2. Self-braking by hydraulic overrun brake
The FunTrain is equipped with an hydraulic overrun brake. This means that the FunTrain will automatically brake if the Fun2Go slows down. The FunTrain wants to maintain speed because of its mass and presses against the Fun2Go. The slider, which is mounted on the drawbar near the coupling, will slide in and press the hydraulic brake cylinder. The FunTrain will then brake automatically.
