@rvm The station's most distinctive architectural feature lay not inside but was the office tower rising above the station proper. Rumored as a possible hotel, it actually housed offices. The lower floors had marble lined corridors while the upper floors were bare. The top floor was never finished, its walls never being plastered over. Architecturally this mass was joined to the station with a band or pilasters running around the upper floors. The total composition included 18 levels above ground. A massive basement level provided facilities for baggage and mail. http://www.forgottendetroit.com/mcs/history.html
