At Brenner station, located on the Brenner Pass (), there is a monument to the designer, Karl von Etzel. This station is situated at the border between Italy and Austria and also the operational border between the ÖBB and FS networks. The two companies operate different electrical systems, (15,000 V AC at 16.7 Hz in Austria, and 3,000 V DC in Italy), which requires a stop to change electric locomotives. For this reason, for a long time the operation of express trains from Munich to Verona and Milan was carried out with diesel railcars. Until 30 May 1965 was also needed a second engine change in Bolzano station, as the Bolzano-Brenner section still operated under three-phase AC electrification.
