CA&E 425 is passing over Union Station in this undated photo. Trains going more or less straight would end up at the Wells Street Terminal, while the tracks in the background leading off to the right connected to the Loop “L” Van Buren. When Lower Wacker Drive was being built, this necessitated tearing down this second connection to thee Loop, and building a new one through the second floor of Wells Terminal. The switchover between the two took place in 1955.
