Canadian National long haul train M38531 (M385) is a daily mixed freight from Toronto MacMillan (Mac) Yard to Flat Rock, Michigan. Departure is early morning and the train often works yards along the route, depending upon demand and on line traffic congestion. Recently the normal workaday routine of M385 was interrupted; story line as follows.
Motive power assigned this day were six axle units CN 2195/2100/5423. Arriving at Aldershot Yard in Burlington the crew brought the train to a stop to assess over heating issues on trailing SD60 No. 5423. All modern units have on board diagnostic capabilities and built in safeguards were preventing the unit from loading (pulling). Electing not to swap out the faltering EMD and further to some ad hoc ‘McGyvering’, the crew managed to get the unit to load and set off to do battle with the nine mile climb that marks the beginning of CN’s Dundas subdivision. At 173 cars, some 11,553 feet of train, the struggle would be mighty; ten MPH overall would be a monumental achievement. This in fact would represent almost an hour of very hard pulling. Regrettably, No. 5423’s overheating gremblins returned, neutering the unit, making the SD60 unable to contribute to the task at hand. Just prior to reaching the half way point at mile four, No. 5423 shut down, bringing forward progress of the more than two mile long consist to a halt. Fortunately, Aldershot local train L55131 (L551) had not departed the yard, making available the assigned motive power; GP9RM’s, Nos. 4125 & 7068. The veteran duo would save the day, pushing M385 past the crest of the Niagara Escarpment (near Copetown), all the way to Brantford. What about L551’s assignment for the day? Delayed, and most likely performed by a different crew. The rescue crew would probably be short of hours to needed to carry out the local switching assignment. Same story for M385; depending upon their start time at Mac Yard, the crew may have run out of hours prior to crossing the border into the US at Sarnia. What about CN 5423? Most likely set out in Sarnia, the unit returned to Mac Yard for proper attention. By the end of the week the repaired unit had ventured as far afield as Moncton, New Brunswick.
