While the new underground station of Montmeló was being constructed, the line was rerouted onto the platform of the Barcelona - French Border High-Speed Line. The connection between this line and the original was a double curve shaped like an "S", with a rather impressive change in gradient.
In the photo, we see the Catalan Talgo No. 00073 from Barcelona Termino to Montpellier winding along this curious curve.
Shortly thereafter, the Estrella Costa Brava No. 00370 from Madrid Chamartín to Cerbère appeared.
