Considering this article is about a Canadian train, used only in Canada, I don't see the point in using both unit systems. More so when the conversion between them does not work (i.e. the mileage per gallon versus the litres per 100 km). Moreover, Canada is using the metric system since the 1970's; therefore, the engineering specifications are probably in metric units as required by law. Anyways, that's my two cents on the issue. 75.98.19.140
