原视频标题：[BOMBARDIER IGBT VVVF] BR186 TRAXX F140 MS2e Sound [Inductor Recorded]
--- 以下原视频简介 ---
In this video you can hear the waveforms generated by the Bombardier IGBT-VVVF traction inverters of the BR 186 locomotive, also known as Bombardier TRAXX F140 MS2e. The sounds in this video were captured using an inductor, which captures electrical signals rather than 'regular' sound waves. 

The TRAXX F140 MS2e is a multi-system electric locomotive with a top speed of 160 km/h, capable of running under 1.5 / 3 kV DC and 15 / 25 kV AC. The "F" stands for Freight, the "140" indicates that it uses "Tatzlagerantrieb".
