I'm sure they do understand, hence the replacement bus service, and the
publicity of the works. Since Terminal 5 is happening, how would you
propose extending the Picadilly line to that terminal without an
enforced closure of parts of the line. Or would you rather the Terminal
passengers (when complete) are inconvenienced by poor rail links when
it opens, just so people wanting Terminal 4 aren't inconvenienced now.

What would you propose to do ?
Seeing this debate is really quite an eye opener. Whilst I worked on
the tube (late 60s & early 70s) there were no rail services of any kind
with very little complaint from punters, but now they've had a choice of
Heathrow express or the Piccadilly line for years suddenly there is
uproar because a little bit needs to be closed to improve access. What
petty minded those of you lucky enough to have public transport are.
