Good catch on the discussion group, GM. Raisin, thanks for the research on the Carbit website. I called their phone number on the website and they are still in business despite the appearance of their facility.
BTW, I caught a mistake in my last post when I said Iowa Terminal. I meant of course Chicago Terminal. Iowa Terminal is an interesting little shortline that uses electric steeple cab locomotives in common carrier service to this day.
I wonder why Carbit dropped rail service in the mid-1980s? It always makes me wonder why an industry would deliberately reduce their shipping options. The trackwork in front of Carbit was always very interesting with a siding and spurs indicating a lot of shuffling around was needed to get cars into position.
Perhaps they gave up trying to work with the bankrupt Milwaukee Road in the 1980s or the caretaker Soo Line? I cannot recall a single, all-new industry that Soo Line attracted to any of the North Side lines they inherited.
