Go North East's Scania L94s for example couldn't be used - they've been fitted with an additional handbrake, an instructor's seat, and two coach seats for passengers (as well as tables on some of them). This means that they undergo a different type of MOT test (Class 5).

The white coaches in the Training Fleet haven't had any of these modifications done, so still see regular use on Private Hires etc.

However, at a company such as Arriva, ticket machine apparatus and assault screens would have been removed, in some cases, destination displays too. Also, I believe the mentor seating isn't removable either.

I'd say the answer would be no, and a vehicle would be loaned from another depot.
