原视频标题：[BBC GTO VVVF] SBB Re 450 Sound [Inductor Recorded]
--- 以下原视频简介 ---
In this video you can hear the waveforms generated by the BBC double-pulse GTO traction converters of the SBB Re 450 locomotive. The sounds in this video were captured using an inductor, which captures electrical signals rather than 'regular' sound waves. 

The SBB Re 450 is an electric locomotive with a top speed of 130 km/h that operates under 15 kV AC. It is operated by the Swiss national railway operator (SBB) in S-Bahn services around Zürich.
