TfL website:
The Piccadilly Line has no service between Acton Town Station and
Hyde
Park Corner Station in both directions.

Where do trains which terminate at Hyde Park Corner switch from Southbound
to Northbound tracks for their return journey? What is the highest level
of
frequency that can be provided north of Hyde Park Corner in circumstances
where all trains are turning back at Hyde Park Corner?

What was happening today was that all trains were tipping out at Green Park.
They were then running empty to Hyde Park Corner where the driver changed
ends in the westbound platform and then reversed back east over the
crossover, effectively using HPC WB platform as a reversing siding. Given
that we only ever ran 17 or so trains on the CKHPC bit of the line, this
didn't cause any problems with blocking back. Had we needed to, we could
have increased our reversing capacity by using Down Street, but as far as I
know the need didn't arise.
As for highest frequency of reversers at HPC, a good rule of thumb is to
take the time allowed for the T/Op to change ends (four minutes) plus one
for luck and call it one train every five minutes, or 12tph. BTW for all you
trainspotters, track bashers and other railway enthusiasts, from a trainside
operating POV the Piccadilly line *never* runs north south, it only ever
runs east west (no matter which point of the compass the leading cab is
actually facing).

Where does an westbound Heathrow train become eastbound? T4 ot T123?

It's been said in here several times that T123 is the timetabling point.
However when I was on one such train recently I noticed that the
displays inside the carriage changed to "Cockfosters" at T4.

Presumably for the benefit of people boarding at T123? Drivers have long
been changing the destination blind at the penultimate station, both to
advise those joining the train at the terminal and to save a minute or two
allowing for a pee or a can of tea.

In fact, it's normal to change the destination at (or just after departing
from) Hatton Cross, so that people waiting at T4 and wishing to get into
town don't get confused by a train turning up with "Heathrow" on the front
(at least, that's the way I used to do it). The operational switch from WB
to EB takes place at Heathrow 123.

Cheers Steve - Hatton X WB would seem logical, but how many people board at
T4 for T123, especially when the HX is free between these two points?

Passengers also board at T4's only platform for stations east of T123
therefore it makes sense for them to know where the train is going..

Depends on where the driver bothers to reset them.

Hatton Cross Heathrow 123 via T4 is 'Heathrow Loop'. The rest is
east/west bound.

I trust, Steve, that as one of our top T/Ops you'll be resetting at or just
after HX?

I always do it at a point when I don't need to be in full control of my
train :-)
