Crossrail's diveunder and flyover

摘要

Network Rail has issued design tenders for a flyover and diveunder for Crossrail.rnSituated at the west end of Acton freight yard, the diveunder will enable freight trains due to head west along the Great Western Main Line to leave the yard without affecting passenger trains, thus increasing freight capacity.rnThe flyover will be located at Stockley, in the busy Heathrow Airport Junction area of West London, and will be used by trains to and from the airport as well as those on the GW Main Line.
