I was on a 165 from Aylesbury a few months ago, it musthave been a
refurbishment try-out, because a few of the opening windows had been
fitted with locks, and the rest removed, and replaced by a single
large shet of glass. You could still see in the frame where the
opening section had been. The SWT units from Waterloo to Exeter also
have only a few openable windows. Why should the number of windows
which can be opened for emergency ventilation in an air conditioned
vehicle be any less than the normally openable ones in a non air
conditioned vehicle?
I seem to remember that the Thames units (166?) have about as many
windows which can be opened as a 165.
