I’m currently just gathering cars and track and have most of what I want. I travel to Japan a few times a year for work and get things while I’m there. I’m at a crossroads on whether to stay DC or run DCC I’ll add my as of now track plan. All my engines are DCC ready but the cost of adding decoders to every passenger car seems costly. If I only add decoders to the engines will it mess the existing passenger lights with no decoder? Layout is 8x4. Correct me if I’m wrong but I can use 1 Kato 29-125 controller D103 for this layout? Next Japan trip is in 14 days.
