A Grand River Railway steel car crosses the King Street bridge over the Speed River as it approaches the Preston Junction Station in this colourized post card view. The car would have come from Galt and is likely enroute to Kitchener and Waterloo.

Built as a single track line along King Street in 1894, it was double tracked and centred on the street in 1914. Passenger cars operated along King Street from East Preston to Preston Junction, while freight trains travelled over a separate line between the same two points. Street running ended on August 27, 1939 when passenger service was moved onto the freight line. The time period for this photograph would thus be sometime between 1921, when the steel cars were purchased, and 1939.
