If an LU train fails between stations and comes to a stand do following
trains successively apply the "stop and proceed" rule leading to an
enormous queue of trains with minimal distance between each one? Does
the train immediately behind the failed train shunt the failed train to
the next station and subsequently to the depot? Is it feasible that the
train behind the failure could be incompatible with the failed train in
which case what happens then?

It depends.

It all depends on what the problem is and how long it is likely to cause
the shut down. Usually, the controller will instruct following trains
to wait in platforms once he has been advised of the problem.

If the incident is going to take some time to deal with then some
trains will be reversed in the opposite direction to get them out of the
way. Trains following up further away may well be put away in depots
before they get anywhere near the scene. Any trains stuck in tunnels
will generally 'apply the rule' to get into a platform to allow
passengers to leave. This may involve a train stood in a platform
leaving empty and standing in the tunnel to allow a full train to enter.

There are a lot of options open to the Line Controllers and they will
make the decision what to do as the event unfolds.

As a last resort, the following train could be used to 'push out' the
failed train but that is very unlikely to happen as a fitter will be
brought down from a depot to deal with it where it is.
