I’d like to see the whole of the GWR mainline network electrified within my lifetime, however that’s going to be impossible to do all at once so I would suggest completing it in stages as follows:
2021
- Bristol Parkway/Patchway - Bristol Temple Meads
- Didcot - Oxford - Banbury
2022
- Chippenham - Bath Spa - BTM
- Reading - Basingstoke
2023
2024
- BTM - Taunton including Weston Super Mare loop
- Newbury - Bedwyn
2025
- Bristol Parkway - Bromsgrove including Gloucester spur
2026
2027
2028
- Bath Spa - Westbury
- Chippenham - Melksham - Trowbridge
2029
2030
- Exeter - Plymouth/Paignton
- Bromsgrove/Cheltenham - Worcester - Hereford
2031
2032
2033
2034
2035
- Plymouth - Penzance/Newquay
2036
- Exeter - Exmouth
- Exeter - Barnstaple
2037
- Westbury - Salisbury - Southampton
2038
- Carmarthen - Pembroke Dock/Milford Haven/Fishguard Harbour
2039
This will leave the Greenford, Windsor, Henley on Thames, Marlow, Gunnislake, Looe, Falmouth and St Ives branches unelectrified, but they can be operated using battery powered units.
