I just put my order in for a 5 car Superliner set with an add on coach and sleeper in Phase III. I am considering adding a set in Phase VI as well as I plan on getting a pair of P42s. Decisions, decisions!
After visiting the site I see the concerns on the reservation page. I will send a note to Scott after work letting him know to take down Phase I, and Phase V paint schemes. Amtrak does not officially recognize Phase IVb and calls the slightly lighter shade of dark blue with the Travelmark logo Phase VI in all of their documentation. Phase IVb is a modeler's construct.
For those who have placed orders, Shani will get back to you with a confirmation email and a PDF that shows your reservation.
