Network Rail has selected Carillion to deliver the extension works at platforms 5 and 6, to the east of the station, and 12, to the west, as Waverley prepares for Virgin East Coast’s new Azuma trains and ScotRail’s new class-385s.
The enhancements are being delivered as part of the Scottish government’s Edinburgh Glasgow Improvement Programme (EGIP) and the Department for Transport-funded Intercity Express Programme (IEP).
Preparatory works to clear redundant structures and reposition the escalators at platform 11 will begin in April with main construction work on extending platform 12 scheduled to start in May and finish in December 2017.
The extended platforms 5 and 6 should be completed in 2018, while the project will also deliver track remodelling work to allow more trains to use platforms 10 and 11.
Network Rail programme director Rodger Querns said: “Completing such a significant piece of engineering work in the heart of one of the country’s busiest stations will be a significant challenge for our engineers and contractors and we are committed to carrying out these enhancements as quickly as possible and with the minimum of inconvenience for passengers.”
