It also does sound as if the RGT, with all
brakes isolated, an not even a hand brake capable of being operated by
those on board, was simply coupled to another train, and hauled up the
gradient towards East Finchley, but I find it difficult to believe
that this was actually done.

It does sound like it. The Prohibition Notice [1]

seems like a sensible response to this by the RI. I find it
difficult to believe that anyone considered this a safe system of
work, particularly on what is ISTR a considerable gradient.
