Now you can experience hiccup-free sound and operation with any DCC decoder and the new CurrentKeeper.

The CurrentKeeper provides continuous sound and smooth operation by maintaining uninterrupted electrical power for up to 10 seconds - perfect for dirty track and finicky runners.


The CurrentKeeper includes a 2-pin plug on the end of the wiring harness, which we anticipate will work with newer products with a matching plug (like the SoundCar).

Basic soldering skills are required to for installation on the TSU-1000, TSU-750, and AT-1000 decoders.

ADVANCED SOLDERING SKILL is required to install with BW-1000, GN-1000, IM-1000, and KT-1000 decoders.
