I am sure this is a thing that i did with my gdad long ago..
I seem to remember a "train onboard" DC layout jigger requiring 2 capacitors(a bi directonalsystem), with something like 2 diodes (in set directions) to protect them, that made the train power up and slow down naturally when the power was cut to a section of line (or over unpowered points or dirty sections). It added a kind of realistic spongey feeling to the controller where you set the speed and the train woud respond and when you wrench it to zero you get a sense of "braking slowly". If i run my HSTs over dead track it just goes from like scale speed of 320kmh to 0 almost immediately which of course would likely kill or best case injure everyone onboard.
Can anyone help me with this? I am not the engineer he was but would like to recreate. Not that i will be hacking apart any of my brand new trains to try it, but might be a fun experiment on one of my pocket line trains as a POC. Or is it already a familiar thing for DC? Not had much luck with googling it, it seems many just say capacitors are just used to eliminate EMF on DCC. But i beg to differ.. there was no DCC back then and i know nothing about that.
