This device is designed to measure the scale speed of locomotives or train cars that pass by it.
Two small light sensors mounted discretely under the rails are used to record the speed of anything passing over them and then the device calculates and displays the corresponding scale speed on a 4 digit display.
May be used for all scales.
The Trainspeed 4 includes everything necessary to monitor train speeds at 4 different locations on your layout.
