595 approaches Longford Mills where it will set out these four tankers of Ethylene Oxide at the Stepan Chemicals plant and lift four empties to return to Huntsville for pickup on tonight's 450. This section of track, approximately 5 miles south of Washago, dead-ends just south of this siding which serves the plant. It used to be part of the Newmarket Subdivision when that line continued south across the Atherley Narrows separating Lake Couchiching from Lake Simcoe, and down the west side of Lake Simcoe to Allandale. The sections from Allandale south to Toronto and Washago north to North Bay remain in service, but all through freight from the northern section now travels down the Bala Sub.
