I travelled on the Gospel Oak - Barking line earlier in the week, and
was annoyed by the fact that half of one of the windows was taken up by
a panel of some sort. Later I realised that this was an electronic
destination display, facing outward. Why is it on the window, when they
have a whole train to put it on? And why is it so big? The text display
is only a few inches tall, but the panel holding it literally occupies
half of the window. I later saw the same thing on the Caterham line and
on the East London Line, so sacrificing half a window for a few inches
of display seems to be the norm now. Do train designers even know what
windows are for?
