{"product_id":"lionel-o-1929100-defect-detector-with-sound","title":"Lionel O 1929100 Defect Detector with Sound","description":"Introduced in the 40s, the defect detector came along to take the place of station agents and alert on-board crew of dangerous defects on the train. As a train passes through, the IR beams can detect dragging equipment, gauge temperature, monitor speed and send a signal to the dispatcher and train crew that something is wrong. Now you can add the action to your layout realistically with this all new accessory! The new detector counts your axles and delivers an announcement after the train passes providing an axle count, approximate train speed and the occasional defect! Use the max\/min switch to set a high or low frequency of problems. Every lap around your layout brings a new chance for excitement!\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003e5\" O Gauge FasTrack Section and building\u003cbr\u003eIR sensors detect and count the actual number of axles on a passing train and determines when track is clear\u003cbr\u003eCalculates and relays by audio the number of axles, approx. speed, imaginary milepost information and reports defect detection status\u003cbr\u003eIncludes occasional defect announcements with warning sounds and announcements of imaginary car issues\u003cbr\u003eVolume control and ON\/OFF switch\u003cbr\u003eMin\/Max switch to adjust how often a defect is found\u003cbr\u003eGets power from track - can also be powered from accessory power supply (sold separately)\u003cbr\u003e\u003cbr\u003eProduct Specifications:\u003cbr\u003eGauge: O Gauge\u003cbr\u003eBrand: Lionel Trains\u003cbr\u003ePower: Electric","brand":"Lionel","offers":[{"title":"Default Title","offer_id":42130211143762,"sku":"LIO-1929100","price":94.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0581\/3410\/2098\/files\/1929100-01__94236.jpg?v=1756153095","url":"https:\/\/modeltrainstuff.com\/products\/lionel-o-1929100-defect-detector-with-sound","provider":"Model Train Stuff","version":"1.0","type":"link"}
