- An Alsthom networker with regenerative braking. At the time of filming only this one alsthom networker did this.
Also at the time of filming it was common for brush networkers to have regenerative braking (so I didn't film it), but not long afterwards all of the brush networkers had the regenerative braking turned off. and now all of the brush motors have been replaced. (So I have never filmed the sound of a brush networker regenerative braking)

None of the motors from any of the networks were replaced, just the BREL/ABB units had their GTO traction inverters replaced with IGBT equipment.
@Leetrainz I work with the units so my guess is 465920? Strictly speaking these units are using rheostatic brake rather than regen brake (braking using resistors rather than back into the 750v). Regen on GEC units is disabled (always has been, and was on Brush units) along with rheo mostly although unlikely it will be reinstated. All Hitachi units, along with 376s have both regen and rheo operative.
Regenerative braking on electric trains is the best equipment that is used to bring back electricity to the National Grid.
I am not entirely sure how many trains are putting their motor braking back into the third rail or overhead wire. It makes a lot of power surges and a lot of equipment can't handle it. A lot of trains in the world waste their regenerative braking electricity in their resistors, as the main purpose of it is only to save the cost of replacing the brake pads. Although I do not know which particular trains do this.
@@benolifts Take it that trains have had problems and have broken down many times.
Why did they disable the regenerative motors?
I miss Network Southeast, and South Eastern Trains, not Connex, Connex was a failed company
It was very unreliable.
465919 is currently the only one that has it
Really? I thought none of them have it
@@benolifts every now and again Southeastern turn on the regenerative braking on some Networkers. Not long ago 465912 also had it, and now it's turned off. I wonder why they do this
I managed to get on 465919 the other day, only one of the driving coaches has it, and only sometimes it works properly, sometimes the regenerative braking cuts out at around 25-30mph. It kept doing it between Orpington and Lewisham, between Lewisham and Charing Cross, it was working properly. I stayed on it until Grove Park, it was working properly until that station. I don't know why it cuts out like that. When you went on this 465/2, did the regen sometimes cut out at around the same speed?
