An Amtrak Piedmont passenger train collided with a tractor-trailer recently in Harrisburg, N.C. Thankfully, no one was injured.

I did find this tidbit in the Charlotte Observer coverage of the event enlightening:

The Piedmont, which runs each morning from Raleigh to Charlotte and returns each evening, was carrying 10 passengers, [Amtrak spokesman Cliff] Black said. Most were taken by taxi to Charlotte, but some were picked up by friends in Harrisburg. [Emphasis mine].

Just speculating here, but could devoting a large Amtrak train to a Raleigh-Charlotte route with so few passengers be … well … maybe a waste?
