Do we know when construction work is due to start on the Piccadilly
extension to Terminal 5 as I understand that tunneling work was due to
be finished by next year. I also understand that Terminal 4 would be
temporaily closed during the construction period.

Tunnelling is well under way and I believe the station box is all but
finished.

Plans are advanced for the closure of the T4 loop to allow the T5
extension to be connected. I think the latest plan is around December.
I'll try and confirm today at work, but I think we're looking at about a
two year closure.

Will the station be in the JLE style with platform doors or will it be
like T123 & Hatton Cross?

Absolutely no idea, we've not been given that detail.

Has there been a consensus regarding how it will be rendered on the map yet?

If one loop goes HX-T4-T123-HX and the other goes HX-T123-T5-HX, then the
diagram will need to resemble a pair of testicles at the end of the line,
no?

T5 will not be on a loop. Some trains will go HX-T4-T123-HX as now and the
others will go HX-T123-T5(reverse)-T123-HX

So how will that work with the two platforms at T123? Will one be used
exclusively for London-bound trains that have gone round the loop, and the
other for bi-directional trains on a single track extension to T5?

Or will it be one platform be for T5 only, and the other for both sets of
London-bound trains? (which would make more sense to the traveller, but be
logistically more difficult to implement, and result in a bizarre station
where twice as many trains went in one direction as t'other.)

Based on the plans, it would appear to be the above. Wouldn't be that
difficult to implement; the T123-T5 trains would be completely separate from
the T5-T123-CL & T4-T123-CL trains, the only conflict would be the
convergence between the latter two.

I presume that there will be some flexibility retained to allow trains to
reverse at T123, and possibly run trains from T4 into Platform 1 like they
do now.

So how will that work with the two platforms at T123? Will one be used
exclusively for London-bound trains that have gone round the loop, and the
other for bi-directional trains on a single track extension to T5?

That would prevent any T5 bound train entering the T123 platform until a
London bound train had cleared the extension and T123. That doesn't sound
very promising.

It would also be very confusing for passengers wanting to transfer to T5.

Or will it be one platform be for T5 only, and the other for both sets of
London-bound trains? (which would make more sense to the traveller, but be
logistically more difficult to implement, and result in a bizarre station
where twice as many trains went in one direction as t'other.)

That sounds more likely to me. It doesn't sound like it would be
logistically any more difficult. After all for the loop things would be
much the same and for the T5 link it just shifts the changeover from double
track to single track running to the other side of T123. It would also mean
a train could wait in T123 and head for T5 as soon as there the branch is
clear rather than waiting for T123 to be cleared too.

I don't think too many people would find the situation very bizarre.
Whenever I am at a waiting at a station there always seems to be twice as
many trains going the other way :-)

Provided that the junction with the loop doesn't involve a flat
crossover, it will be extremely easy to implement; easier than your
other proposal. Trains from Hatton Cross go into the southern platform
and leave to the west, trains from the west go into the northern
platform and leave to the east. One converging and no conflicting
movements.

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.
