This was interesting.
Dropped off my daughter at the Exton, PA, Amtrak/SEPTA station this past Monday afternoon. A tree fell on the catenary and the eastbound train (headed into Philly) before hers got its pantograph entangled as well. All this occurred about 100 yards west of the station. My daughter's train was about an hour late and the passengers boarded the train from the other platform (for the westbound trains). Don't know how long the passengers were delayed on the stopped train.
