Piccadilly line extension to Terminal 5/Heathrow Express extension to T5

I had assumed that it was a double tunnel from T123 to T5, with two
platforms at T5.

That's my understanding, though possible with three platforms.

The T4 loop would connect with the eastbound (northern) tunnel just
before the T123 station. To do this, the rebuilt loop will presumably
have to dive under the west-bound (and maybe both) tunnel, whereas the
current version is on the level -- hence the long closure.

Why rebuild the loop? Why not just have the new westbound tunnel dive
under the loop, thus not requiring any rebuilding?

I don't understand the need for the long closure.

I share your puzzlement about how T4 will be served by HEX after T5 opens,
but the details have yet to be announced. My expectation is that it might
indeed be a shuttle between T123 and T4. Passenger flow to T5 will need
more than a half hourly service.

A source which I'd best not name suggested to me a few months ago that
terminal 4 would become a freight only terminal. Is this true? I
don't know. It would, however, explain why plans to get passengers to
terminal 4 seem incomplete.

Hope this helps. Maybe someone else can shed more light.

Well quite. All of the above are multiple platform stations at which some
services from one direction terminate.

AFAIK, The new Heathrow 123 will be the only 'conventional' LUL through
station (e.g. one 'up' platform and one 'down') from which the number of
trains in each direction is unequal.

A quick think gives me:

Archway
Canons Park
Ealing Common
Farringdon (Circle)
Oakwood
Rayners Lane
Rickmansworth
Ruislip
Stonebridge Park
Tooting Broadway
Victoria (Victoria)
West Ham (Jubilee)
West Kensington
Whitechapel (ELL)
Willesden Green


But most, if not all of these are stations with a terminal facilitiy, so are
not the same as the new T123 station at all. The number of trains departing
and arriving each platform from Tooting Broadway, for example, is exactly
the same - the number that leave empty in a southbound direction is equal to
the number that arrive empty on the Northbound platform.

and then posted this ):

There are lots of stations with many more departures in one direction
than the other. For example, Peterborough, Cambridge, Queen's Park,
Harrow & Wealdstone, Watford Junction, Kennington, Baker Street
(Main), Whitechapel, Edgware Road, Aldgate, ....


The only new thing is that there aren't any "all change" trains
arriving.

Roding Valley has 43 eastbound and 51 westbound trains a day with no trains
terminating there.

Maybe you didn't get the message from M L Dickinson, but at Harlesden and
Stonebridge Park there are about 50% more trains to London than there are
from London. This is because the trains which terminate at Stonebridge Park
run empty from Willesden Junction, due to LU not having any staff to perform
the tipping-out duty at Stonebridge Park.

Why can't the driver do it they they do elsewhere on the system?

Because, without assistance from station staff, he has to walk the whole
length of the train and back, checking each car and closing the doors,
and this holds up following trains.

Thats never bothered them on the piccadilly line. Many a time I've been tipped
off at wood green to wait while the driver wanders down the train without any
station staff around. Besides , isn't the driver responsible for the train so
he has to do it anyway?

That's probably because Wood Green isn't a scheduled reversing point,
and hence staff are not routinely available to support tipping out. It
may be worth a slight delay to the eastbound service in order to plug a
very long gap in the westbound.

Re your last point, responsibility doesn't mean he has to do everything
himself. He can accept an assurance from other qualified staff, in this
and other cases.

Also, LU would presumably be fined if they delayed Silverlink trains at
Stonebridge Park, while this is not an issue at Wood Green.
