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

Newly-redesigned and coming in at half the size of a KA3, the KA1 will power HO or N scale locomotives with approximately one-third of the capacitance of KA3/KA4 devices (depending on the locomotive and motor).

This Keep-Alive® includes a Blue and a Black w/ White Stripe wire to attach it to a decoder.
