Do LU have any platforms shared by trains which do not have the same

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.
