  • Watford area renewals programme

    Working with train companies and specialist contractors, we've upgraded the infrastructure and signalling around Watford Junction to improve performance on the West Coast main line

  • Easter 2015 - thank you for your patience

    Over Easter, we demolished a rail-over-road bridge south of Watford Junction station and replaced it with a new bridge. The team also replaced track, signalling and junctions, and we made some essential repairs to two of the Watford tunnels to the north of the station.

    The work has helped to increase reliablility and will allow trains to travel more quickly along that part of the route.

    Why have we done this work?

    Over the past 15 years, the number of trains using the West Coast main line has doubled - and it's getting busier. Much of the infrastructure around Watford dates from the 1960s and has become unreliable - it is a particularly heavily used section with trains running round the clock.

  • What work have we delivered?

    We have replaced three critical junctions the north and south of Watford and renewed the signalling system in the area. Work to complete the renewal of Watford North Junction, which was postponed as a result of the Harbury landslip on the Chiltern route in February, will take place at a later date, yet to be determined.
    We’ve replaced the track crossovers with track that is easier to maintain, reducing future disruption.

    Fewer delays, better journeys

    We have:

    • Renewed all signalling between Kings Langley and Bushey to give more flexibility and a quicker return to normal service after disruption.
    • Installed 11 new gantries and 39 new signal posts.
    • Laid over 9 miles of new track, giving you a smoother journey.
    • Replaced 21,000 tonnes of ballast and 11,000 sleepers.
    • Modified the overhead power lines to increase reliability.
    • Reconstructed Orphanage Road bridge at Watford to allow line speeds of 125 mph.
