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.

Includes Blue and Black/White lead wires to solder to your decoder's keep-alive pads — works with TCS and most other-brand decoders. Input rating 12–16V; works with any scale and any DCC system. More Information Brand Train Control Systems (TCS) Item Number 2000 (KA3) Type Keep-Alive / Stay-Alive Capacitor Pack Connection Blue + Black/White Wire Leads (solder-on) Input Rating 12–16V Scale Any Scale Condition New FAQ What does a Keep-Alive actually do?It stores an electrical charge and feeds it to your decoder when track power drops out, so the locomotive keeps moving and its lights and sound stay on across dirty track, frogs, and gaps. How do I connect the KA3?Solder the Blue wire to your decoder's keep-alive positive (V+) pad and the Black/White wire to the ground pad. It works with TCS decoders and most other brands that offer keep-alive connections — check your decoder's manual for the correct pads. How long will it keep my loco running?Expect roughly 6 to 20 seconds with headlights on for a typical HO locomotive, depending on motor efficiency and current draw.

The Digitrax SHABC is a complete turnout signalling kit for HO scale. A turnout needs three signals to be done properly - a dual-head mast facing the points that can show both routes, and single-head masts covering each leg beyond - and that is exactly what is in the box, along with the mounting board, plugs and hardware. Current-limiting resistors are already fitted. Signalling your layout? Browse our DCC Accessories, DCC Wiring, and the full Digitrax range. What's Included Item Qty Dual Head A Signal 1 Single Head B Signal 1 Single Head C Signal 1 SMP1 signal mast plug 3 Spacers 6 Screws 6 Features Everything for one turnout signal plant - three signals, mast plugs, spacers and screws in one box. Dual-head A signal to show both the straight and diverging routes at the points, plus B and C single heads for each leg. Plug and play 10-pin connectors so signals lift out when you are ballasting or working on scenery. Current-setting resistors built into the board - nothing to calculate, nothing to solder. Pads are provided to attach any signal head to the mast base if you want to mix in other manufacturers. Intended for use with the Digitrax SE8C signal decoder. More Information Brand Digitrax Item Number SHABC Product Type Signal Kit Scale HO Configuration Turnout - A, B and C masts Signal Heads 1 dual head, 2 single head Connector 10-pin plug and play Resistors Built into the mounting board Use With Digitrax SE8C signal decoder Condition New FAQ What is the difference between this and a mainline kit?A turnout needs three signals, not two: a dual-head A mast protecting the points and showing both routes, plus single-head B and C masts for each leg beyond. A mainline kit such as the SH2AB only covers plain double track. Do I need anything else to make the signals work?Yes - a signal decoder to drive the aspects (the SE8C is the intended partner), cabling to reach the masts such as the SDCK kit, and some form of block occupancy detection. Do I need to add resistors?No. Current-setting resistors are already on the mounting board, so there is no resistor maths and no risk of over-driving an LED. Can I mix in signal heads from other makers?Pads are provided on the mast base so you can attach other signal heads if you want a specific prototype. The plug arrangement and resistor board are designed around the Digitrax SE8C.
