In 1930, Ferrocarriles de Montaña a Grandes Pendientes S.A. (FMGP) commissioned the company Construcciones Metálicas del Llobregat to build two low-side wagons for the Ribes - Núria rack railway line, which was about to be inaugurated. They were coupled to passenger trains and were used for the transport of small goods and also the equipment of skiers who were going to practice snow sports.
In 1957, when the Montserrat line was closed, the L-43 wagon, which only had a parking brake, was transferred to the Núria line. Built in 1892 by the Societé Industrielle Suisse (SIG), it was used exclusively by work trains. When the Generalitat of Catalonia took over the Núria line in 1984, the L44 and L45 wagons were rebuilt and metal-sheathed, but with the conversion of some passenger cars into higher-capacity platforms, they were sidelined and used only sporadically. The L-44 wagon has been rebuilt in Móra la Nova and is currently exhibited within the facilities of the Cement Train in La Pobla de Lillet.
