Model Railway Experiments

A collection of experiments including a simulation framework, NMRA DCC protocol port to ESP32, and control logic for model railways - turning a miniature physical world into a real-time, synchronized digital system. Model railways are a perfect microcosm of larger systems: timing is everything, physical movement can't be buffered easily, and reality (track conditions, mechanical delays, signal interference) pushes back constantly. These experiments sharpened my intuition for irreversible, real-time flows.
