In the early-80s, RENFE hired some Corail cars (A10rtu and B10tu) from SNCF, and used them on various flagship services, while Class 9000 and 10000 cars were being ordered. These Corail cars were mounted on CAF-GC3 broad-gauge bogies, very close to standard-gauge Y32 bogies used in France. These were later used under Class 10000 and Bc10x-9600 cars, together with Bc10ux couchettes cars of SNCF diagrammed on French-Iberic sleepers from 1985 to 1996.
In those days, Corail services of RENFE ranked as good as "Electrotrenes" (fitted with Class 432 EMUs) and were subject to Supplemento B.
One can notice the vinyls with RENFE logo and brand, stuck on those of SNCF.
