text: Agree -- its unnecessarily complicated. Looks like somebody has fallen into the trap of assuming roof sections correspond to buildings but it's probably all one building with no need to separate it. Unless there's an OSM editor on the bus company staff that can map inner divisions (based on actual walls, not roof sections), I'd suggest keeping just way 40404631 and deleting all the so-called buildings within it. The tag amenity=bus_garage is dubious -- bus stations serve the public but bus garages are usually private. Also check the edge along Sulgrave Road. The bing arial view along this side looks like residential housing to me.
