The Stadler EuroDual (known as the Vossloh Euro Dual until 2015) is a series of dual power, electro-diesel locomotive by Stadler Rail Valencia. Unlike traditional dual mode locomotives, fitted with relatively low-powered diesel engines for 'last mile' movements only, vehicles are typically furnished with power units more comparable to that of mainline diesel locomotives.
The EuroDual series was launched by Vossloh during 2012, it shares a considerably large portion of its design with the single power Eurolight family of locomotives. Being customisable to meet customer demands, various sized powerplants can be fitted to the type; it can also be configured as a tri-mode vehicle via the installation of a battery pack. To date, there are three distinct versions of the EuroDual that have seen customer use; the UKDual for the United Kingdom, the PrasaDual for South Africa and an unbranded series for Germany. By late 2019, a total of 30 locomotives had been constructed, while a total of 74 Euro Duals were reportedly on the company's books.
