Yes, this is the Tunnel Company equipment that is preserved at IRM. The flatcars originally had pipe and chain fences for hauling merchandise from railroad freight terminals to department stores, etc. The other cars are ash cars. The locomotive and a number of cars were on an isolated stretch of tunnel at the Field Museum on the lakefront. The tunnel was breached during reconstruction of Lakeshore Drive and the equipment was removed at that time. Occasionally there is talk of making a short demonstration tunnel track, but I doubt this will ever amount to a working railroad.
