I thought the plans for T6 put it in place of T123 , with a T5A & B
being built first.

I'm not sure of BAA's intended timescales, but 'Heathrow Central' would be a
new terminal on the site of and replacing T123, while T6 will be adjacent to
the railway between Hayes & Harlington and T123. Accordingly, with three
stops HEx and Crossrail trains will be able to serve T6, Heathrow Central
and T5, or T6, Heathrow Central, and T4. Do LUL have any plans to get the
Piccadilly Line to T6, and if so, how?


I'd think any such plans would basically be advanced by BAA as opposed
to LUL these days - that's broadly how the tube extension to T5 came
about. Of course LUL would be integrally involved in any such plans -
e.g. working out how the new service would run - but the model of how
things were done with T5, where BAA paid for the extension and then
got it built, would surely be followed. Apart from anything else it's
hard to see any Mayor of London exercising themselves or indeed the
TfL budget over serving a new airport terminal they don't want (and I
can't really see any future Mayor adopting a fundamentally different
policy on this).

You are making a LOT of sense. *Thanks for posting.

Thank you.

I did a bit more thinking about this, and while I think the trains
_should_ go on to Euston, I'm now of the opinion that David Rowlands
might be serious in terminating them short at Old Oak. The reason is
simple: gauge clearances. It's going to cost a pretty penny to get the
Camden tunnels cleared for LGV gauge.

There is a solution though, and it's staring us in the face. You need
to build the short connecting tunnel between Old Oak and Kensal Green
anyway so that you can link HS1 to HS2 effectively, but don't, for the
time being, run double-deck trains through it. Instead, divert a bunch
of 'regular' trains that would have terminated at Paddington into it
(say, whichever lines have finally landed up electrified by then), and
use the space freed up at Paddington for your new supertrains. There
are far fewer gauge issues between Old Oak and Paddington than there
are between Kensal Green and Euston.

But personally, I'd just go through the pain of enlarging the Camden
tunnels.

(Just don't expect any of this to actually happen. *We are talking
about the UK DfT!)

True, but given that all major parties are in favour, it's actually
got a decent shot.
