You may have heard it? When a Siemens ES64U2 type locomotive enters or leaves that station, it makes music, it produces a melody. Some say it sounds like an Alt-Sax. Listen to it:
The ÖBB has recorded the sound for you, from one of its 1016/1116 series locomotives, and you can download it here.
The sounds are being produced by the traction convertors (German: “Stromrichter”) of the locomotives. The current from the overhead wiring enters the locomotive and needs to be ‘converted’ before it can be used for the 3-phase current motors of the machine.
Which locomotives make this sound? Well all the machines with 1 cabin door 😉
