After bus 112, a 1977 GMC model, was refurbished and put back into service, it showcased Oshawa's heritage on its interior and exterior. Various historic photograph reproductions were displayed on the interior with a historical mural painted on the exterior of the bus. Sound speakers and a radio were installed inside the bus and during its service, mostly along the 1 Simcoe route, it played the broadcast from Oshawa's CKGE-FM, known as Magic@94.9 at that time. The "1 Simcoe" (and later 1 Simcoe South/1 Simcoe North) route was the main north-south line (2 King and 2 Bond was the main East-West line). After retirement, bus 112 was displayed on the front yard of the Oshawa Transit garage as the Mural Bus, where it stood until sometime in mid to late 2012 before being removed from the property.
