Network Rail has launched a public consultation into plans for the second phase of the East West Rail project.
Phase 2 of the project focuses on the route from Bicester to Bedford, and Milton Keynes to Aylesbury Vale and Princes Risborough.
Phase one of the project’s Western Section is close to completion. In October, Chiltern Railways and Network Rail will complete a new rail link between Oxford Parkway and London Marylebone.
The project has involved the construction of a new spur line connecting the Bicester Town to Oxford line to the Chiltern main line.
Martin Frobisher, Network Rail route managing director, said: “I am really pleased to have delivered phase one of East-West Rail. A new service from Oxford to Marylebone, from late October, will be a great new option for people travelling to and from the capital.
“As our attention now turns to the future, we want to hear your views in order to properly understand what’s needed for the next phase of this scheme.”
Network Rail said it hopes to submit an application to the Secretary of State next summer.
