The Union Depot was a train station located in Lansing, MI. The Union Depot began passenger service for the Michigan Central and Pere Marquette Railroads in 1902. The Detroit architectural firm of Spier and Rohns, which planned many Michigan Central stations, designed the building with Chateauesque conical towers and cut stone arches. The depot closed in 1972. In 1999, two old passenger rail cars were renovated and attached to the building, adding more space and more atmosphere.
