Cardiff Area Signalling Renewal (CASR)

Atkins delivered the Signalling and Power and Distribution contracts for the CASR which have modernised life-expired signalling equipment across 192 route miles of track between Newport and Port Talbot. 

A technically challenging project, CASR was one of the first major signalling schemes in the UK to use latest innovations such as plug couplers and Frauscher train detection technology to help save time and money. 

Over the course of the scheme, the team undertook a range of tasks, including centralising control of signalling equipment to the Cardiff Control Centre, installing an electronic crossing controller system and providing an improved power and distribution system. 

Completed in 2016, this project has provided more efficient and reliable passenger and freight services to meet demand in the South Wales region.
