Many Underground Stations are not named, Wood Street British Rail Station in Walthamstow is named Wood Green (actually a real place some miles to the West). Many other mainline railway stations are not named either. And those are the mistakes I have noticed after five minutes.

If this is the sort of mistake occurs on the map on which the Millenium Dome appears, and therefore a map which is likely to be a best seller, what else is the Survey getting wrong down there at Southampton (or has that now been renamed Northampton?)
