NCE 524-149 No Halt Medium – DCC Keep-Alive Module

The NCE 524-149 No Halt Medium is a DCC keep-alive module that stores enough energy to carry your locomotive through dirty track sections, dead frogs, and brief power gaps — eliminating stalls, sound dropouts, and light flicker caused by imperfect electrical contact. Sized for medium HO locomotives, it wires into the decoder's keep-alive input and works silently in the background: when track power blinks, the module takes over and the locomotive keeps moving. A must-have upgrade for reliable operation on complex or older layouts.

Arizona Hobbies is an authorized NCE dealer in Tucson, AZ, and stocks the full range of NCE keep-alive modules.
