Located on Milwaukee and Clinton, the Powerhouse is the best-surviving building associated with the Chicago and North Western Railway. This was one of the city’s most prominent historic railroads. While a utilitarian building, this grandly-scaled example of the Beaux-Arts architectural style is noteworthy for its giant round-arched windows and fine cream-colored brick walls laid to resemble rusticated stone.  The powerhouse provided electricity and steam heat to the original terminal (now demolished), standing passenger cars, and other nearby railroad facilities for over 50 years.  It was designated a Chicago Landmark on January 11, 2006.
