If you're talking about replacing the N-S bilevel order with Simens single level cars similar to the Brightline order, then Amtrak has nothing to do with such a decision. The bi-levels were ordered by the states of Illinois, California, Michigan and Missouri for their state-supported trains. If they wish to end the contract with N-S and reorder with Simens, I supposed they can do that, although a large amount of the funding for this order was Stimulus funding which is due to expire soon. So far, all has been quiet as to what the states are going to do. California is using some of its own money for its part of the order, so I suppose they could place an order whenever they want to. Of course the bi-levels are designed for low-level boarding, while the Brightliners will utilize high-level platforms, so some changes will be necessary, since high-level platforms are practically non-existant west of the Northeast Corridor. So, I guess it could be done, but not overnight.
