At first this rolling stock was only used in the Netherlands by Nederlandse Spoorwegen.
After privitasation in 1998 the ownership changed to “RailPro”, later renamed to “Voestalpine Railpro”. This company uses them for delivering ballast to several rail-construction-projects thoughout Europe. (https://youtu.be/6CBdZdcGpmI)
