Amtrak did some analyzing and saw that there's a big demand for people traveling on the Cardinal to go beyond WAS and into the NEC. I don't have the numbers, but it was quite the difference. Lots of passengers don't like to transfer. I had lunch with a lady who lives in Wilmington and takes the train to Chicago quite a bit. She said she only takes the Cardinal because it is the only direct train between Chicago and the cities between WAS and NYP. I even asked about taking the much faster Capitol Ltd with a quick transfer in WAS. She simply stated that she hates transferring. I know this is anecdotal, but there are others just like this. You describe a cross platform transfer, but thats just inefficient. You may as well have them take an already busy Regional. Amtrak is not going to have a cross platform transfer for a train that runs only three days a week just so they can give the Cardinal Superliner equipment. You may as well just run the cars all the way to NYP and collect the extra sleeping car revenue to boot.How does it get WAY more revenue, why not run an extension train with a cross platform transfer, not unlike the BOS 448/449 stub, but with a proper dining car for meals
I wouldn't mind see through cars added to the Capitol Ltd. to go down to Florida or something.
