On April 18, 2015. The transit enthusiast group, Toronto Transportation Society, chartered two TTC buses, the RTS and Orion V for a farewell tour of the west end of the city. Both these units are due for retirement soon.
It's a good thing there is one of each that still exists today ex-ttc Orion V #9424 rests in a parking lot on along Hwy 400 between Finch & Steeles & ex-ttc Novabus RTS #7237 rests in a parking lot at the Police College near Islington & Lakeshore
This is unfortunately no longer the case for the RTS, as a quick look on Google Maps reveals that as of 2019 the bus was removed and a D40LF took it's place...
