Hello Greg, agree with you even the best crew on a flanger that was qualified for this section of the railroad I bet have their "oh crap moments"
At night I would think it would be a real challenge.
The videos I seen of the flangers the operator is positioned in front of the blade so he may be able to see things that required the blade to be raised before they get to it.
I think in these conditions over Donner Summit and other routes indicator signs would only be good until the snow got so deep and then they would become useless.
The force and weight and the amount of the snow coming out from under the flanger the signs better be well planted or the snow would knock them over.
Out there the snow is usually very wet and heavy. I am surprised how they run the Rotaries and the Flangers with the doors and windows open and the crewman do not look like their overly dressed.
Must have good heaters!!!!!
In the one post where they showed the snow plow going up and over the drift up in Canada someone made a comment about being on a flanger crew and said it wasn't much fun.
Like anything it takes practice and I am sure there are those @#$# moments.
As far as the items on top of the locomotive cab I was wondering if these are for breaking icicles inside of tunnels. They don't look very heavily built so it is just a guess.
I did notice thought that they are not very straight either like they may have been hit by something.
I have a hopper car that was made by Lionel that has girders on the inside that form a peak.
On the side of the hopper it has " Ice Breaker Use Only Use between Altoona and Cresson"
The marking on the side was the only reason I bought the car due to the fact I live close to this area.
Just some thoughts.
