Why not make the Capitol a Viewliner train with the new cars coming on line. It would make the Pittsburgh connection easier - if they find the funding for the new switch that's needed. It would also make it possible to extend the Capitol to Phila/NY.
Then make the Cardinal a daily train to Cincinnati with Superliner cars. That route really needs a SSL on it. Indiana can fund a daily Hoosier if they want to. Route miles saved would do a lot to offsetting the cost of a daily train as far as Cinci from DC. Then add multiple Thruway connection from Huntington and/or Cinci to central Ohio and Kentucky cities. It appears CSX is shifting traffic away from Cincinnati and with a lower speed might make it possible to use that as leverage to negotiate storage/servicing track in Cinci and the daily service on a shorter route. That still leaves three trains (counting the Pennsylvanian/CL connection) to serve through traffic from the NEC to Chicago.
Amtrak is only getting enough Viewliner II diners for existing single level long distance trans, unless the
Silver Star really is left permanently without a diner (and I don't believe that), and just enough sleepers to provide for the "extras" already needed. Moving some to the
Capitol Limited would take up cars needed elsewhere, and you would still have the problem of finding more Amfleet II coaches (where are they to come from?). Actually, why does the
Cardinal need Superliners worse than the
Capitol Limited does?
Truncating the
Cardinal at Cincinnati would seriously harm ridership; What about all the people currently traveling through Cincinnati and Indianapolis? You're not going to keep (most of) those passengers with a Thruway bus connection.
People are still pitting one train against another (the old "trains for me but none for thee" theme). That doesn't help the cause.
