This might be a stupid question - but if the protection is such that
it allows normal services to happen while it's in place, why don't
they just leave it up 24/7?

Because the protection involves shutting off a platform, you would not
be able to handle the peak hour service, Met line every 6 minutes and
Piccadilly every 15 mins to Uxbridge (15 to Ruislip).

At that time of night (2100 isn't it?) the Picc is 20 mins to UXB; but
the point is still the same I guess They most likely just turn one trip
at Ruislip.

In fact I think the Picc is always every 20 mins to UXB other than early
mornings and late nights, the Ruislips increase the service level from
Acton - Rayners. I only have a WTT41 here but it certainly was then and
I've not noticed any serious changes with TT43.

I was referring to the affect on a peak time service of leaving the
protection arrangements in 24/7 which John enquired about.
The Picc in the peaks is booked to run every 15 mins to either
Rayners, Ruislip or Uxbridge, thus a 5 min service up to Rayners
