You are probably correct about the Bakerloo being 4+3, though I don't think
any LT trains in Central London (apart from the Aldwych branch) have run at
anything other than full length since WW2.

Short trains of tube stock have run since WW2:
Epping - Ongar (3-car)
Hainault to Woodford when it was a self-contained shuttle
Holborn - Aldwych
East London Line, during the period after ancient District stock was used
until A stock took over.
Acton Town - South Acton was worked by single car units of sub-surface
stock.

AIUI the A stock were always in 4-car sets and originally had operative
cabs at both ends. Until quite recently a few units were kept with
operative cabs at both ends, to work the Chesham branch diagram, and
they were also used in 4-car formation when they worked the East London
Line. But for many years most units have had an operative cab at one
end only, so have been used exclusively in 8-car formation.

My understanding is that the deactivation (in passenger service) of the
cabs at one end of most of the units happenned when the units were
converted to driver only operation. *In driver-and-guard operation, the
door controls were at the opposite end of the driving motor cars from
the cab, hence the single doors at that location (unlike the trailer
cars that have three double doors per side, none at the ends). *When
DOO was introduced, single units were no longer generally used other
than for the East London line and the Chesham shuttle, so apart from
the units used for those services, the units only had door controls
installed in one cab per unit, with the other cab coupled at the inner
end of a double set.

Tank you for the clarrification.

I think 4-car usage stopped by then on the mainline (ie, excluding the
Chesham shuttle and ELL). Uncoupling went out of fashion on LU by the
1980s.

Nevertheless, when the A stock was refurbished, most had only one cab
modernised with the other becoming disused. Some double-ended units, with
both cabs remaining usable, were created in similar fashion to the D stock
which is a mix, mainly of three car units with one cab at one end but with a
few units with driving cars at both ends.

While some of the double cab A stock units were used on the Chesham shuttle
and East London Line services, most were run as part of 8-car trains on the
Met main line. I saw one last time I was at King's Cross last week. I don't
think the double-cab D stock units have ever been run on their own in
passenger service.

ELL had short formations of Met F stock before the Q District stock took
over in the early 1960s until 1971.

The Olympia shuttle used four-car sets for a time in the 1950s if not later.

Acton Town - South Acton was worked by single car units of
sub-surface stock.

Uncoupling on tube lines continued after WW2. I think the last was the GNC
in the 1960s. If you include surface lines, uncoupling on the District
continued into the 1970s.

Not even when D stock looked after the ELL?

When I was a regular user many years ago, there were fasts to
Uxbridge, first stop from Baker Street was Rayners Lane. Morning
fasts non-stop Rayners Lane to Baker Street. My destination was Baker
Street but I think I remember that the fasts in both directions were
City trains.

Into the 1970s in the peaks Amersham and Chesham fasts ran non-stop from
Moor Park to Finchley Road, and there were Watfords fast from North Harrow
as well as the Uxbridges fast from Rayners Lane. All these ran to the City
(Amershams and Cheshams terminated in the long-lost bay at Liverpool
Street). There were a few Uxbridge stoppers which ran to Aldgate, but all
other stoppers terminated at Baker Street. Off-peak and weekends everything
terminated at Baker Street. Didn't they split and run as 4-cars off-peak?

Yes, I recall the short trains. The four car units had cabs at both
ends. The three car units had a cab at one end. Daytime services
were four car only.

Unless I misunderstood you, how could those trains have turned if they
only had a cab at one end?

They couldn't. Most tube stock was handed until fairly recently and could
only couple the right way round.

I don't remember that. When and for how long was D stock used there?

Please explain why a double ended unit needs to be turned especially
on a railway that would turn them with normal traffic anyway.

73 stock are made up of 2 3 car units making the 6 car train. Â*They are
handed; A ends and D ends (A are even numbers and D are odd numbers). Â*A
double ended unit can match with either but has to be coupled A to A or
D to D.

If one of the double enders that has been matched with a D end unit now
needs to be reformed to match with an A end unit it will need to be
turned first, hence the little trip to T4.

It is impressive to see how LUL saves depot space (?) by taking an
empty little train round a full trip, clearly wasting a lot of
electrical energy if I must say.
