Do LU have any platforms shared by trains which do not have the same
number of cars in a set? Do such platforms have BR/Network Rail-style
stop markers or are LU train operators required to "judge" their
stopping point appropriate to their train length.

Yes, quite a few. There are markers, but they are attached to the
sleepers rather than at driver height.

Some examples I can think of:

The section shared by the Hammermith/Circle C stock (six cars) and the
Metropolitan A stock (eight cars).

The Wimbledon branch, shared by D stock (six longer cars) and C stock
(from Edgware Road).

Between Ealing Common and Barons Court the District trains are longer
than the Piccadilly.

Between Rayners Lane and Uxbridge, the Metropolitan trains are longer
than the Piccadilly.

At Finchley Road and Wembley Park, the Metropolitan trains are longer
than the Jubilee.

On the south side of the Circle, the District trains are longer than
the Circle.

In many outside sections, the platforms happen to be longer than the
trains anyway, and markers are needed so that they stay at the
entrance end. Thinking about it, this may be the case for nearly all
outside stations.

Yes!
Metropolitan (8) shares with Circle and Hammersmith & City (6) and also
with Piccadilly (6). Bakerloo (7) shares with Overground (?).

I think all of the lines mentioned rely on platform-mounted monitors
and mirrors for checking the doors (save Overground, which has
guards), and the train also needs to be lined up with the Correct Side
Door Enable transmitter, so the driver doesn't have a lot of choice in
where they stop.

Trouble is numbers don't help much, because of the different car
lengths.

If there's a standardish length of about 16 m (eg Circle, Central,
Bakerloo, Metropolitan etc), the Jubilee, Northern and Piccadilly are
a bit longer (about 17½ m), and the District D stock are longer still
(over 18 m), such that six D stock cars are about the length of seven
standardish cars. The "Overground" cars are about 20 m, so three of
them are the length of four Bakerloos.

Another location I forgot is Mile End where District (6 long, ie the
same as 7 standardish) use different tracks but same island platforms
as Central (8 standardish).

True, although the markers go back much further. I can't remember
that sort of detail before the 1970s unfortunately, but the sleeper
markers were well established then. I wonder if someone has early
pictures?

I thought that the Door Enable Transmitter was exclusive to the Jubilee
Line, because it let the driver know that he is properly lined up with the
doors. Other llines only had markers letting drivers know that they had
properly berthed.

BTW, isn't the diamond on the platform the spot that allows optimal viewing
of the mirrors?

Richmond/Gunnersbury is shared by District and 3-car 313s(?) (ex National
Rail now London Overground). Do those stations have both NR and LT
markers? Are they going to change the markers on the rest of Overground?

Usually! - On lines with CSDE (Correct Side Door Enable) fitted, like
the District, Picc,Met, C&H etc there are stopping diamonds in the 4
foot. Where stocks of varying length are operated and they stop in
different places, like Kings Cross St. Pancras WB then there are
numbers (length of train) or letters (stock).

Unlike on NR many stations only have one set of OPO equipment per
platform so sometimes the rear of the train would be far from the
platform entrance, whereas on NR there would be a stopping mark for
shorter trains. An example is Southfields EB; the last car of a D
Stock train is at the bottom of the stairs, but the last car of a C
Stock is further along the platform!

On the Northern and Jubilee they use a a system called Acurate Stop
(or something like that- it's a newer version of CSDE). The aim is to
stop in the green bar within yellow and black stripes, which is at
head height on the platform or tunnel wall.
