153IR Controller Lionels newest offering in the world of layout accessory control is the 153IR Controller™. Using infrared, the 153IR sends a signal across your tracks.

Several can be placed around your layout and wont look out of place like some plastic models on the market today. Powered by a removable track clip or from an auxiliary power supply, the 153IR is a model of flexibility and control. Infrared sensors detect passing trains and activate connected accessories Time delay adjustment knob (from 0 to 5 seconds) Dimensions: 5” x 4 1/2” x 3 1/2” ShipYear: 2001
