"The train traveled several miles" The speed limit at that point is probably 79 MPH, so it would take under 2 minutes to go "several miles." I suspect that given the reaction time of the motorman, the switching mistake (not a driver error) was probably discovered almost immediately, and the motorman followed policy and continued to the next station where the passengers could disembark. They probably "traveled several hundred feet" before they realized the towerman's mistake, is more like it.
It would be irresponsible for the motorman to panic and go into emergency braking once he realized that the track switches had routed him the wrong way. (It's not like he taxied off the end of a runway into a swamp.) Following trains could get fetched up and passengers would have no way to get off and get turned around, as apparently they were able to do without major inconvenience. Much more reasonable to continue to the next station, as I'm sure the dispatcher, who is always just a PTT microphone call away, advised the motorman to do.
Trains don't "get lost" nor do motormen have any choice in their routings. They go where the tracks lead them. Tower operators can set the interlocking incorrectly and the train will go where they tell it to go. Why are they suspending the crew, rather than the tower operator?
Someone should take a reporter to a locomotive shop and show him the steering wheel on a train. There is less to this story than the media would like us to believe. Oh wait...that's their job isn't it?
