK’s world-class urban rail 

The UK’s urban rail systems are regarded as the safest and most efficient in the world, and Thales plays a vital role in developing and safeguarding this reputation. 

We provide world-leading technology and expertise for the UK’s major underground and light rail systems. The Communications-Based Train Control (CBTC) technology that we developed is now a ‘default standard’ for urban train control and we cover more kilometres of track with our CBTC system than any other supplier.

Thales’s SelTrac®, LockTrac® and FieldTrac® systems lead the world in signalling technology, while our range of traffic management and communications systems ensure safety, efficiency and comfort for millions of passengers.
