Turcot roundhouse was not such a bad place to work. I never did but knew folks who did. As a teen-ager in the 50′s I often wandered around the circle looking at the steam locomotives in their stalls. The coal smoke was dirty but not all that noxious, and was liberally mixed with steam, damp but not dirty. Smokestacks above the locomotive chimneys at each stall took the smoke out and above. Hundreds of men worked their whole careers there (plus women in non-traditional jobs during World War 2), and thrived.
