It's encouraging that the old principle still seems to stand - put on a train at a place or time there was no train before, and generally people will start using that train.
"The old principle" better be backed up by studies showing real interest and demand for train service, otherwise we will see another Janesville, WI empty train. The state of VA spent a good deal of time working with Amtrak to determine what was needed, when it was needed and the extent of the demand. "Build it and they will come" does not work for any kind of transportation.
