In the mid-eighties, a group of 10000-series passenger cars in various versions arrived at RENFE. Intended for nighttime services under the name "Estrella," they offered speed capabilities to travel at 160 km/h, GC-3A bogies, soundproofing, comfort, air conditioning, and a level of interior design previously unknown. Built by CAF, MACOSA, and BWE, they formed different sub-series: AA 10001-10037, BB 10201-10296, BBL 10601-10620, BBL 9601-9660, and BBR 10801-10821. Shortly before, this same operation had taken place for daytime services with similarly innovative vehicles, the 9000 series and some baggage cars. All this rolling stock introduced a splash of color, due to its livery, that was hitherto unknown, and it served to gradually phase out equipment from earlier eras. The precedents were the Corail coaches rented from the SNCF at the beginning of that decade on the occasion of the World Cup held in our country, which is why ours bear a resemblance to them.
In the case of the BR4x-10.815 railcar, its initial registration was BBR-10815, a mixed second-class and bar-cafeteria railcar. Built in 1985 by MACOSA at its Poble Nou factory in Barcelona.
Starting in the years 1996-1997, a decline in the long-distance service began as they were replaced by Talgo trains, but on certain routes they continued to offer service, as would be the case for the two cross-country services that ran from Barcelona to Andalusia and the other to Galicia, which were also the longest routes operated by RENFE. Other coaches were transformed to become part of the new Arco daytime service that ran along the Mediterranean corridor at 200 km/h. At the beginning of the 2000s, Talgos and the creation of high-speed lines progressively pushed conventional rolling stock aside until replacing it completely. In July 2009, around forty of the coaches that operated the cross-country lines were set aside to be scrapped in Móra la Nova, with half a dozen vehicles remaining, heavily damaged and also awaiting their end, but in February 2024 the Town Council of Mont-roig del Camp purchased one to be transformed into a restaurant and placed on the municipality's beach. The project and transformation were carried out by the workshop of the Railway Museum of Móra la Nova.
