At just 1.0\" × 0.4\" × 0.16\", it fits in cabooses, passenger cars, lightboards, and even N-scale shells where space is tight.\u003c\/p\u003e\n  \u003cp\u003eLooking for more DCC decoders and electronics?

It's not the same as RailCom but serves a similar role.\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eDoes this drive a motor?\u003c\/strong\u003e\u003cbr\u003eNo — the TL1 is a function-only decoder. It controls ONE output (typically a light or accessory). For motor control you need a full mobile decoder like the Digitrax DH126MT, DZ126, or any other mobile decoder.\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eWhat can I wire to the function output?\u003c\/strong\u003e\u003cbr\u003eLEDs (with appropriate resistor), incandescent bulbs, smoke units, sound modules, ditch lights, mars lights, or any DC-powered accessory drawing under 1A continuous. FX3 effects let you simulate prototypical lighting patterns.\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eWill it work with any DCC system?\u003c\/strong\u003e\u003cbr\u003eYes — the TL1 follows NMRA DCC standards and runs on any DCC command station. Transponding readback, however, requires a Digitrax LocoNet system with appropriate detection sections (BDL168, BDL16, etc.).\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Digitrax","offers":[{"title":"Default Title","offer_id":48208789799167,"sku":"TL1","price":15.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0443\/5968\/0161\/files\/image_e751d2a6-3692-4b16-a567-c39b9e00c751.jpg?v=1771768238","url":"https:\/\/squeakystrains.com\/products\/digitrax-tl1-single-dcc-function-decoder-with-integrated-transponding","provider":"Squeaky's Trains \u0026 Things","version":"1.0","type":"link"}
