I wouldn't say the majority of cases are right due to the fact how much can be edited by some random person. Looking at GNE list of vehicles, I think only about 60% of depot allocations are right if I'm being generous.

I was trying to load up the Stagecoach Sunderland 8 timetable today to try and track 28002 for a photo but it kept sending me to the timetable for GNE service 8.

It's far from perfect but it's one of them things that will do.
