Reply to "Trolley with reversing bumpers"

I've often thought that a reversing trolley with timed stops is an ideal application for an Arduino-based controller.  Having made this observation, its not anything I've implemented, but the Google machine suggests that others have - in what appears to be varying degrees of complexity.  One of those is having the ability to reduce/increase the voltage with time, so the trolley behavior isn't just sudden stop/start.  You might take a look at this for starters:  https://modelrailroadelectronics.blog/throttles/
