Frustrated by intermittent locomotive performance whenever you run trains? Spending hours troubleshooting tricky frogs and subpar electrical pickups? You don't have to pull your hair out anymore! Power problems are a thing of the past for Keep Alive® users.

Though not the first company to attempt the idea, TCS was the first to bring an uninterruptible power supply to the North American DCC market that was both powerful and affordable in the form of the "Keep Alive®" device. Ever since its unveiling in late 2012, "Keep Alive®" has become a household name. Often imitated, but never equaled!

Keep Alive® technology eliminates issues which arise from poor track conditions and/or poor electrical pickups. For sound decoders specifically, Keep Alive® prevents sound interruptions and engine stalling that can occur from hiccups in power delivery.  When power to your locomotive is interrupted, Keep Alive® delivers up to several seconds of additional power to keep your locomotive running through dead spots on the track. When used with a TCS decoder, all of the functions will continues to run - motor, lights, and sounds. Cutting power to your layout will also activate the Keep Alive® device, so don't be surprised if you still hear the locomotive making sounds for several seconds even after shutting down your layout. Nothing's wrong - that's Keep Alive® doing its job!

You can now find Keep Alive® devices included in Factory-direct Models, including the latest SC-44 "Charger", ACS-64, and K4 releases from Bachmann! Don't miss your chance to own these fantastic models filled with awesome TCS features like WOWSound, Audio Assist® and Keep Alive® right out of the box! Keep your eyes open for more models with WOWSound and Keep Alive®, coming soon!


Question: How do I connect a Keep Alive® device to my TCS decoder?

NOTE: ALL TCS decoders are compatible with Keep Alive®! Yes that includes N and Z scale and Fleet Lighter decoders! All TCS decoders are also defaulted to support Keep Alive® without any programming. Just plug and play! This is not true for all manufacturers and decoders! If you are unsure if your decoder supports Keep Alive® you should contact your decoder manufacturer.

Keep Alive® supporting code for TCS decoders was implemented fully by November 2012. If the date code in your decoder is before this date, Keep Alive® may never enable. Other decoder manufacturers have since followed with their own support for the device. You may need to consult your decoder manufacturer regarding their own support for Keep Alive® on specific devices. CV's 250, 251, and 252 read as the month, day, and year of manufacturing in a TCS decoder.

NOTE: Diagrams for attaching Keep Alive® to many TCS decoders can be found on our website by visiting the product page for said decoder and clicking "DOCUMENTS."

TCS Does not officially condone the direct attachment of Keep Alive® devices to certain products, such as the M-series decoders. Removal of the shrink wrap and other hand work WILL VOID your 1-year manufacturer's warranty. TCS instead offers variants of ALL of our decoders to include KA wires from the factory, making your job as simple and splicing two wires, removing the stress of dangerously working on the decoder itself.  ANY decoder (excluding decoders with Keep Alive® on-board) can be ordered directly from TCS with the "-KA" variant tag for attaching Keep Alive®, but may or may not have an official SKU. Contact TCS sales for more details on "-KA" variant decoders, or navigate to the product page for any decoder and click "VARIANTS" to view all variants of that particular decoder, including Keep Alive® ready "-KA" variants.


Question: How do I connect a Keep Alive® device to a decoder NOT made by TCS? Is that possible?

Remember that other manufacturers have followed TCS with their own support for Keep Alive® and similar devices from other manufacturers. Not every manufacturer, and not every decoder supports Keep Alive®! You need to consult your decoder manufacturer regarding their own support for Keep Alive® on specific devices should the need arise. TCS cannot advise on hardware or software support of Keep Alive® in other manufacturers' decoders. If you would like to attach a Keep Alive® unit to a non-TCS decoder, you need to connect the wires across the output of the bridge rectifier on the decoder. You will need to consult your decoder manufacturer for a schematic or wiring diagram if you are not able to locate these two points on your decoder:

  • +12Volt DC Common (Blue wire on KA devices and most DCC decoders)
  • Decoder Ground (Black & White wire on KA devices. May or may not be marked on a decoder as "GND" or using The "Ground" Symbol)

If you are able to find these two points on the decoder, solder the two Keep Alive® wires and you are finished. If you are not able to locate or identify both of these connection points, your decoder manufacturer may be able to provide guidance or a schematic.

Keep Alive® is a DC voltage device. Do not connect the wires from your Keep Alive® device to track power! Attaching the unit to track power will do nothing if not destroy the unit.


Question: What is the difference between all of the different Keep Alive® products TCS offers?

All Keep Alive® devices operate in the same way and are equally compatible with any decoder. KA1 and KA2 devices have equal capacities to each other, and are approximately 1/3 the capacity of the KA3 and KA4 devices while at the same time being roughly half the size of their counterparts. Physical dimensions are the only considerable differences between Keep Alive® devices. These dimensions must be taken into account prior to installation, as choosing the wrong device may interfere with the installation.
