Useful map thank you. Depending on your definition of proposed, Henley was also planned alongside Basingstoke and Windsor branches. And Oxford to Leamington, Coventry and Nuneaton as part of electric spine, although that was more tenuous.
At Oxford the colouring seems to meander just onto the Cotswold line but I'm not sure that the GW electrification would have gone beyond the carriage sidings immediately north of the station.
Pretty sure I have read fairly recently of an intention to wire from Wolvercot Jn towards Evesham, maybe to the first station, which in my atlas is Hanborough. Is there a new park and ride operation planned using 387s maybe ? Indeed, did I dream it ?
Yes, I read something about it. But my impression was that the scheme's pretty aspirational at the moment - plans haven't been submitted for approval, and no funding has been earmarked. So i'd say it's a bit premature to include, until things progress further
Agree Roger. Oxford is a massive massive problem with so many through trains (pass and freight) as well as the suburban services. The whole station needs rebuilding, resignalling and wiring but there isn't really much of an alternative available. If land wasn't an issue then building a temporary double track "avoider" to the west and maybe a temporary south bay whilst the station is demolished and rebuilt.
It strikes me that a number of the shunts in and out the carriage sidings to the north would be unnecessary if there were a couple of south end bay platforms for the terminators and starters.
In the period when electrification to Oxford was still meant to be part of the main GW scheme, Network Rail produced a couple of maps showing the planned extent of wires at Oxford for public consultation events.
The first showed the 25kv finishing just north of Wolvercot junction (known since the recent resignalling as Wolvercote North junction) on the Banbury line.
The later version showed them stopping short of Wolvercote. Some sort of equipment for the power supply is meant to be located close to Oxford North junction (the Bicester line junction) so the wires would have to carry on at least as far as that whatever happened.
The proposals for electrification on to the Cotswold Line are just that at the moment, as part of aspirations to extend Thames Valley stopping services out there (and removing lots of shunt moves at Oxford station) to encourage more park-and-ride traffic from Hanborough and nearby communities into Oxford and beyond by offering a high-frequency service. No detailed design work for electrification has been done - unlike at Oxford - and there is no commitment to go ahead, nor funding in place at the moment.
At Oxford station, the track layout installed during the resignalling scheme was designed with a station rebuild in mind, allowing for two island platform either side of the existing quadruple track through the station and a north-facing bay on the city centre side which has the potential to become a fifth through platform.
I have attached a slide showing the first electrification plan for the Oxford area - but can't find the other one at the moment - and a small pdf indicating the intended future layout for the station.
The current intention seems to be to create a new platform 5 on the west side of the station first, then move on to the city centre side, including a new main station building and concourse

Oxford Corridor Phase 2
The rail infrastructure in the Oxford Station area is reaching full capacity and cannot accommodate any forecast in service enhancements as anticipated in the 2024 indicative train service specification.
Therefore, to increase capacity, Oxford Corridor Phase 2 is being developed, and subject to funding, will provide the following improvements:
- A new platform will be achieved by building another platform face (Platform 5) and associated track to the west of Platform 4, creating an island platform. The platform will include new customer facilities including a café, toilets, waiting room and train staff facilities, with a new canopy the full length of the island platform.
- A new entrance on the western side of the station with retail outlets and customer facilities in the new concourse area. Step-free access to Platforms 4 and 5 will be provided via a subway from the new western entrance to a new lift and stairs up to platform level. Platform 4/5 will also remain accessible to the rest of the station and the main (east) entrance concourse via the existing footbridge and lifts.
- A new track bridge span over Botley Road to accommodate the track to the new Platform 5.

A NEW plan to overhaul Oxford's railway station will be drawn up.
Plans to redevelop the city's railway station, on the edge of Frideswide Square, have been in the pipeline for more than a decade, with the most recent efforts for a blueprint of how this might look coming to a head in 2017.
Now, a new 'Master Plan' will be written to replace the previous one, with the announcement that engineering consultancy firm Atkins has been brought on board to oversee the project.
