Here's the boring Class 455 that only uses asynchronous modulation. And to top it off, it's a simple 1500Hz carrier. There's no sync - party's over - grab your coat.

This is the same as the Class 321 which also uses the TME 52-35-4 three-phase ACIM and this Vossloh Kiepe traction inverter with 1500Hz CPWM.
