[Talk-transit] Weird stations in the UK (as shown on Google maps)

[Frankie Roberto]

Hi Peter,

Nice work!

Just goes to show some of the advantages of OSM - we can fix the data
relatively quickly.

Incidentally, according to Wikipedia Bank and Monument tube stations are
treated operationally as one complex (see
http://en.wikipedia.org/wiki/Bank_and_Monument_stations), however on Google
Maps they are shown separately:
http://maps.google.com/maps?ie=UTF8&ll=51.511694,-0.08656&spn=0.005649,0.024462&z=16

When tagging, I think we should generally follow the 'rule of ground' and
tag what people perceive to be separate stations (eg most people would think
of St Pancras as a single station).
