Canadian Pacific’s experimental hydrogen-powered locomotive made its maiden revenue run last month in Calgary, Alberta, taking the first step in determining whether the technology could one day replace diesel-electric locomotives. The Oct. 28 revenue test run was the second main line foray this year for the unit, which uses hydrogen fuel cells and batteries to power its electric traction motors. Dubbed CP 1001, the locomotive pulled seven freight cars from a customer facility. By the end of next year, CP expects to have the three locomotives switching customers in Calgary, Edmonton, and Vancouver.
