September 25th – After a bright start, I’d braced myself for a very, very grim commute home, the forecast was awful. As it happened though, it was just drizzly wet, and the wind was behind me. I think I must be getting inured, but I haven’t noticed webs developing between my toes yet. Coming up the ramp at Walsall, I looked, as I often do, at the overhead supply catenary for the railway. The complexity of this system fascinates me, and today, I could hear it crackle and buzz in the wet. Years of design refinement have made this system generally very weatherproof, and that’s a remarkable thing. The 25,000 volts coursing over that metalwork doesn’t take prisoners and will arc long distances in the damp. Railway people are given to calling the overheads ‘knitting’, and you can see why.
