Looks like something by DrChoi21 or AlexMaria, they have external sites and made Amfleet coaches like that. Like Metroliners. Not sure about the cab car though. Then, Magicland, PerRock, and xconnyx made Amfleet coaches. There are ways to get them all, except the Magicland ones with interiors, his DLS ones don't have transparent windows or interiors. Jeff Barr recently passed away according to his daughter Heather. The PerRock ones you can get on Amtrak Trainz Group via Wayback archive and the conny ones she reuploaded them again somewhere. Within the next few years Amtrak is retiring all the Amfleets and replacing them with new Siemens Airo trainsets which can run on diesel or electric. No more locomotive swaps at DC, etc..
