A major milestone in the construction of the new Elizabeth line station at Liverpool Street has been reached with the completion of the two new platforms over 30 metres below ground.

The two 240 metre long platforms, constructed as part of the Crossrail programme, were pre-fabricated in more than 500 pieces at a state-of-the-art factory over 130 miles away near Sheffield. They were then transported to London, lowered down the station’s main shaft and pieced together below ground.

The new platforms have taken around four months to install and are around twice the length of many existing London Underground platforms to accommodate the new 200 metre long Elizabeth line trains.

Rohan Perin, Crossrail Project Manager at Liverpool Street station said: “Assembling the two platforms piece by piece over the last few months has been a bit like putting together a giant jigsaw puzzle. Prefabricating and then assembling the sections together on site has meant that we can get on with the job quickly and safely.”

The Crossrail project is approaching 75% complete and is being delivered on time and on budget. The project is now focussed on the complex job of fitting out the stations and tunnels with the equipment and systems needed to operate the railway.

Nearly four kilometres of platforms have been constructed at stations in central London. The platforms are now complete at all stations from Paddington to Woolwich, apart from Whitechapel where construction is ongoing.

The Elizabeth line station at Liverpool Street will open in December 2018 when two fully accessible ticket halls will provide an interchange with Liverpool Street to Shenfield services, the Northern, Central, Metropolitan, Circle and Hammersmith & City lines, as well as National Rail services. An estimated 124,000 passengers will use the station every day.

Once fully open in 2019, the Elizabeth line will significantly improve links to Liverpool Street and the City, cutting journey times to Canary Wharf, the West End and Heathrow.
