The Chicago and North Western Railway Power House is the historic power house which served the 1911 Chicago and North Western Terminal in Chicago, Illinois. The building was designed by Frost & Granger in 1909; it was mainly designed in the Beaux Arts style but also exhibits elements of the Italian Renaissance Revival style. Construction on the building finished in 1911, the same year the terminal opened. The irregularly shaped building borders Clinton Street, Milwaukee Avenue, Lake Street, and the former Chicago and North Western tracks, which are now used by Metra. The power house was built in cream brick with terra cotta trim, cornices, and ornamentation; the corner of the house at Clinton and Milwaukee features a 227ft brick smokestack. The building contained four rooms, a large engine room and boiler room and a smaller engineer’s office and reception room. The Chicago Tribune reported in 1948 that the power house output enough power to serve a city of 15,000 people. The power house ceased to serve the station in the 1960s, but when the terminal was demolished and replaced by Ogilvie Transportation Center in 1984, the power house survived. It is one of two remaining railroad power houses in Chicago and the only remaining power house for the Chicago and North Western.
