Anyone know what caused the westbound Piccadilly line to be so bad
this morning? It took me nearly an hour and a half from Turnpike Lane
to Northfields starting just before 10am.

I know part of the delay was caused by a passenger alarm that caused
the train to stop about half a car short of the normal stopping point,
and that took more than 5 minutes to be resolved, but even after that
it was very slow... and the driver kept making announcements about
disruption to the eastbound service, which confused me!
