The discussion centers on creating a speed limiter for a 262 Lionel Line O gauge train, utilizing a modern SCR/TRIAC controller that operates on a 20V peak AC wave. The user experiences challenges with speed control, as the train frequently stalls when power is reduced. The proposed solution involves implementing an optical detector to monitor wheel revolutions, paired with two 555 timers to regulate power based on detected speed intervals. This approach aims to limit the train's top speed while maintaining the ability to revert to its original configuration.
