Above, two postcard view of the Third Street Station in Detroit, serving the Michigan Central Railroad.  This was the MCRR's 2nd of three passenger stations in Detroit, and served from about 1850 until 1913 when the larger MCRR Depot was opened in a better position to access the Detroit-Windsor Tunnel.

Above, an 1854 engraving of the Michigan Central depot and roundhouse.  Below, an 1868 photo of the Michigan Central facilities along the Detroit River.  This photo looks north along the river.  The roundhouse is the doomed building in the center.  Behind it to the right in the back is the passenger station.  To the right, between the yard and the river is the MC freight house, which has transload facilities between rail and boats.  In these times, railroad freight cars were actually brought into the building to be unloaded.
