## Overview

The RKtt1 Track Tester Module is a compact, battery-free device designed for model railway enthusiasts to quickly and accurately test DC and DCC power on N, OO, and HO gauge tracks. Featuring a tri-color LED system, it instantly indicates track power type and polarity, helping users locate faults and dead spots with ease. Manufactured in the UK, this tool is essential for maintaining smooth, uninterrupted model train operation.

## Description

This track tester works on OO, HO and N Gauge track and enables you to quickly test track for DCC or DC power as well as also helping you to locate faults at track joints, points etc. To use, simply place it across your track and the multi-coloured LED will either display Orange for DCC power, or Red and Green for DC power with the colour indicating the positive or negative. The polarity (or train direction) of the rails is shown on the product.

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.
Review: usefull little thing - so easy. Run along the rails and if you get a flicker you run over the point more slowly to find the problem. Nice little gadget. Edit April 30th this just saved me ages of trial and error to discover a bad fishplate on my track. If I could give 6 stars I would such a great cheap thing for the tool box don’t hesitate buy one !
