According to http://content.tfl.gov.uk/toilets-map.pdf there is a toilet at this station, but it is not currently mapped on OSM. It would be helpful if any editor who has to wait here could investigate its position and map it, together with a text description eg platform 2 and add access=customers if it's inside the ticket barriers, or access=yes if it's outside.

82 Southover, London N12 7HD was not showing the correct location on the map. Now the marker has been moved to show the correct location. Please update the records.

There's a note on this that says "note = converted into holiday accomodation" so presumably it's not actually a chapel any more and shoud not be tagged as a place of worship?
