The Western Section route is on existing lines between Bedford and Oxford, Milton Keynes and Aylesbury Vale.
Oxford to Bicester Village has been significantly upgraded by Chiltern Railways and Network Rail as part of the scheme to introduce a new service between Oxford, Bicester and London Marylebone. This project was being delivered as Phase 1 of the overall East West Rail project and includes the additional infrastructure required for East West Rail train services. Chiltern Railways began services from Oxford to London Marylebone via Bicester on 12th December 2016.
Phase 2 of the Western Section covers the route from Bicester Village to Bedford, and Milton Keynes to Aylesbury Vale and Princes Risborough.
The line East of Bicester to Claydon Junction that is currently only used by freight trains will be upgraded for fast passenger services.
The section of rail track between Claydon Junction and Bletchley has been out of use and ‘mothballed’ since the early-1990s and will be rebuilt. A new station will be provided at Winslow.
Train services on the East West Rail line will then follow the existing Marston Vale Line from Bletchley to Bedford. New high-level platforms will be provided at Bletchley, which connects with West Coast Main Line, allowing East West Rail trains to run to Milton Keynes.
The East West Rail project may ultimately include upgrading of the route between Oxford and Bedford to a two-track railway. It is further anticipated that train services will extend to Reading, using existing operational lines.
The Western Section will also provide train services between Milton Keynes and London Marylebone, via Aylesbury. The line between Aylesbury and Claydon Junction will be upgraded to a double track for fast passenger services as part of the East West Rail scheme.
