🚦 Railway Track Circuit: Ballast Leakage, Shunt Sensitivity and Relay Pick-up (3D Blender Line)

3D railway track circuit lab: rails as a leaky transmission line, ballast leakage, wheelset shunts, relay pick-up and drop-away with a signal that fails safe.

⚙ Under the hood

3D Blender-built track circuit with feed and relay boxes, insulated joints and a signal: a live voltage ribbon along the rails shows how ballast leakage and a train shunt change the relay current.
