CrushBugsays...That has to be some sort of electrical motor that is making that sound, wouldn't you think?
oritteroposays...Well it is an electric train... I did mean to put the info into the description, but only put it in the tags.
The train is a Siemens Taurus, ES 64 U2. According to Jimbo's big bag'o'trivia, it has a top speed of 230 km/h, although there is a really similar model which proved itself quite a bit faster at 357 km/h in testing prior to delivery. It also says it has a quill drive, but I'm not really sure what that means or why it would reduce track forces.

greatgooglymooglysays...Maybe a variable frequency drive ramping up speed, combined with wheel slip causing the sound? I've never heard an electric motor make a sound like that.
