Covered goods wagons are almost as old as the railway itself and mainly serve the transport of piece goods. In the 1950er, the Deutsche Reichsbahn (DDR) was only able to maintain the demand for these vehicles by retrofitting and modernizing older G-cars. In 1966, the RAW âUnityâ Leipzig began with the construction of a Glmms model car with silted sheet metal walls lined with wood on the inside. This type went into series production at the Gothaer wagon factory from 1968 and was called Glmms 14.05 (from 1977 as GBS 1500).The welded structure, with its distinctive side walls, reached down to the lower edge of the outer frame carrier and was connected to the box profiles. This meant that the conventional car body supports could be dispensed with. Most of the cars were built with reinforced doors. The floor was suitable for loading forklift trucks and consisted of pine beams.By 1983, more than 17,000 pieces of the GBS 1500 construction were produced. Among them various designs as heat protection and express goods wagon. Some types of substructure were equipped with brake platforms and heating lines. Due to the lack of production capacity in the own plants, cars were also built in Serbia, Romania and even Spain. The cars were used by the RIV, MC or OPW traffic for suitability beyond the national borders of the GDR and were thus often seen in freight trains of other railway administrations even before the turn of the century. After reunification, these wagons were still used in the DB AG stock until the late 1990er. The last were retired in 2007.This text is machine translated.
