The schools closing thing is a really thorny issue. However, the decision is not made lightly as schools are penalised if they shut and it is deemed unnecessary. It is more about the litigious society we now find ourselves in, risk adverse mangement teams and also the uncertainty that staff may be absent and conditions may worsen making it very difficult for children to be collected. Difficult situation for the parent/guardians though, as stated.
We had some bad winters in the late 50s/early 60s but the Grammar School I attended never closed even when the supply of solid fuel for the heating system was late delivered!
I used to cycle around 2.5 miles with a group of friends in all weathers and no one seemed to 'bat an eyelid' The attendance rate was always high and it was very rare for a Master not to be in attendance (dressed in Cap & Gown), OK the school was very strict, but we actually learnt a great deal, things that serve me well today still ( unlike some of the contestants on todays quiz shows who don't seem to have been taught very much!)
And we had a Model Railway Club as well!!
