CPR Okanagan Sub - Turning Locomotives in Vernon?

Does anyone know how or if the CPR turned their locomotives in Vernon, BC? Was there a wye or turntable somewhere that has long since vanished? Did they use the wye in Lumby, the loop in Kelowna, or just run assend forward half the time?

I’m in the very early stages (dreaming and doodling) of a CN/CP Okanagan Subs layout (circa 1958/59), but this aspect is a bit of a puzzle at the moment.

Thanks in advance.
