Since January, we have been working on the Croxley Rail Link project. The project will divert and extend the Watford branch of the Metropolitan line north-east of Croxley station to the existing terminus at Watford Junction, via two new stations, (Cassiobridge and Watford Hospital) and the existing NR Watford High Street station. We are developing the signalling scheme design to allow other design disciplines to progress and provide information for the implementation contract. The service will provide up to six Metropolitan trains per hour. It is expected that trains will start running in 2017.
