gavino200 Posted December 22, 2020 Share Posted December 22, 2020 I kind of like it. Fresh and unexpected. 1 Link to post

marknewton Posted December 24, 2020 Share Posted December 24, 2020 Regenerative brake differs from dynamic brake in that the energy created is fed back into the overhead wire. I don't know the specifics of the traction package on these trains so they may not have this problem, but on some of our trains with VVVF traction control the regen can drop out during heavy braking.  Cheers,  Mark. 1 Link to post
katoftw Posted December 24, 2020 Share Posted December 24, 2020 Do they drop out on first heavy braking application? Or after multiple heavy braking application? Link to post
