The Anonymous Widower

The Silent Transport Revolution

Today, I rode in two battery-powered modes of transport.

Returning from Kings Cross, I was a passenger in one of London’s new black cabs; the LEVC TX.

Earlier in the day, I’d ridden in a battery-powered version of the Class 230 train.

Both vehicles are quieter than diesel-powered versions, as is to be expected.

But what surprised me about the Class 230 train today, is that you can have a normal conversation in the train without raising your voice. The D78 trains from which the Class 230 train has been developed, weren’t that quiet.

The Class 379 BEMU, that I rode in three years ago, was also quiet.

I came back from Scotland in a Standard Class Mark 4 Coach, which was also quiet, but it is a trailer without motors and probably plenty of sound-proofing.

Does the design of a battery-electric vehicle with regenerative braking reduce the noise and vibration emitted?

The Class 230 train has an electrical system based on DC batteries and AC traction motors. So there must be aone very clever heavy electronics to manage the power. So there is orobably little in the electrical system to make the clatter one typically hears on a train. The train obviously has a mechanical brake for emergencies and to bring the train to a funal halt, but that was not used in anger on our short trip.
