In the late 1980s, RENFE decided to sell a significant portion of the obsolete 5000 and 6000 series coaches. A contract was signed with Cuba to refurbish these coaches, but the project was only partially completed. This adaptation involved the refurbishment and reconstruction of the interiors, which were of the compartment type, and the modification of the coupling devices to the American type, in addition to repainting the exterior. Coaches equipped with both bellows and the original headstock configuration, with gangways, were used. Several batches were sent and operated on the island, but after several missed payments, the sale was halted. RENFE was left with refurbished rolling stock with no planned use. In 1992, due to the Seville Expo and the Barcelona Olympics, it was decided to make use of the coaches from the failed Cuban order. Model Electrotren has reproduced several examples of these vehicles over the years, the most recent being the E5097. However, this time we have reproduced for the first time the variant with the original front end of these coaches, equipped with gangways, under the reference HE4029, the B7r-6260.
