My city used to have the Robin's Donuts Bus and the Taco Time Bus. They were wrapped for a couple years. They aren't anymore.
Old livery for Port Arthur Transit buses:
Trolleys, used from 1948 to 1972
The white and green with yellow western text paint job that they used after Thunder Bay was formed in 1970. They had this for only two years. The diesel buses used this into the mid 1980s, when they switched to the supercool dashy stripe. You can see one of the fishbowls on the left.
Several of the trolleys have been preserved and are sitting at the bus barns, no one really knows what to do with them. I think they should put them on a tourist line on the waterfront once the development there is finished. They're not wheelchair accessible but they're part of our history and nice to look at.

A Port Arthur Transit bus at the interchange area in Intercity. Whenever the two cities got into a fight, they'd stop interlining buses between each other so you would have to get off of one system and onto the other here.
For much of their history, each city had a route that went to the other city without having to transfer. The route, Mainline, still exists today, and is based on streetcar lines from 1892.
