As you may or may not know, the potential exists for a major snowstorm to affect the Northeast Corridor and Keystone Corridor this Friday and Saturday. Some forecasts (which may be overhyped) call for blizzard conditions and 1-2 feet of snow. How does Amtrak deal with this type of weather? I have a trip scheduled from Elizabethtown, PA to New York Saturday, returning Sunday afternoon. Should I be concerned?
