The line originated at Port Arthur in the east, ran through Fort William and onward to the Canada–United States border. The PADW was constructed with the intention of connecting to an affiliated railroad in Minnesota to provide a route to Duluth, however this section was not built.
The PADW was abandoned in sections, and fully closed in 1938.
