The B&O's South Chicago was located approximately at 94th Street and Commercial Avenue, slightly to the southwest of the Calumet River's opening to Lake Michigan. Additionally, the Pere Marquette Railway's "Night Express" to Muskegon and Grand Rapids, Michigan and its "Resort Special" to Bay View, Michigan, also used the B&OCT lines through the city, as well as the two stations on the approach to Grand Central Station. The B&O's 63rd Street Station, in the South Lynne section of the city was the company's other station within Chicago en route to Grand Central Station.
