What was going on with this 466?

Watch this video.

You'll see that the 1st motor starts for a few seconds then cuts out. The 2nd motor was clearly still working as the train did gain speed but did not have much acceleration on its own. BTW this was an 8-car with a BREL 465 (465031) and a 466 (466023) on the back of it.
Under braking the rheostatic brakes on 465031 would work, so it can't be the rest of the consist that was broken. Even once the train gained speed the motor was still cut-out.

The faulty unit in question is 466022, if anyone has kept tabs on this unit getting fixed/being still broken.

Anyone able to say what was going on.

That's normal - only one car on a 466 is powered, the other is just a driving trailer.

Yeah, 466s are DMOS + DTOSL. T being trailer.
