    The Train Control Systems KA3 Keep-Alive® is a compact stay-alive capacitor pack that feeds backup power to your DCC decoder whenever the wheels lose contact with the rails. No more stalling on dirty track, dead frogs, or insulated turnouts — the KA3 keeps a locomotive running with its lights and sound on for roughly 6 to 20 seconds during a power interruption (depending on the locomotive and motor). It includes Blue and Black-with-White-stripe lead wires to solder to your decoder's keep-alive pads (V+ and ground), so it works with TCS and most other-brand decoders that accept an external keep-alive. Browse more decoder add-ons in our DCC Accessories collection, shop the full Train Control Systems lineup, or pair it with a new sound decoder from our DCC Decoders collection. Features Keep-Alive® stay-alive capacitor pack eliminates stalling on dirty track, dead frogs, and insulated rail joints.

The KA5-P has a simpler 2-pin plug for decoders with a standard Keep-Alive socket. How long does it keep the loco running?Roughly 6–20 seconds depending on the locomotive's motor efficiency and what lighting/sound functions are active. Do I need to solder anything?No. The harness is pre-wired with the connectors needed for a WOW101 installation.
