Network Rail has made public details of the second phase of the East West Rail project, which will upgrade the railway between Bicester and Bedford and Milton Keynes and Princes Risborough.
The plans involve upgrading lines or rebuilding defunct lines to link the Great Western, Chiltern, West Coast and Midland main lines north of London.
The first phase of the project to link Oxford to Bedford and Milton Keynes via Aylesbury and Princes Risborough to London Marylebone is almost complete.
The proposed work would involve a new station at Winslow, two new platforms at Bletchley, and construction of 18 new overbridges, 22 new footbridges and subways and changes to 97 railway crossings.

A series of exhibitions on the plans have been set up so that residents can give feedback in person or online.
Network Rail senior programme manager Andy Milne said: “This is a great opportunity for people to come and learn more about the project and tell us what they think of our plans. It gives local communities the opportunity to influence how the project will be developed.”
This is the first round of public exhibitions and more detailed consultation will be carried out next spring. Network Rail hopes to submit an application to the Secretary of State for Transport in summer 2016 for the necessary permissions to complete the work.
