Three phase motors I think that no other trains have, it can cause problems when its raining I think someone said.
Hello everyone,
Is there anybody in here who knows why does the Class 323 sound like that? What's the secret of it's unique GTO inverter that makes sounds like that?
Would that also be the reason this OBB Taurus (?) loco seems to be practising scales?IIRC (it's the same for Desiro's) then there are certain frequencies that interfere with signalling equipment, therefore these sounds are "notched" out, causing the motors to change pitch frequently.
That's a pretty cool sound!Would that also be the reason this OBB Taurus (?) loco seems to be practising scales?
Who is "someone"? I'd take anything else that someone said may be taken with a pinch of saltThree phase motors I think that no other trains have, it can cause problems when its raining I think someone said.
