Great Western Main Line £400M signalling upgrade underway

The £400M scheme to modernise the 1960s signalling infrastructure on the Great Western Main Line has started, Network Rail announced yesterday.

The four-year scheme, once completed, could help cut delays by 50%, according to Network Rail. The work will also ensure that the signalling infrastructure is compatible with an electrified railway.

“In a few years’ time, the signalling infrastructure will be considered life-expired but we are ahead of the game by starting the improvements now,” said Network Rail route managing director Patrick Hallgate.

Signalling contractor Invensys has been appointed as main contractor for the work.
