Nipigon, often written as Nepigon in the 1800s, was located at Milepost 77.9. It was the major stop on the line between Jellicoe and Port Arthur, sporting a large siding (71 car capacity, which was later reduced), water tank, coal facilities, wye and station.
Canadian Northern had originally asked for running rights on the Canadian Pacific line between Port Arthur and Nipigon. When the request was denied, the company was forced to find a route for their line in an already difficult area. Between Red Rock and Nipigon, there was no other option than to build outboard of the Canadian Pacific, which was already hugging the western shore of the Nipigon River. A tremendous amount of money and effort was required to place the rock fill required to support the grade.
Once in Nipigon, the line had to cross part of the Nipigon River on a lengthy rock causeway, which required diverting a section of the river. This created a shallow area known as the “Lagoon,” which was separated from the rest of the river, with water circulating via one small bridge in the causeway. From there, it passed under the Canadian Pacific bridge over the river, and headed north toward Parmacheene Station.
There are photos of the construction of the grade south of Nipigon and a photo of the Nipigon Station in the following articles:
