It ran from Opeongo Lake to Whitney, where it connected to the Canada Atlantic Railway (CAR), running a total distance of about 14 miles (23 km).
[1] The mill was a major stop on the CAR,[a] with an extensive switch yard extending on the south side of town along the east bank of Galeairy Lake.

In 1933 the CAR was severed between Two Rivers and Algonquin Park Station when a trestle washed out, reportedly due to the construction of a beaver dam.
This gave the W&OR wye at Whitney a new life as the main turnaround point for trains on the eastern end of the CAR.
On the western side of Costello it turned north-northwest until ending at Sproule Bay, the southernmost point on Opeongo Lake.
