I'd of course prefer a 3rd Rail one as it would best capture the details, but I might consider a Lionel version if they did it first. The biggest challenge is getting the licensing agreement with Siemens. Bachmann has an agreement for the SC-44 model in HO and it is not clear if they also have it available for O scale.
GGD has scale Viewliners and Amfleets going on the water in the next few weeks for August delivery. Can't wait to see them in person and an ALC-42 would be nice to lead those cars as Amtrak's long distance locomotive of the future.
