Commuters hoping to use London's troubled Crossrail service will have to wait until 2020 at the earliest, the project's new boss revealed today.
Chief Executive Officer Mark Wild told ITV News he could 'say for certain' there was no chance of the £17.6bn railway opening in 2019.
Asked if the Elizabeth Line would be ready before 2021 Mr Wild said he did not know but 'would very much hope so.'
The planned royal opening in December 2018 was cancelled in August and a revised launch date of Autumn 2019 has also been abandoned.
The east-west railway linking Shenfield and Abbey Wood with Heathrow Airport and Reading includes 10 new underground stations and more than 40km of tunnels beneath central London.
Construction work on the stations is months behind schedule and 'dynamic testing' of the new trains only began last month.
Mr Wild estimated 60,000 tasks need completing before the railway is declared safe.
