hour. matthew wald, i want to get back to you. the gentleman who was talking about this particular area where this crash happened it appears to be a rail yard. not sure if that tells us anything but is there anything that they should read into that? >> trains can derail if there is a switch misaligned. if it's a rail yard there are switches but it's not really clear what's happening here. >> how tough will it be for it to match this manifest list? obviously they know everybody on board the train because it's all computerized now. most of the people on board.dep stopped. >> they may have more identity information. if you paid with a credit card. if you're a member of amtrak --
