By Tube if you want. You'll just get to Terminal 1 a few minutes
earlier than usual, with the T4 loop being out of use.

IIRC there is a replacement bus service from Hatton Cross. The nice people
at 020 7222 1234 will be able to tell you for certain.

Terminal 4 station closes from Friday 7 January, although some trains
will run non stop via the loop for turning purposes on that day as
required.

All trains will terminate at Hatton Cross Saturday 8 and Sunday 9
January. (Just how long does it take to scotch and clip a set of
points?) for enabling works for the closure.

From Monday 10 January a new timetable (TT40) will be in place for 20
months which means all trains will run direct to Heathrow 123

Sorry misread, saw it as needing to get to T4.

Still, the number is good for travel info.

You will still be able to get to Heathrow T123 station by Tube at all
normal times when the loop is closed. For terminal 4 there will be a
shuttle bus from Hatton Cross station.

Dangit. Won't be here to bash those crossovers.


From Monday 10 January a new timetable (TT40) will be in place
for 20 months which means all trains will run direct to Heathrow
123

I wonder if TT40 bears any resemblance to the pre-1986 timetable,
before the Heathrow loop even existed.

It seems unlikely. For a start, I think the Turnham Green service hours are
different now.

Are they running a special timetable prior to the closure in order to get
all the trains the same way around during the closure, or is there no such
thing as a 1973 stock being "the wrong way around"?

Presumably there isn't, as there is only a loop at one end of the line, so
on alternate journeys the stock will be in reverse formation.

Unfortunately, there is. When the stock was built, there was no such thing
as the T4 loop, and all the stock was built handed.

Fortunately the Aldwych branch still existed at the time, leading to a
quantity of double-cab units being built.

"Single ended" 73 stock can be either way round as the coupler is mechanical
only. Double ended units, i.e. those with a cab at both ends are handed and
therefore need to be the correct way round.

However for the sake of simplicity I suspect that all trains will be turned
so that the "A" end is at the west end.

They were primarily built to provided flexibility when a single ended cab
need to be withdrawn from service.

Single ended units come in A and D end variants (Even numbered ones are
A end and odd numbered ones are D). Double ended units have an A and a
D end cab.

A unit is three cars, hence two together make a train.

No I didn't. The HEx uses a totally different station in Heathrow.

Feltham has been rebuilt into a gateway station for Heathrow, with step
free access from the platform to the bus interchange. They used to run
two direct express bus services from the T123 and T4 (going where
their numbers suggest). The T123 was subsequently absorbed into another
service, and the T4 was abolished completely. Now to get from Feltham to
Heathrow T4 you either have to change buses at Hatton Cross or change
onto the HEx at the central terminal area - which is much further from
Feltham than terminal 4 is.

Extending the H25 would provide a real alternative, but instead they're
relying on a replacement bus service.

It isn't inconvenient now - I did it twice over the summer, and it was
fine. Bus goes to central bus station - forget the number, but it's
pretty self-explanatory when you're there. And the old bus service
never did serve T4, so you're no worse off than you were before. For

It might be obvious but not to me. What is the advantage of having all the
units the same way round during the closure of the loop?

I could understand if the loop was going to permanently closed, so that
route maps could also be displayed 'in the direction of travel', but not
while it will reopen as a loop.

It would still be possible to introduce handed in-car line guides with half

The H25:

* isn't very frequent (4ph weekdays, 2ph evenings and Sundays)
* uses small buses which don't have the extra luggage space of
airport
buses
* isn't very reliable and doesn't often run to timetable
* would provide a worse service on the rest of the route if it was
delayed around Heathrow
* is run by Tellings Golden Millar, the worst bus company in London

I wouldn't imagine BAA would touch it with a barge pole.

Basically, the problem arises because a 73ts will *NOT* couple A to A or D
to D.

Half of the single-ended units were built to face Heathrow whilst half were
built to face Cockfosters.

For example, you can have:
114-514-314 + 315-515-115 (D to A)
203-603-403 + 404-604-204 (A to D)
888-688-889 + 301-501-101 (D to A)

You can not have:-
114-515-314 + 312-512-112 (D to D)
895-694-894 + 892-692-893 (A to A)

By having all the units facing the right way (I've no idea if this is the
plan - Steve?!), as they were built to do, it guarantees that you have a
balance of A- and D-facing units, and generally makes it easy for the depot
staff because any unit can couple to any unit.

If you have some A-facing units facing Cockfosters and some facing Heathrow,
you have a situation where you can choose two units which are otherwise
correct for a train (i.e. a cab at each end) but which cannot couple to each
other. It is much simpler for depot staff if this situation is avoided.

The problem does not arise on the Northern or Central Lines because all
units can be coupled to each other. The reason this is not done on all stock
is because it requires the electrical wiring to be duplicated through the
coupling (couplers are either left or right handed, IYSWIM), which is more
expensive and more prone to failure.

It is not simply a matter of having line maps facing the right way, though
this is a useful spin-off as far as the passenger is concerned.

Yes, hence the occasional use of the loop on 7 January despite T4 being
closed.

The notice we have states that the Line Controller will arrange for
trains requiring to be turned to go round the loop.

Having done so myself last year to get to T3, I agree, but for T4 it's
not so good.

And the old bus service never did serve T4,

Yes it did, but not on the same route - there was the separate route T4.

so you're no worse off than you were before. For me, in South London,
it's my preferred way of going to Heathrow, although I doubt it's quicker
than the Tube!

For those parts of South London that aren't on the tube network but have
direct rail access to Waterloo (including Waterloo East) it is quicker
than the tube.

Yes you can, but can a detour that big be described as "convenient"?

I knew TGM were the worst bus company in SE London since taking over
Crystals, but I thought their SW London operations were much better run.
Have they slipped? Or was my impression wrong from the start?

What kind of buses do they normally use? Couldn't bigger buses be
substituted?

Is the traffic between T4 and Hatton Cross really that unpredictable?

4bph isn't bad for a Feltham service, but the route is quite short so
the frequency could quite easily be boosted.

I wouldn't imagine BAA would touch it with a barge pole.

The other logical alternative would be a Heathrow - Hatton Cross -
Feltham service that could be absorbed into route H25 when the
Piccaqdilly Line service is restored.

Do you mean like those abominations found on some other lines where the
way the line is drawn is relative to the side of the carriage its stuck

So you have that incredibly logical situation of trying to a find a

not
the same as having to figure out which way its facing as you well know.


Anyone should be able to glance at them and read
them in seconds. Otherwise they're useless.

Useless to people with the attention span of a goldfish, but useful
to
everyone else.

Maps exist as help. If they're too complex they're no help. So why
bother
with them? Besides , a line diagram is a simple bunch of lines. You
don't have
variations for the sake of it.

Do you think road junction signs should always have north at the top?
Do you
think the signs where a road leaves a roundabout should all point
left as
they do now, or should they point in a direction which denotes their
geographical direction?

Since when have road junctions signs been maps? They're direction
indicators!
You don't look at an A-Z at some roads and then expect a smaller
version to
appear on a road sign. Apples and oranges.

units can be coupled to each other. The reason this is not done on all
stock
is because it requires the electrical wiring to be duplicated through
the
coupling (couplers are either left or right handed, IYSWIM), which is
more
expensive and more prone to failure.

I've no idea how its actually done but couldn't they just be connected
with
seperate cables (instead of via the coupler), which twist in the middle
so
to match up with the other unit?

eg:

A --- ----B
