The new bi-levels should free up the Amfleet Is and Superliner coach cars used in California and the Superliners that get used in winter in the Chicago corridors.
And I think it should free up the Horizons and Amfleet Is used in the Chicago corridors too! Well, eventually.
I haven't actually figured out what the state-for-state split is (they've been awfully vague about that). Thanks to the person who tracked down the RFP: It's 42 to Caltrans and 88 to "the Midwest Coalition" (no MI/MO/IL breakdown).
There are 96 Horizons, so the midwest order is not quite enough to replace the Horizon fleet. However, a whole bunch of those are used for the Hiawatha, and a couple for the soon-to-end Hoosier State. So I assume it's intended to replace everything except those. It still seems a bit tight, so I would expect them to take up some options just to have spares and room for expansion. Perhaps if they take the option, they'll get enough to use them for the Hiawathas too; Illinois does pay *part* of the cost of the Hiawathas. That would eliminate single-level cars from Amtrak in the Midwest (except for the long-distance trains heading east, obviously).
I assume California plans to keep the California Cars / Surfliners, replace the Amfleet set on the Surfliner and the ones on the San Joaquins, replace the 7 California-repaired Superliners, and replace the Comets they just bought. With an order of 42 this means they are already ordering enough for spares and more expansion.
Whoa. $551 (allocated) - $352 (bid) = 199 million. That is enough to get quite a lot of extra cars. Enough that some of the money might even be redirected to something else.
The freed-up Amfleets, Horizons, and Superliners will provide only a little relief; 7 coaches doesn't help the Superliner shortage much, and the acute single-level shortage is Amfleet IIs. (I wonder if Amtrak will convert some Amfleet Is to long-distance seating to alleviate the mid-term Amfleet II shortage.) That said, the Horizons are almost certainly going to end up on the NEC.
Here's hoping for a Viewliner Coach order in the new year, followed by a Superliner III order...
