Lynchburg. Not the Richmond - DC route. But I get your point. Sure, stuff falls on the track in bad storms, but generally they will not send a train through there's already a block up the track. If you are stuck, you can use bath rooms until they are filled (unlike cars). There's some food, and you can carry your own snacks in a bag on a train as easy as in your car. And, for the most part, there should be a tree trimming program. Bottom line, I think there's less likelihood of getting stuck on a train in bad conditions than in a car, especially in a part of the country that lacks enough equipment to clear the roads.
