SLSF #1017 4-6-2 leaving Tower Grove (St. Louis, Missouri) station with the Sunnyland from Memphis in the early 1940s (C.E. Prusia). The Pacific type locomotive has the northbound Sunnyland, train #808, in tow at Grand Ave and will soon arrive at St Louis Union Station. The number on the semaphore instrument case gives away the location. The Chouteau Ave Viaduct is visible in the background.
