The same method of regulation is used on CD 162 (Pershing) and CD 362 (Ace) locomotives, although the sound sequences are different. There are 3 frequencies used in thyristoric regulation 1st: 33 Hz, 2nd: 100 Hz and 3rd: 300 HzRotterdamMetroLover wrote: ↑27 Nov 2018, 21:49 Even though this train is nice, I still love the ICM trains. The chopper startup especially. (For those of you who don't know the chopper startup, basically the same startup as the T6A5, only a little higer pitched.)
The sound sequence of CD 162 (362) is like this: 33 Hz -> 100 Hz -> 300 Hz
The sound sequence of Tatra T6A5 is like this: 100 Hz -> 300 Hz (Tatra T6A5 uses 33 Hz rarely, for example when, creeping forward in a traffic jam)
Here are some sound samples:
CD 362 (Ace)
