Crossrail, due to launch in December 2018, will not open until autumn 2019, it has been announced.
The central section, between Paddington and Abbey Wood has had its opening date pushed back — with Crossrail's press team claiming that further time is required "to ensure a safe and reliable railway for customers".
The revised schedule is needed to "complete the final infrastructure and extensive testing required to ensure the Elizabeth line opens as a safe and reliable railway."
Simon Wright, Crossrail Chief Executive said:
The Elizabeth line is one of the most complex and challenging infrastructure projects ever undertaken in the UK and is now in its final stages. We have made huge progress with the delivery of this incredible project but we need further time to complete the testing of the new railway. We are working around the clock with our supply chain and Transport for London to complete and commission the Elizabeth line.
