Work wagons have always been indispensable for the railway company.They were used, for example, on every working site, how ever small, to transport construction materials such as crushed stone or tools. However, as no money could be earned with these so-called X-wagons by the transport of goods for third parties, the intent from the beginning was to find cheap solutions for the procurement of work wagons. A solution that offered itself for this purpose was to refurbish wagons of older types by modification and to adapt them to the new requirements. Due to the continuously changing demand and the decommissioning of worn wagons, the number of the X-wagons strongly fluctuated time and again between around 48,500 (1920), 25,000 (1930), 41,500 (1943) and 15,000 (1953).The Xr-35 type selected by BRAWA is based on Gms-30 type wagons that lost their wagon bodies in the early 50s, or already before due to damage suffered during the war. The remaining undercarriages were equipped with new, stable side panels, thus adapting the wagons to the changed task areas.
