  1. Z-4000 Track Power to TIU and Signal Strength from TIU -- Isolated problems

    Technical Model Train Forum
    Large MTH DCS layout idle for 12 years of wife's terminal health problems has a few dead signal spots (power is good). Some improve with cleaning and I plan to try some light bulbs or filters soon. I use 3 Z-4000 with 3 TIUs and need to check my logic. All TIU outputs used as fixed and set at...

  6. Confused over MTH DCS Options

    O Scale
    From what I can tell MTH has used the product code 50-1001 for the DCS Remote Control Set since they first started producing it in 2000. I'm in the market to upgrade from conventional control to DCS as I have a lot of MTH trains. I've found a few older sets for a lot cheaper than the $350 new on...
  7. Beginner transformer/power and wiring questions

    Beginner Q & A
    Ok, let me first start off by saying that the layout I am constructing will be 100% protosound 2/3 and dcs. My only previous experience has been with a single loop conventional ac layout. On this new layout I will only be running two trains at the same time with around 5 lighted cars on each...
  8. Mth dcs remote question

    DCC Forum (Digital Command Control)
    For some reason a (P) shows up next to my engines on the display. (L) has shown up before which stands for LASHUP and I did do a lashup and it should be there, but I can't find anything to explain the (P). Does anyone know what that means and how to get rid of it? Thanx.

    DCC Forum (Digital Command Control)
