Thanks, I had already planned to go and have a look at it next week. It's
been ages in construction.

Only a very few years ago, Greenford was a station with semaphore signals
and a wooden panelled escalator. Now they've both gone, but it's still one
of the very few stations with cross-platform interchange between DMUs and
automatic Tube trains.
