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: Great kit - Great piece of kit, highly recommend ## Features - This handy little module has been designed to test track for DCC or DC power - Uses a dual colour LED and a handy PCB pillar for easier, less fiddly handling - When DC is detected the LED will be either green or red, when DCC (16VAC) is detected both LEDs light and the colour will be orange - Ideal for testing DC/DCC model railway tracks for power continuit - Designed and manufactured in the UK by Rk Education ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07XQBNGHH | | Assembly Required | No | | Batteries Included? | No | | Batteries Required? | No | | Customer Reviews | 4.6 4.6 out of 5 stars (210) | | Date First Available | 8 August 2021 | | Item model number | RKtt1 built | | Manufacturer recommended age | 14 years and up | | Package Dimensions | 6.2 x 3.2 x 1.5 cm; 20 g | | Scale | HO | ## Images ![RKtt1 N-Gauge, OO/HO Gauge Track Tester Module for Model Railway DC/DCC - Constructed - Image 1](https://m.media-amazon.com/images/I/71xokRa-WbL.jpg) ![RKtt1 N-Gauge, OO/HO Gauge Track Tester Module for Model Railway DC/DCC - Constructed - Image 2](https://m.media-amazon.com/images/I/71xLy2ggG5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliantly simple idea *by D***H on 19 May 2026* This is a brilliantly simple idea - you plonk it on your tracks and it shows you DCC or DC polarity with a single LED.

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. ## Frequently Bought Together - Rk Education RKtt1 N-Gauge, OO/HO Gauge Track Tester Module for Model Railway DC/DCC - Constructed - Peco PL-41 Rail Cleaner Track Rubber - Hornby R910 OO Gauge Fishplates (Pack of 12) - Model Railway Accessories, Spare Parts and Train Accessories for Hornby 00 Gauge Model Railway Sets - Scale 1:76 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/453417591-rktt1-n-gauge-oo-ho-gauge-track-tester-module-model](https://www.desertcart.tn/products/453417591-rktt1-n-gauge-oo-ho-gauge-track-tester-module-model) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-02*
