These large Hydrocracker Reactors were build in Japan for the oil sands of Fort McMurray, AB. Consequently CN ran a special train, CN 351 from Thunder Bay with the five reactors separated by five ballast hoppers/gondolas, limited to 25mph due to W9 restrictions (wide load). In Saskatoon, the train was parked @ Nutana siding (major industrial park), before being picked up by the yard engines (two GP40-2s) for the remaining three miles to the yard.
