It would be very nice if the Cardinal can operate 7 days a week. I'm sure that many of the towns that it serves has little or no intercity bus service and people could use the train to travel to doctor's appointments in other towns along the route as well as maybe for business conferences in either DC, Charlottesville, Charleston, etc. I believe that on the Buckingham Branch, speeds were raised between Orange and Charlottesville so hopefully that has helped bring down the travel time somewhat.
In the end, unless if you really need to be in Charlottesville way before dinnertime, you are better off taking the Northeast Regional or the Crescent.
Morgantown is an hour and twenty minutes from Pittsburgh. I'm not sure if somebody would want to involve the Cardinal for their trip to Morgantown as it is too far north of the Cardinal route.
