There were delays on the Piccadilly line tonight but I found the station
announcement at Acton Town most odd. Here is what it said (almost an
exact quote)

"Due to a signal failure at Hangar Lane - Rayners Lane and Uxbridge
trains will be terminating at Northfields".

Can anybody explain how
a) a signal failure on the Central Line can cause delays on the
Piccadilly Line?
b) How trains to Rayners Lane and Uxbridge which do not go through
Northfields can possibly terminate there?

Brimstone has told you all the main info. One additional fact is that
there is a depot at Northfields so the diverted trains can go in there
and then head back to Acton Town to resume an eastbound path at the
appropriate time.
