In 1945, RENFE ordered the first modern passenger cars of this type to modernize and improve long-distance passenger train services and to gradually replace wooden vehicles with metal-bodied ones. A total of 759 passenger cars, built by Spanish and French companies, served for nearly twenty years as the backbone of the modernization of RENFE's passenger service.
The CC 6029 and 6043 were 3rd class carriages, built in 1950 by La Charentaise and the Compagnie Industrielle de Matériel de Transport (CIMT) in France. In the late 1960s, third class gradually disappeared, and the carriages were adapted as second class, with an olive green exterior decoration with a black stripe at the bottom. The axle running gear was also improved by replacing the original friction boxes with SKF bearing boxes. In 25 second-class carriages of the 5000 series, the original Pennsylvania bogies were replaced by Minden Deutz ones.
Due to the sale of 5000/6000 cars in Cuba, which adopted semi-automatic Alliance clamps to drive through that country, in order to transport them from the Vilanova workshop to the port of Tarragona, four cars were adapted with these clamps, replacing on one side the conventional system of coil tensioners and side bars on the other. These are the cars known as "mansos", but in the end only about thirty vehicles were built, and twelve were shipped to the Caribbean. With what remained, two fixed compositions were formed, equipped with Alliance and destined for special services. Due to this, these mansos continued to be necessary to accompany both compositions. These two cars did not allow passengers and the windows were painted white. Two of these cars are the CC 6029 and CC 6043 that arrived in Móra la Nova in mid-June 2004 from ARMF in Lleida in a very poor condition, due to the high cost of rebuilding both of them, despite the rolling chassis being completely new and this reduced the cost of restoration. Neither the Lleida entity nor the Vilanova Railway Museum had any interest in restoring them because both entities already had other similar vehicles modernized for operating on tourist trains.
In the second half of 2004, APPFI volunteers began the cleaning and protection tasks for these two cars under precarious conditions, because they had to work outdoors, which made the work very difficult, being exposed to the weather and to theft and deterioration of the work being done, and sometimes they were vandalized. It was not until 2012, with the new train shed and adequate facilities, that the rehabilitation could be completed. The work done on these two cars, along with that on the J-400,000 freight car, marked a before and after in what is now the Móra la Nova Railway Museum.
