As I said in my other post, I think this will continue the problems at
some Circle/H&C/Met stations. The Liverpool Street to Moorgate portion of
my trips often involves a lot of guesswork about where the end car will
stop at.

So don't wait for the end car!

It's the one nearest the subway at Moorgate for the interchange. If one is
fiollowing the advice to board the part of the train nearest the exit at the
destination, as so many crowd control notices over the years say, it helps
if there is only one such place to get that part.

More pertinantly the westbound platform at Liverpool Street gets badly
crowded as it is - being able to use the full length with confidence would
help.

I overheard one of the TfL chaps (there was a huge posse there - there was
a deaf guy and a guy in wheelchair there, so maybe some kind of visit by
disabled people to inspect the new trains) mention a cunning design
featu the open buttons on the outside of the doors are at the edge, not
in the middle, which leads people who want to get on to move to the side
of the doorway, thus letting passengers off the train first, as the saying
goes.

Anyone who thinks this has clearly never seen a national rail service with
the buttons at the side at a busy station. It makes little difference where
the buttons are located.
