Santa Fe had a balloon loop at their Archer Avenue coach yard at Archer and Cermak. All of the other railroads’ trains were serviced at Chicago & Western Indiana’s service area at 51st St about 4 blocks west of State. There is a wye at about 39th St where trains could be turned.
All of the railroads at Dearborn except Santa Fe were part owners of the C&WI, which owned Dearborn.
Considering that Santa Fe didn’t have its own terminal, but was always a tenant at Dearborn Station, it had some of the best service facilities.
