sometimes the rail cracks under the train. it does happen. steve, we re going to continue our coverage of this. thank you for being with us and helping us understand this. steve ditmeyer, former administrator of the federal railroad administration. let s bring you up to speed with what you re looking at now. pictures of i-5 in washington state. very close to tacoma. an amtrak train you re looking at derailed. this is the town of dupont. part of it, as you can see, has fallen on to the road. state officials say all lanes, all southbound lanes of i-5 are blocked near mounts road. this is in pierce county. we have crews on the way to the scene. there was a reporter on the train. he s from king. he says that there were dozens of people on board the train. again, we re trying to figure out whether this is the first train of a the first day of a new route or the last day of an old route because they were doing a switchover on the route.
