SRAIL 2, the proposed London railway once known as the Chelsea-Hackney line, could end up stopping at neither of its namesake stations.
Transport for London has started consulting on several possibilities for the route linking the south west and the north east of the capital.
The options include a stop at Dalston Junction instead of Hackney Central, and a station at King’s Road rather than Chelsea West. Crossrail 2 is not expected to open until at least 2029 and construction is unlikely to start before Crossrail 1 opens in 2018.
Mayor of London, Boris Johnson, said: “If London and its economy are to keep moving then it’s essential that we crack on and get Crossrail 2 delivered. It’s a vital project not just for the capital, but also for the regions from which hordes of commuters struggle into work on packed carriages each day.”
The public consultation will run until 25 July.
