After the last meeting in the warehouse, I thought of what I can do in the small-scale model team. I looked at the small-scale bogie on Wednesday and I think it might be possible for us to build the actual bogie design in the small-scale. What I think is to add a servo and link it to the switch gears so that it can demonstrate how the switch gear works. Instead of changing the design, I also thought of the possibilities to add the fail-safe design to the small scale model. Like using brakes and ultrasonic sensors to determine the distance between two cabins and control the brake.
