43187 leads the 1A78 06:50 Penzance to Paddington GWR service past Brimpton on 14 May 2016. Note the steel pile for the forthcoming electrification just to the right of the power car. Also, in the background are a couple of masts, all on their own, seemingly installed at random. It may seen too obvious, but isn't the most logical way to do a job like this to start at one end, and methodically work your way along, not install a few masts, then have to go back later to add more!
