The polarity (or train direction) of the rails is shown on the product. Review: Brilliantly simple idea - This is a brilliantly simple idea - you plonk it on your tracks and it shows you DCC or DC polarity with a single LED. It has save3d me so much time - mainly because my missus can now test the track herself without asking me to do it. It works on lots of gauges and has been great for debugging our N-Gauge layout. Review: Your trains will thank you for this! - This little device is a model railway lifesaver. Its functionalities are to find dead spots faster than a train derails when you least expect it and checks polarity on DC and DCC systems, saving hours of “Why isn’t my train moving?” panic. Compact and easy to use, it keeps your locomotives running smoothly—no more “track tantrums” or rolling stock rebellions. The real benefit? Peace of mind and fewer dramatic re-enactments of Thomas the Tank Engine disasters. Your trains will thank you… or at least stop giving you the silent treatment. ## Features - Warning:Not suitable for children under 14 years.
