Shows cars being pushed over the crest of the hump at Proviso Yard. The building in the center is the general yardmaster's station. There are various hump signals that extend all he way to North Avenue. Two of these signals are shown just to the left of the yardmaster's station. In the foreground are tracks 24, 25, and 26 (26 is barely discernible). Note the broken ties along the right-hand side of the picture, and various trees and weeds which obscure positions of the track. Constant lookout is imperative at all times.
