TPWS is set to intervene at 10mph+ (for a long time it was 5mph) but NR
increased the limit.

NR are talking about removing TPWS at buffer stops as it's not seen as
effective (strange that they were being told that before installation)

Most drivers will make sure the train is well below the 10 mph as
speedos on some trains are very hard to read at low speed (needle waving
all over the place) and if a driver triggers a TPWS loop there is a big
kerfuffle with having to report it to the controlling signaller, waiting
for permission to move and filling out paperwork. (Some of these
reporting rules are changing in Feb)

In the past few months I've noticed that many of the trains coming in
to platforms 9 to 12 at Victoria *crawl* all the way down the platform
before stopping. Anyone know why this is? It can't be some silly
safety issue because they accelerate out of the platforms normally,
and the same trains stopping at other stations - with crowded
platforms - come in quite fast and decelerate just like they always
have.
