Caption: In the dying light of a perfectly sunny and cold winters day, CN 4112 and 7029 pull four loads from the Gerdau Ameristeel plant in Whitby, Ontario. Arriving light from the yard in Oshawa and after a brief fight with the switch into the plant trackage off the South Service track, they darted into the plant yard, grabbed their lift, and retreated back to Oshawa. 1856hrs.

Wonder when this type of scene will be a thing of the past? With 50 plus years under their belts, he GP9 has surely outlived the iron horses that they replaced in the 1950's... a remarkable feat given the mileage they've racked up before and after remanufacture, and the fleets that have come and gone while they've kept toiling away with little fanfare.

CN 4112 started life as CN 4249 in 1958, so she isn't one of the oldest on the roster, however having been remanufactured into a GP9RM in 1984, she has actually toiled in this form longer than in her original high hooded configuration.

The trailing unit, CN 7029, was built as CN 4150 in 1959, renumbered to 4391 in 1984 to make room for the 4100 series GP9RM's (which never went above 4143). CN 4391 Finally went into PSC for conversion to a yard goat in 1991.
