German train "sings" while departing station

The Siemens Taurus is one of the best German locomotives in production today, but it doesn't just have high speeds and a efficient performance, it also sings! Listen along as the train hums the major scale as it starts taking off. How cool is that?
The Siemens taurus OBB 1060 is part of the EuroSprinter family of electric locomotives by Siemens Transportation Systems. The first Taurus OBB was presented in 1999 and since then has been used in both heavy freight and long-distance transport.
