The D10 was famous for being tough, reliable, and capable everywhere on the CPR system. They were light enough for short bridges and lightly built prairie or maritime branch lines, but strong enough to haul moderate freight and small passenger consists. Crews liked their sure-footedness, minimal maintenance headaches, and good steaming. They became the CPR’s “everywhere locomotive,” commonly handling mixed trains, rural passenger service, commuter trips, and local freights right up to dieselization.
