I found a historical photo of this room showing 10-foot high machines with wires hanging by the mile from looms and schematic charts.
While it looks like ground level, everything here is one story above the actual earth.
When block glass shatters, it looks like ice.
The conveyorway that carried the sintering material to the mixing floor at the top of the plant.
One of the few man-sized exterior doors, seemingly with an original frame. Classic arching and beautiful textures–every inch of wall had me drooling. If this engine house was in a metropolitan area, it would have been turned into a $10 million white collar office suite ten years ago.
Cracked gauges have a certain quality that hearkens to movies, I think. One can imagine the gauges going off the scales before dramatically cracking, throwing glass right at the camera. This damage, however, is unfortunate vandalism.
In its later years, metal was welded over every door and window on the ground floor.
Near the lower portal of the tunnel, a manhole cover seals the electrical connection for the streetcar line. Twin Cities Lines is the predecessor for Twin Cities Rapid Transit.
Standing on the fence barricade that used to keep squatters out of the tunnel, the size of the space is impressive. What you see here is the current length of the tunnel; I set up a flashlight at the end to illuminate the concrete wall that is the lower portal.
