Several of them wiped their pantographs off on the tunnel entrance in
the early months of the GN electrification.

I think we established on a uk.t.l thread recently this couldn't have
happened.

I'm sure you're right about it being a myth - but a good story
nonetheless.

AIUI it has happened on Thameslink at Farringdon (as up trains have to be
able to leave pan up if they're going to Moorgate, but must be pan down to
go through the Smithfield Tunnel to City Thameslink and Blackfriars).

Presumably no "train using DC" detection as used at the top of Camden
Bank ?
