Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 9, p. 132. Baldwin works number was 4703 in July 1879.
The QMO & O began service in 1877 as it connected Quebec City, Montreal, and the western Quebec town of Hull. It never made money and was sold on 17 May 1882 to the Canadian Pacific. This little Forney suburban locomotive was renumbered four times by the CPR and was finally relegated to yard service until it was scrapped in 1910.
The CPR paid handsomely - $Can7.6 million plus $250,000 for construction of the Quesbec Bridge. Still, according to a 1914 survey of provincial expenditures on railways (in [Sir Arthur George] Doughty and [Adam] Shortt Canada and its Provinces (Vol 17-18), 1914 ). Doughty and Shortt found that for the period 1874 to 1913, Quebec put about half of its Can$26.8 million into building the QMO&O or $Can14 million. Moreover, when the CPR acquired the line, it formed "...practically the main line of that company's road from Quebec to Montreal and from Montreal to Ottawa on the Quebec side of the Ottawa River." (pp. 240-241).
