After changing the power delivery wires from transformers to TIU inputs to 12 ga stranded on four track circuits (TIU inputs), the next time I tried to run trains this happened: With three different locomotives, two diesel (both ERRCo conversions that worked perfectly before) and one steam (Legacy). Both diesels start up fine, respond to horn and bell commands, but when throttle is advanced they move minimally and then “die”, go silent and stop moving. Turn the speed knob back down and wait a few seconds, and sounds return as well as response to commands, but same result with speed knob advanced (“die.”). The Legacy steamer doesn’t even start up, no response to “Engine 25” at all. Re-set its engine number to make sure not “forgotten,” but that wasn’t the problem. This all was with an older Legacy base that to date had been fine. I tried a Legacy 1-L system and then an old TMCC system, and the behavior is the same with all. This is with GRJ’s TMCC signal “buffer” boosting signal maximally, too.
Color me puzzled. What to do, what to test? I have a signal test circuit to use with a VOM, so with advice can look at signal in whatever location needed, I think.
Thanks. Hope all of you remain safe and not needing to expose yourselves unnecessarily to the pandemic virus.
