"An Amtrak train carrying 130 people got lost last week after it traveled too far backward while turning around and ended up on local tracks in the suburbs of Philadelphia."
"In an attempt to complete its trip, the train had to turn around so that the locomotive in the back could be at the front,"
"The incident happened mid-day on Thursday of last week. As a precaution, the train's engineer and its crew were taken out of service, given tests for drugs and alcohol and additional training before being allowed to return to work this week. The drug and alcohol tests came back clean, Shulz said."
