After I finished my Ercf v2 build I was immediately annoyed by the Cottentail buffer system, way too difficult to load and way too much drag. I modified the coupler blocks so they run in a straight line and kept other original features like the pre-gate sensors, leds, and the spring part to reduce stress on the filament blocks, I made the Happy-Hare lodge on top with the number of the gate.
