New tonight amtrak trains on the northeast corridor are running on schedule again a day after a train hit a backhoe just outside of philadelphia. More than 30 passengers and the engineer were taken to hospitals after the collision which derailed the train. Now investigate rs are trying to learn why the backhoe was on the rails in the first place. Reporter its still unclear at this hour why that backhoe was on the tracks, but new york senator Chuck Schumer says it may have been clearing debris from the storm that night or was being used for regular maintenance since fewer trains run on sunday mornings. The train was heading from new york to savannah, georgia at about 8 00 a. M. On sunday when it hit a piece of equipment on the tracks. The impact derailed the lead engine of the train which was carrying more than 300 passengers and seven crew members. The People Killed was the equipment operator and u. S. Senator Chuck Schumer said the other was a supervisor and both were amtrak employees. The data recorder and video from the locomotive were recovered and the recorder was sent to the ntsb. Senator schumer says amtrak has a 20step protocol for having equipment on the tracks. Clearly it seems very likely to be human error. We all want to send out our prayers to the families of the men who lost their lives on the tracks here in chester yesterday. Amtrak workers, my understanding is that theyve been workers for quite some time, employed for quite some time by amtrak. Our prayers go out to their families and their loved ones. Our prayers also go out to the onratetor of the train operator of the train. That had to be a devastated and horrific event for him.
