N scale Lighted track tester for DC and DCC trains - check the condition of your rails

N Scale Workshop I created my own style of a TRACK TESTER for my train sets. When you put it on the track and slowly slide it around on top of the rails it will tell you if you have a good connection in your complete track layout. If you reverse the transformer it will turn the opposite color. If one way is red, the reverse will be green. A very hand tool that you can keep in your pocket to check for shorts, poor connections, and the direction the train will travel on your track.
Note:
The photos show you how I used mine on a layout I designed.
