When comparing the ridership numbers for the Cardinal and Sunset Limited to other LD trains, you need to compensate for the 3 days a week trips. In FY2014 (September, 2014 MPR), the Cardinal had 109,154 passengers. The daily CL has 235,924 passengers which sounds like more, but not on a per trip basis. If you multiply 109,154 times 7/3 to convert to a daily train base, the Cardinal would have 254,692 passengers. More than the CL and slightly more than the CONO for that matter. So the Cardinal does ok for ridership.I would agree with you on the Cardinal. It has the lowest ridership (just below the Sunset Limited) and by far the lowest revenue. Not to mention the two endpoints of the train, CHI and NYP are served by the Lake Shore Limited (LSL) and CHI and WAS are by the Capitol Limited (CL) with both the LSL and CL much faster. I have a personal beef with the Cardinal because Amtrak cut a train that served my local area twice in the last 20 years while keeping the Cardinal.
When the Viewliner II baggage-dorm and sleeper cars are finally delivered, the Cardinal will get a bump in revenue when a bag-dorm and a second sleeper car are added (year round for the 2nd sleeper). Whether the Cardinal gets a full service diner or maybe a Viewliner II diner car with a stripped down pre-made meal service remains to be seen.
You keep advocating the cutting of service so Amtrak can restore a TR/BL train through PHL to PGH to CHI. Why not simply advocate to your PA representatives and Senators and state officials that the TR/BL be restored, period? Amtrak's shortage of single level sleepers, diners, baggage cars will ease up when the 130 Viewliner IIs are delivered. The situation would be better if Amtrak were getting 5 to 10 additional sleepers and a couple more diner and bag-dorm cars with the CAF order, but it appears that the ship has sailed on exercising any of the options on the CAF contract.
