evidence: Lastly since you mentioned Vande Bharat, the same company Medha servomotors that designed the power train for T18, also designed a new feature for WAG7. WAG7 did not have regenerative braking losing all the energy while braking through roof mounted rheostats and heat. Medha designed regenerative braking for them and also met the design requirement of IR that regenerative braking should be active down to 10kmph. This loco was trialled in Jhansi division and was successful. No word on mass production. This is a freight loco. [...] This is very interesting, I didn't know of this. I thought it was very difficult to do regen braking on a DC loco, and that's why most/no railway systems did so?vsunder wrote:Lastly since you mentioned Vande Bharat, the same company Medha servomotors that designed the power train for T18, also designed a new feature for WAG7.
