It seems like my TMCC signal is getting lower at times other times fine.
Lately the engines on various blocks started to runaway when I turned on track power to a block, doesn't happen every time. I ran them this morning for about three hours everything was fine. Went to run them again 2 hours later and started happening again, not the same engines or blocks. Likewise the engines will sometimes stop when under a raise track again not always.
I trying to determine if this could be a wiring problem or could my command base be going bad. Looking for ideas on where to start checking.
Background on my layout, just TMCC (no Legacy or MTH). I have six blocks, three mainlines each controlled by a TPC300 with a 180 power supply, three sidings each controlled by a Power Master with a 135 power supply, various ASC's for switches and accessories and OTC's for operating and uncoupling tracks. Lights and accessories power are from a ZW and KW. I have a 14 gauge copper wire under all the tables for a common TMCC signal and transformer connection. All been running well for the last ten years or more.
