File contains photographs featuring the tramline at Cassiar which ran from the crushing plant at the mountain mine to the plantsite in the valley (a drop of 427 meters). The first ore was originally transported by truck to the plant until the gravity chute was built in 1953. This chute was replaced with the first aerial tramline model in 1956, which was succeeded by the second model in 1975. This file also includes one photo of the original gravity chute, and one photo depicting a tramline worker.

Additionally there is a collection of eighteen photographs of tramline cars that were being surveyed for damage and condition, and another collection of six photographs of tramline study. The results of this study determined that there was variances in load sizes of the buckets caused by extra material falling off the panfeeder.
