Hello guyeh • Was the Surge Protector the final answer to this issue?
I leave the power to all four main lines on all the time, 100% power. One Lionel Brick to each main line. I turn on the Hand Held DCS first than the 100% Power.
Check all the connections to the TIU, & install new batteries in the DCS.
Hope this helps. I also use a Surge Protector for the bricks & all the electronics.
Great discussion topic.
