Taboadela gauge changer on the Madrid-Galicia high speed line seen from a Talgo Avril (Renfe S106) AVE service. The T on the signal indicates that the gauge changer is ready for Talgo compositions. If the gauge changer was reafy for a CAF composition, a C would appear instead. August 2024. Photo by A. Rueda #Mail: ad.rueda(at)gmail.com
