In 1905 and 1906, Jung delivered three two-axle rack locomotives to the Société Anonyme d'Ougrée-Marihaye in Belguim that operated coal mines and steel works. The two locomotives built in 1905 had the works numbers 844 and 845, while the one built in the following year was number 928. They had an inclined boiler and operated the adhesion and Riggenbach rack drive with a crank axle. The power output was specified as 130 hp. All three were withdrawn around 1930.
