I think there's a brand new school building just in the northern end of the original school site here. http://www.bailygarner.co.uk/projects/moreland-primary-school/ I think it probably replaces the small buildings and playground mapped here, but not 100% sure.

needs survey.

Certainly the old school building is flattened. I've roughly placed a construction area for that http://www.openstreetmap.org/changeset/52495675 but that also could be surveyed more precisely.

Bing imagery is out of date here though

Suspicious. We're currently showing "Mayfair Market" and "Mercato Mayfair Market" right by eachother. Are these two nodes for the same thing?

Looking precisely in relation to indoor features of the station, I don't think there are gents only toilets here.

Without a level tag it's difficult to be sure though. So either these toilets are right here, and they need a level tag, or maybe...
I think they might have been put here roughly in the middle of the station a while ago, perhaps representing these ones which I've placed at least a bit more precisely: http://www.openstreetmap.org/node/5262929022#map=19/51.53126/-0.12456 ...maybe
