Diesel-electric locomotives based on the EMD F40PH design as well as the MP36PH-3C are popular as motive power for commuter trains. Manufacturers of coaches include Bombardier, Kawasaki, Nippon Sharyo, and Hyundai Rotem. A few systems use diesel multiple unit vehicles, including WES Commuter Rail near Portland and Austin's Capital MetroRail. These systems use vehicles supplied by Stadler Rail or US Railcar (formerly Colorado Railcar).
