I agree, and this would be a good time to announce replacement of at least the worst bits. Time to act quickly, partly to outmaneuver the NIMBYs.
It seems a fairly frequent occurrence for the OHLE to fail, more so around Paddington.
Not aware of it being so much of an issue for other London termini.
From recent comments above, Paddington has older OHLE compared to other stations.
Whilst it would seem prudent to replace asap, that cost would have to be authorised by the DfT» , and probably they are happy for Network Rail/GWR▸ to take the blame and not authorise additional expenditure.
Yes, out as far as just beyond Hayes the electrification was done 'on the cheap' in the late 90s for the Heathrow Electrification and was virtually all headspan.
Several of the 'least worst bits' have been replaced over the years, usually around junctions where there is most risk. You can see this here with the area concerned at between 9-10 minutes in:
https://www.youtube.com/watch?v=TMADOeBumAU I agree that all other areas should be replaced as soon as possible. It is little use having very reliable OHLE, as we do, from 11 miles out of Paddington, if the first 11 miles are still susceptible to widespread damage in the event of failure.
Lines have now been re-energised between Reading and Stockley Bridge (between West Drayton and Hayes) so
AIUI▸ an electric service can now operate as far as Slough/West Drayton from the Reading direction.
