About a third of Canadian Pacific Railway Ltd. ’s targeted revenue growth over the next four years will be driven by crude-by-rail shipments, as the railroad focuses on improving its oil-loading terminals and track in western Canada, the company’s chief operating officer said on Tuesday. Last week, Canadian Pacific unveiled a series of aggressive financial targets, including plans to double earnings per share by 2018 from the expected 2014 level and to hit revenue of 10 billion Canadian dollars ($9 billion). Analysts are projecting revenue of about C$6.6 billion for this year. One-third of that new revenue will come from Canadian Pacific’s crude-transport business, Chief Operating Office Keith Creel told The Wall Street Journal after delivering a speech here. “Our franchise is in a very strong position relative to that growth.” The company’s bet on oil-by-rail underscores the growing interdependence between the oil and rail industries as North American oil and gas production booms. The amount of crude moving by rail in Canada has quadrupled since 2012 and is expected to continue to surge. However, the practice has attracted concerns amid a number of fiery derailments, including one that killed 47 people in Quebec last year.
