I think back in the 1950s and 60s everybody had a different mindset. Even a moderate amount of snow was enough to produce schedule disruptions, sometimes for days at a time. If you have access to a news archive search "snowstorms railroads" and I think you'll find I'm right.
Back then if we had a winter like this (though I don't remember our ever having one quite this extreme) people just assumed the trains would have problems.
As a taxpayer I don't want the powers that be to design railcars like tanks just in case we have the occasional rough winter, I really don't. To me it's a waste of money. I can live with the occasional delays and disruptions. I think most people feel the same way.
Next thing you know some genius is going to propose putting a dome over the entire Metropolitan Region so we're immune to the effects of Mother Nature.
I have no problem with staying home from work on 'snow days.'
