Model Railway Buffer Stop remix

thingiverse

I intended to integrate this with my HO scale train. I configured end stops on both sides of the track and, thanks to an Arduino Uno board, it can detect when the end stops are contacted and direct the train in the opposite direction so it simply goes back and forth on a straight track. I did not want it to simply collide with the bumper, slamming it each time....so I fine-tuned it a bit so I could attach springs to it so it would have some flexibility when hitting the end stop.
