The Keep-Alive (KA) devices are used to supply power to decoders during times of power interruption due to dirty track or problematic track work.

The Keep-Alive (KA) devices are used to supply power to decoders during times of power interruption due to dirty track or problematic track work.

This decoder has a 21-Pin connector on the front. It is compatible with any TCS motherboard (which include onboard Keep-Aliv technology) which provides easy connections for attaching your speaker, cam, and for the additional lighting functions (F1 and F2).

This device is designed to measure the scale speed of locomotives or train cars that past by it. Two small light sensors mounted discretely under the rails are used to record the speed of anything passing over them and then the device calculates and displays the corresponding scale speed on a 3 digit display.

This motherboard is designed to replace the existing circuit board in a Bachmann Heavy 4-8-2. This board is designed to receive a WOW121 or EU621 decoder and provides an onboard Keep-Alive (KA2 style) for uninterrupted performance over troublesome tracks.

This motherboard is designed to replace the existing circuit board in a Bachmann Baldwin 2-8-2. This board is designed to receive a WOW121 or EU621 decoder and provides an onboard Keep-Alive (KA2 style) for uninterrupted performance over troublesome tracks.

This is the N Scale Drop in decoder for Kato FEF by Train Control Systems.

This motherboard is designed to replace the existing circuit board in a Bachmann Light 4-8-2 (short tender) or the 2-8-0. This board is designed to receive a WOW121 or EU621 decoder and provides an onboard Keep-Alive (KA2 style) for uninterrupted performance over troublesome tracks.
