You seem to know a lot about trains and snow. Tell me, how is it then that Sweden and Finland continue to have trains in the winter? Or Switzerland or upper Austria for that matter?
I don’t know a lot about trains and snow. All I know is what I’ve been told every time trains are cancelled here in Denmark because there’s snow on the tracks, or because a few leafs have landed on them.
But it doesn’t take all that much to realize that a very small contact area, with low friction materials, with a slippery surface inbetween makes trains a lot worse at both speeding up, and slowing down.
If train is late its not because of “few leafs”.
Wet, smushed leafs pack on the rails like film that slows down both acceleration and braking, because there is not friction, but there needs to be shit ton of them.
Ice effects supricingly little to acceleration/braking. Trains are so heavy that the pressure on the tracks melts the ice allmost instantly. Bigger problem is the snow, that starts to pack on parts of the train.
Id imagine big part why trains in Sweden and Finland stay on time is because train companies know trains move slower in certain times so they adjust the schedule accordingly.
