«Catalan-Talgo» (Renfe Talgo III RD) in 1991, being pushed through the gauge changing facility in Port Bou. As this train has no door blocking, it is possible to watch the gauge changing process from an open door. The broken sign "Limite de Renfe" on the right warns the driver that it's not a good idea to proceed with a wide gauge locomotive. After a brief stop, a SNCF locomotive pulls the train out on the other side.
