Back in May of 2016, Stadler announced that they were building 10 new railcars for the luxury train service, based on the "Ultra Domes" that Colorado Railcars previously built. This will be the first time the company is building locomotive hauled passenger railcars for the North American market. I was surprised when they announced this, but the company has been known for building custom made rolling stock, EMU, DMU, and locomotives. Though it makes me wonder why they didn't go to US Railcar, the company that bought the assets of Colorado Railcar, who still advertise the "Ultra Dome" as one of their products. Here's the announcement in 2016:http://www.stadlerrail.com/en/meta/news-media/article/rocky-mountaineer-announces-partnership-stadler/ The website Railway Stays took recent photos in October of 2017 of the building of the new railcars in Germany.
