Does anyone here know what the conditions were like inside the cab of the last generation steam locomotives during nights like this? Was the cab buttoned up at all, or did the boiler give off enough heat to make it bearable? Were the shops heated? I can't imagine being able to heat the cavernous buildings in North Billerica. I only ask because I work mostly outside on the night shift and I can not fathom working in northern Maine with temperatures like they saw this week.
