The next phase proposal will see the railway between Bicester and Bedford and Milton Keynes and Princes Risborough upgraded.
Phase one from Oxford to Marylebone is complete and will commence in October.
The work would involve upgrading and reconstructing underused and mothballed sections of the railway linking the Great Western, Chiltern, West Coast and Midland main lines north of London and providing a strategic east-west route connecting key centres.
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 public views in order to properly understand what’s needed for the next phase of this scheme.”
Phase two plans
- A new station at Winslow
- Two new platforms at Bletchley
- Construction of 18 new overbridges
- Construction of 22 new footbridges/subways
- Changes to 97 railway crossings
Network Rail hopes to submit an application to the Transport Secretary next summer to gain the necessary permissions to complete the work.
