History
Demonstrator DMU

The first DMU demonstrator (numbered 2002) was built in 2002.[2] The DMU was built to meet FRA's 49 CFR Part 238 compression load requirements, Which made it the first modern FRA compliant DMU in the United States. The DMU toured the US Between 2002–2004 to demonstrate the DMU to potential future operators.[3]

Revenue DMU Orders

In 2005, the first bi-level DMU would be built for Tri Rail as par of an order for 4 DMU units that would be built form 2005–2007.[4][5][6] TriMet in Portland ordered 3 DMUs and 1 cab car for use on its WES commuter rail line that were built in 2007–2008.[7] Alaska Railroad ordered 1 bi-level DMU that was built in 2008.[8][9]

Details

The DMU is powered by 2 Detroit Diesel engines with a combined horsepower of 1200. Each DMU is capable of traveling up to 100 mph. The DMU is 85 ft long with a height of 14 ft 10in(19 ft 6in for the bi-level DMU). The DMU has 92 seats (190 for the bi-level). DMUs can be ether single ended or double ended. The single level DMU has a streamlined cab at one end, and a flat cab on the other end(if the DMU is double ended). Bi-level DMUs are all flat cab units, but can have the roof of DMU slanted. DMUs can be fitted with dome widows or standard windows.[10]

Successor

In 2009, US Railcar took over Colorado Railcar after the company shut down. They intend to continue producing DMUs for the US market, but haven't received any orders as of 2023.[11]
