Hi All.

Just a quick question - does anyone know what a small illuminated 'J' might
be used for on the northbound met platform at Finchley Road station. It
looks a bit like that light that goes on then off as the train passes over
the little arm at the side of the track.

Also, what's the problem with opening both sets of doors at stations like
Uxbridge, Golders Green etc., where there are platforms on both side of the
train.

Thanks in advance!
