Which makes me wonder why the rolling stock technician can't operate the
controls to fix the train himself! Did they not think of that?

A mobile RST would do so if the driver cannot clear the problem. A
control room technician cannot intervene directly - there is not a comms
system of sufficient quality on LU to allow that at present. Not sure if
the new Connect system could do so or whether the new Metronet stocks
will allow such intervention. I would have thought the better principle
is to build in reliability and redundancy into the trains to allow them
to keep moving even if a traction motor or some sub system fails.
