Network Rail has invited tenders for the design of works planned on the north-east section of the Crossrail route, between Stratford in east London and Shenfield in Essex.
The works include the design of major station improvements at Romford and Ilford and general station improvements along the rest of the 25km route at Goodmayes, Forest Gate, Harold Wood, Gidea Park, Chadwell Heath and Brentwood.
Other works will include various infrastructure improvements including extra train stabling capacity and turnback facilities in order to improve the reliability of passenger services.
