I know Tube Lines were supposed to be close to ordering new trains to
replace the 1973 stock, but I wonder what the status is now. With Tube
Lines being absorbed by TfL, and a government freeze on any new mainline
train orders, would it be fair to assume that this replacement Tube
fleet won't be ordered for some years?

If so, what will need to be done to keep the 1973 stock in good working
order? Personally, I like the existing trains (yes, I agree with
Boltar), and wouldn't be unhappy seeing them soldier on for another ten
years, but don't know if there are any developing
mechanical/electrical/safety problems that could prevent this. And would
they need another refurbishment or heavy overhaul programme?

There's a big gap in age between this fleet and the next oldest (once
the A, C, D and 1967 stocks retire over the next few years) --
amazingly, with the demise of the short-lived 1983 stock, the
extended-life 1973 trains will be almost 20 years older than the next
oldest LU fleet on the Central Line.

There is a large number of trains from the mid 1990s, and another even
larger batch will arrive in the early Teens. LU does seem to take
delivery of trains in a very uneven way.

LU investment has happened in a very uneven way. Not too sure we've
seen the end of that pattern...

There will still be the 1972 stock on the Bakerloo, which is not
scheduled to be replaced until after the Piccadilly.

Good point, I'd forgotten about them. But they're actually newer than
the 1973 stock, aren't they?

No. They started going into service nearly two years earlier.

My memory is that the whole fleets of 1972 mark 1 and 1972 mark 2
stock were already running on the Northern line alongside 1938 stock
while the 1959 stock was just starting to be displaced by 1973 stock
being introduced on the Piccadilly, and moving over to replace the
rest of the 1938 stock (and the 1972 mark 2 stock eventually).

And my memory, FWIW, is that the 73 stock was introduced in about 1975,
not 1973.

Since tube stock seems to be good for at least 40 years' service, I don't
suppose the world would end if they delayed replacing the 73 for 5 years
(from now).

Yes it was. And the 1972 mark 2 first introduced in late 1973 (and
all in service by some time in 1974 according to a source I found
since).

A stock still going strong and will be very sadly missed. I sometimes
hear normals talking about the nice, comfortable train they caught
between Kings Cross and Baker Street or wherever. It's not just an
enthusiast thing.

LU stock seemed a lot more interchangeable then, swapping between
lines quite often. Nowadays it seems as if it's always purpose built
for a specific line and signalling system.

Some of this was touched on at high level by Mike Brown (LUL MD) when he
appeared in front of the GLA Transport Committee this week. There is a
webcast of the session on the GLA part of the London Mayor website.

The Picc Line Upgrade will be reviewed by LUL once the Tube Lines Share
Purchase deal goes through. This is largely because of the dependency
between the Jub, Northern and Picc upgrades in terms of signalling
contractor and thus a delay on one impacts the following ones. Mr Brown
did not, IIRC, specifically mention a time for the Picc Line trains but
it may well be that trains are ordered but run ahead of the signalling
works.

The other point Mr Brown made was that Tube Lines had done a good job in
maintaining the train fleets and that the Picc Line reliability was very
good and therefore the trains could probably keep running perfectly well
for a number of years. He did say the signalling was the key issue and
also that integration of the Picc and Sub Surface resignalling might
bring about synergies.

The key message is simply that we all have to wait and see what happens.

Island line is assumed to be getting 73s, as indicated by SWT comment in
their recent web chat.

If the 73s are not due to be replaced for a while, however, then are the
38s going to continue in service?
