No, I should have been clearer. The turntable that I am speaking about, which was used as late as the 1980s, was right at the VIA station in Halifax. It was still in use as late as 1987. It was, if you were in the station and facing the tracks, at the immediate left. It had been in use for many years as I understand. The Ocean was turned, car by car, on this turntable as it was being made up for departure. It was a bit tedious to watch. I imagine that the switching crew must have been very busy years ago when several trains a day, such as the Ocean, Scotian and the Maritime Express (shades of Hank Snow) had to be turned there in this fashion.
I believe the turntable at Fairview was the turntable for the CN engine terminal there. I do not believe that CN or VIA passenger trains were ever turned there on a regular basis. Corrections would be welcome.
