London Underground will take over delivery of the Croxley Rail Link following an agreement reached with the Department for Transport and Hertfordshire County Council over funding.
Building work to re-route and extend the Metropolitan Line to Watford Junction is planned to begin later in the year. It will deliver two new stations at Cassiobridge and Watford Vicarage Road. The existing Watford station will close once the new stations open.
The first trains are expected to run on the extended line by 2019.
It is intended that the plan will support the growth and regeneration in the area, creating new links to Watford General Hospital, Croxley Business Park and Cardiff Road Industrial Estate, which will increase employment opportunites.
LU Director of Major Programme Sponsorship David Hughes said: “Late last year, faced with significant project slippage and cost escalation, the Government asked us to consider stepping in and taking over responsibility for delivery of the scheme. We were clear that a suitable funding package needed to be in place before we would be prepared to take this on.”
