We're modernising the Great Western route to bring passengers faster, more frequent, more reliable services. 

On this page you can find out about the work we'll be doing in the Oxford area and when its due to take place.

More about our work to electrify the railway

Oxford Corridor works

Both passenger and freight traffic through Oxford continues to grow so we will deliver a package of schemes to increase capacity, connections and route availability for passengers and freight operators.

  • We are modernising the existing 1960s signalling, which will make train services travelling through Oxford, Didcot and Reading more reliable.
  • We will maintain, upgrade and remodel the track layout around Oxford station. Resignalling, track remodelling and upgrades will allow trains to travel faster, resulting in passengers, commuters and local businesses having access to a brand new half-hourly London Marylebone to Oxford service. 

This investment in the Oxford area will help to grow and support the local economy and will mean that Oxfordshire residents and businesses will be even better connected to places, business, jobs and opportunities.

For further information read our Oxford fact sheet.

Oxford Corridor phase 1 works

From mid-September we will be starting work on phase 1 of our track and resignalling package of works. This phase consists mainly of replacing track, as well as points and signalling work. This will unlock much needed track capacity through the station and is also required to enable electrification in the area. 

We will soon start work on the sidings north of Oxford Station. The up carriage siding will be moved further east and a fifth siding installed, with the access road moving even further to the East.  We will shortly be writing to our neighbours in the area to start a series of engagement meetings to provide further information on this work. A map showing the working areas can be found at download the phase 1 map.

Oxford Corridor phase 0 works

Phase 0 is the package of works required to enable the new Chiltern service to run directly to London Marylebone. The new services are now running with Chiltern Railways running regular services from Oxford, Oxford Parkway to Marylebone.

We have started to erect the new and updated operational building to the east of the station in its new location. This building houses not only facilities for station staff but is used as storage for the retail units and also by Rail Gourmet to prepare food for its on train service.

You can see and download an image of the eastern elevation of the new building.

While work continues, the short stay and disabled car park spaces will remain at the north end of Beckett Street car park, close to the pedestrian bridge over Botley Road. You can see and download an image of the temporary layout of Beckett Street car park.

Phase 0 work has culminated in the closure of Aristotle Lane level crossing. The new footbridge and side span have been installed and are open to the public. Download the phase 0 map.
