Railways workers on the night shift

Sir, — As I was on my way home from London at about 11.30pm on Thursday last week, I spotted rail workers walking along the line through Twyford station (bringing back memories of the famous Johnny Cash song I Walk The Line). I assume they were working on the electrification project, which is topical so I thought the photo might be of interest. — Yours faithfully,
