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.

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.
