That route was served by what we now call the Cardinal. It's a long history, but the basic gist is this:
-The train was known at times as James Whitcomb Riley and the George Washington.

-The train, like today's Empire Builder, started from two separate locations: Newport News and Washington/New York. When they reached Charlottesville, the trains were combined into one for the journey to Chicago.
-The route from Charlottesville to Richmond to Newport News, via Gordonsville, Mineral, and Doswell, is now owned by CSX and leased/operated/dispatched by the
Buckingham Branch Railroad, and is in very, VERY rough shape, especially east of Gordonsville (but still sees a good amount of freight traffic).
-The auto train detoured over the Richmond-Mineral-Gordonsville stretch a few years ago when there was a derailment in Fredericksburg.
-All reports I've seen say that the route is in too rough shape to support a time-competitive passenger route these days, but the recent attention to a new Charlottesville-Washington-New York service has raised awareness of the line, but again, the BBR would need to make some major infrastructure improvements first.
