It was sold to the Aluminum Company of Canada in 1940 but then ??.. have to assume it was scrapped at some point, probably sometime after it worked heavily in the war effort.
The R&S had several tank locomotives and this one, #15 was saved and is on display today.
Note the added on wooden sided tender. Actually I like the original older version appearance better.
