Same as in the Tatra T3 (by the way, licensed from PCC of course). But you should see the accelerator moving in a K2 (articulated version of T3, six bogies, two driven, heavier vehicle). The accelerator rotates to one direction and then back again when accelerating (we say it "flips" from position A to position B).
When coasting it behaves normally, places itself to the responding position (either in A or B) and when dynamic braking it moves again two times (not if you coast long enough and allow it to reutrn to positon A). When flipping from position B to A in the electrodynamic brake passes out for a moment and one can feel it. During acceleration there is nothing like this.
t is funny, though. When you are skilled and hit the moment of the "flip" during acceleration with a "lead foot", the car takes again about 600 A, while at some speed. Also, there is the possibility of additional shunting using the addition resistors which are usually active only at the very first moments of acceleration from zero.
Of course, if you do it long enough, you burn them. The K2 has the possibility to keep them connected to maintain "walking speed" for a few seconds. Depends of course on the condition of the wehicle and all its components how it behaves... You have nice videos. Thanks for them.

sorry three boogies, two drive... I was counting the axles first... :-)

Interesting electrics! Looks a bit like the Vambac design used (not very successfully) in Blackpool UK for a time.
