Let's give the French some credit - at least they consider investment in rail infrastructure on this scale something worth considering. By contrast, HS2▸ here is greeted with little short of hostility, and we cannot even complete electrification of the GWML▸ to get the wires into Bristol's main station (or into Oxford at all).
I reckon that the electrification to Bristol will happen eventually but we may not hear anything until after the Bristol works for the summer. But I wonder if the residents of Bath may have something to say in the matter in the form of pushing for a requirement that the 800s & 802s revert to diesel on the approach to Bath and then switch back to electric for running between Twerton and Bristol
