Class 332 of Heathrow Express, seen at the West end of Hayes & Harlingdon, where the Heathrow line (mostly underground) branches off the Great Western Main Line.
This trainset has just entered the Heathrow "Down" track, slowing from 100 down to 50mph.
One can also spot the Heathrow "Up" track (stretching from the fly-over in the background), with the 2 Fast tracks (125mph) of the GWML in-between.
GWML Slow tracks (90-100mph) are located further right.
