This Louisville & Nashville freight with GE U-boat no. 1600 on the point is on joint C&O/Belt Railway of Chicago trackage traveling west, paralleled at right by the Wabash (now Norfolk & Western) main. The tracks in the foreground belong to the Baltimore & Ohio, with the former Pennsylvania (by now Penn Central) under the lead locomotive. Note the semaphores on the joint C&O/BRC tracks.
