Check out our video on sensors! Reed sensors are 100% reliable, small and cheap. We believe that those sensors will replace optical sensors in the near future, because they work better in any aspect, are easy to build and less expensive than infrared sensors.
In the video, we show the design of the sensor and show some train operation with a V200 and the Emerald Express on a small test layout.
