The entire economy can’t just shut down because of some snow. Realisitically the most dangerous part about that weather is the driving, if we just built public transit, their commute wouldn’t even be that different from a sunny day. If you dress for the weather you’ll be fine.
Tell that to the danish public transit system shitting itself because we’re getting a bit of snow tonight. In reality, there’s a better chance of you being able to drive your car to work, than the train being able to go. Because your car isn’t bound by minimum speeds, but if the train can only go 10 mph because of snow and ice on the track, it’s just not feasible to run it.
That’s rough. I thought operating rail systems in inclement weather was a mostly solved problem.

Trains on rails have basically no traction, since the contact surfaces are steel on steel. Anything that makes them slippery becomes a no-go as soon as hills are involved, and stopping is also significantly impacted.

Having them not require tires is a solved problem, but as you can see that comes with some compromises.

They have grit dispensers for the wheels for this exact problem in snowy areas.
