There is another photo on MichiganRailroads.com showing the MC coach yard between Vernor and Michigan from the steam era. The electric locomotives are clearly visible.
Before a fire destroyed the Third Street depot in 1912, the Canadian trains emerging from the Detroit side of the tunnel would have to be backed up almost a mile in order to arrive at Third Street.
If one looks very closely, one would see a very short segment of one track still remaining in the moat just west of Twelfth Street that still remains between the tunnel and the former Sixth Street yards. For some reason those few feet of track were never pulled.
