--- 以下为原视频简介 ---
It's SIBAS 32 again! It's running that wicked PCFM sound as well that we know. The current collect of the train is placed on the same bogies as the ones which drive, only loosely adhering to the discontinuous 750VDC third rail. You can see in the video how the traction inverter gains and loses power frequently as the truck travels with poor power rail contact. On 750VDC, unlike the Class 350/360/380 on 25kVAC, the Siemens Desiro Class 444/450 uses:

575-675Hz PCFM, 1450Hz PCFM, 3P

Noise gate post-processing:
Background noise sample
48dB noise reduction

Equipment used:
2x 1000mH telephone pickup coil to single pole TRS 3.5mm
Tascam DR40X
