"Railroading" on the Alberta Coal Branch was always unique because of its location. It was a frustrating line to operate because of curves and grades...
Fifteen miles an hour was the permissive speed for freight trains. Not until 1927 did the Santa Fe's arrive to replace the Grand Trunk 400's. Trains were short but frequent. Train crews rarely lacked work in the days when coal was king, but the work wasn't easy. They were railroading in high country.
