A new dive-under at Acton, being constructed by Network Rail as part of the Crossrail programme, is now structurally complete and is on schedule to open early next year.
Currently, passenger services passing through Acton are held up by long freight trains entering and leaving a nearby freight yard. The new dive-under will allow Paddington-bound passenger services to pass under the slower freight trains, avoiding delays, increasing capacity and improving reliability.
Construction of the dive-under began in October 2013. More than 34,000 tonnes of earth were excavated from the 5-metre-wide site that is surrounded by the operational railway, with freight trains passing on one side and passenger trains on the other. More than 1,400 piled foundations have been installed and construction has involved nearly 40,000 tonnes of concrete and the installation of 730 metres of track.
Electric overhead wires to power trains and signals to control them will now be installed before the first test trains use the dive-under at the end of this year. The dive-under will come into full operation at the start of 2017.
When the route to the west of London fully opens in 2019, the Elizabeth line, which will be run by Transport for London, will significantly improve links to the West End, the City and Canary Wharf.
