I need to understand what constitutes the different classes of Trolley bus. What differentiates the classes. Of course, this is going to take some detective work and many hours of dedicated research!!!! Goody, goody. Anyway, the first obvious differentiating feature is the box on the top of some TBus’s. Looks like an air conditioning unit. Humm. Needs further investigation.
And of course there are the more obvious differences….badges. Poor images I know, will do better next time!!! The search for differences continues.
Livery is another differentiating feature. Red, purple, orange, green and blue have been recorded so far. And different designs.
