Empty coal cars, heading north. Power companies generate electricity with coal. Quite a bit used. Prior to the Sixties, lot of boilers were coal-fired for heating. Now, natural gas and LP are used. You will find a lot of LP tanks out in country. A lot of the Madison taxicabs run on LP.
Big Rig missed the turn, plowed over median strip. Misjudged how slippery the streets were. He had someone shovel him out.
This car missed a curve also, you can track his slide. When you see some of these accidents, you know conditions are bad and better drive carefully. New snow covers glare icy areas.
