Due to a derailment at Willesden Junction, the North London Line will be
running only between North Woolwich and Willesden Junction Low Level via
Gospel Oak until further notice. This uses a line between Kensal Rise and
Willesden Junction Low Level which is normally only served at the extremes
of the day. There will be no service between Willesden Junction and
Clapham
Junction at all.


Thanks, John, for wasting an hour and a half of my time yesterday! ;-)

FYI, virtually all of the NLL services are continuing to use the westbound
High Level platform at Willesden Junction to reverse. Only the first two
trains of the day start from Low Level and one late night train terminates
at Low Level. Otherwise it is, effectively, business as usual from the High
Level platforms (all trains arriving/departing from the westbound platform).
