Led by Transap's D-2304, the "Expreso del Recuerdo" heritage train stops on the main line of Til Til station waiting for the authorization to move on. Just behind the convoy it is possible to see the "Altos de Chicauma" hill, which marks the division between the Metropolitan and Valparaiso regions. From this point onwards, until Summit station, the train must fight against the steep slopes that characterize this route, which forced its electrification in the early 1920s.
