A visit to British Columbia's Fraser and Thompson River Canyons guarantees one thing: A never-ending series of engineered solutions to overcome the challenges of constructing two water-level railroads through the narrow, steep canyons that the rivers cut through the Cascade Range. Located at Cisco is one of the classic examples these solutions, where CP (the first line to follow this route) punched a tunnel through an outcrop and then immediately jumped across to the Fraser River to its east bank. Arriving some two and a half decades later, CN predecessor Canadian Northern Railway was left with little choice but to also switch sides of the Fraser, which it accomplished via the steel arch bridge at right. Popping out of the aforementioned tunnel on this glorious summer morning is the trailing remote of a long eastbound CP stack train, taking advantage of the river-grade line and modern technology to move nearly two miles of containers with only three locomotives in a 1x1x1 DPU configuration.
