The Bluff City Electric Railway's car barn was located at 21st street in North Chicago. In his book "North Shore Line Memories," George Campbell mentions that this car barn was the last surviving structure that was used consecutively by the B.C.E.R, C&ME, and the CNS&M. I've done my best to locate the site at which the building once stood. The sprawl of Great Lakes and the general industrial decay in North Chicago make it hard to locate any old buildings definitively.
