Sounds of a Class 745 FLIRT (Clear IGBT pulsing)

The famous Stadler FLIRT has an interesting sound to it, with the traction motors being driven asynchronously up until around 40mph where the traction converter switches to synchronous control, very similarly to the Alstom Aventra and Electrostar trains. This is my cleanest take yet on the Class 745, with little to no background passenger noise, listen with headphones for the best effect :) Recorded on 12/09/2024 onboard 745102. Tascam X6 32-bit in A-B configuration + contact microphone in a 1-2 configuration mixdown.
