Thanks for the update ehar, I worked at the Barrie rail yards 1977-1980 and although the roundhouse was gone we used the turntable on a regular basis except in winter when the pit was full of snow.
Contrary to what the below user says the Allandale Station has not been demolished, it has been restored. The building currently on the site is the same one that was there before the scaffolding went up, its just been returned to its as built 1905 appearance. If you're in the area go take a look, they did a great job.
as did my grandpa
My grandfather took this train to Barrie for his army training in WWII. He was dropped off right here at the lake.
