The Nationals canceled batting practice and players were allowed to show up at the ballpark later than usual because a chartered Amtrak train carrying the team home from New York derailed early Tuesday morning. No one was injured when the train went off-track as it slowed approaching the station at Wilmington, Del. "Nobody really knew what happened until the conductors told us that if we had been going any faster, the train could have flipped over," closer Chad Cordero said when he arrived at RFK Stadium for Washington's game against the Phillies.
