在加拿大的铁路运输中,煤的运量和运费都超过其它商品,每年煤的铁路运量超过3000万 t,运费高达6亿美元。虽然加拿大的铁路—水路联运系统得利于大装载量的单元列车和船舶,但煤从加拿大西部煤矿运到安大略(Ontario)南部的电厂,经如此长距离的运输还是很不便的。美国宾夕法尼亚和西弗吉尼亚生产的煤,具有靠近安大略南部的优势,因而煤的成本较低。由铁路—水路联运系统把加拿大西部煤经过安大略的桑德湾运到安大略海德罗的南提科克电厂,每吨统一运费大约为40美元,相当于长期合同供煤价格的50%～60%,比 In Canada’s rail transport, coal has more freight and freight than other commodities, with more than 30 million tons of coal per year and shipping costs of up to 600 million U.S. dollars. Although Canada’s rail-water transport system benefits large-capacity unit trains and ships, transportation of coal from western Canada coal mines to power plants in southern Ontario is inconvenient. Coal produced in Pennsylvania and West Virginia in the United States has the advantage of being located in the southern part of Ontario, so the cost of coal is lower. By way of the rail-water intermodal system, Western Canada coal is shipped to Sandy Bay, Ontario, via the Ontario Bay, to the Nantikesk power plant in Heydrow, Ontario. The combined freight rate per tonne is about US $ 40, which is equivalent to 50% to 60% of the long- ,ratio
