The New York Central's acquisition of the Michigan Central in the late 1800s brought with it the MC's lines in Ontario, technically the Canada Southern but operated as part of the larger New York Central System. Thus some of the system's heavier power — including class H7 Mikados, J1 Hudsons and an occasional L2 Mohawk — operated between Windsor, Ontario and Buffalo or Niagara Falls, New York. In this wintry 1950s view from the collection of Tom Rock of T.D.R. Productions, an unidentified J1 Hudson backs through trackage in Windsor that was also electrified (note the outer third rail) for the electric locomotives that hauled all trains through the Detroit River tunnel.
