In 1998, Amtrak also purchased an additional Series VI trainset as a demonstrator for potential service between Los Angeles and Las Vegas. This trainset was built with two additional "coach class" coaches, for a total of 14 cars. The demonstration route was not funded and WSDOT purchased the trainset in 2004 to expand service. The purchase also allowed Amtrak and WSDOT to redistribute the "coach class" coaches. By using the two additional coaches from this new trainset and placing the two coaches from the spare set into regular service, the agencies were able to create four 13-car trains and one 12-car train.
