The MRT Accutrack is a high quality portable speedometer for checking locomotive true scale speed. It is battery powered with an automatic power down when not in use. You just set the tunnel over the track and run your locomotive through the tunnel; the speed will appear on the easy to read LED display. The display will automatically clear for the next locomotive after a short delay.
This unit is a great tool for adjusting locomotives speed for consisted units. No more guessing or running multiple locomotives around the track to set speed CVs. Using the Accutrack, you can calibrate all you locomotive to have similar speed performance.
