Oh I presumed it would be a 377/2 - DC from Wandsworth as far as Mitre
Bridge then AC after that.

That would have been too simple... *There are a couple of significant
non-electrified bits, eg to get from the NLL to the GW reliefs around Acton
somewhere; and the route from Mitre Bridge Jn loses its OHLE once past the
WCML and turning round towards the SW direction. *(IYSWIM - it is AC as far
as whichever WCML tracks that the SN Milton Keynes service uses, but then
DMU required...)


Oh I forgot about having to cross the fast WCML. Still, how come I
knew about the service from the National Rail Journey Planner, and why
did it appear on the repeater boards at both WR and EB?
