Is it because of the TPWS (a safety system, look for
some metal grills between the rails), which would stop
them if they came in any faster than a crawl? A while
ago there were some posters at either Victoria or
Waterloo explaining it. I've heard announcements
pleading with people not to try to open the slam doors,
as the train would continue to crawl rather than stop
as might be expected.

So has this particular implementation of TPWS made the railway less safe?

The slam door problem will disapear soon anyway.

TPWS did mean that trains were having to accelerate towards the
buffers to make it all the way into the station.

TPWS in termini approaching buffer stops, whilct meaning the train
slows down once past the TPWS loops the Driver does tend to apply
power approaching the buffer stops, one thinks this is not a safe
practice as the whole point of the TPWS loops was to ensure the train
is approaching the buffers a safe speed at which it can stop without
hitting the buffers.
