Serious arcing at Farringdon
Was waiting at Farringdon the other day and an A stock train came into
the eastbound platform , stopped and almost immediately one of the outside shoes started to arc badly, probably the worst I've ever seen as it literally went on for 2 minutes while the train was sitting waiting for a green signal and it was very bright too, almost like an electric arc welding torch. Is there no way the driver can be warned about this by some sort of in cab equipment as I can't imagine it did the shoegear or the live rail much good. Seems to happen a lot at farringdon tho. Couldn't perhaps the gaps in the power rails be shifted slightly so when the trains stop you don't get shoes almost but not quite touching them? B2003 |

B2003 Happens, or at least used to, with A stock at Liverpool Street, too. The rear shoes can be partly on the ramp where the conductor rail starts after a crossover. Occasionally I've seen a spectacular arc for the entire station stop. |
