Build your own Track Odometer car with our new Track Odometer assembly. Finally, answer the question of "How many feet of track do you have?". A reed switch triggered by magnets on the wheel of a car counts pulses to indicate feet traveled on the on-board display. Reset it to zero using the reset button, send it around the mainline, and read out the result! A built-in calibration routine allows you to install this tool on any car with any wheel diameter.
