First I would like to explain my layout as it pertains to the questions I have.
I have two loops of track one outer loop designated TRACK ONE and an inner loop designated TRACK TWO. Track two is powered by a Lionel 135W power house which is connected through a TPC-3000 a TMCC base. The poin of this was to run both TMMC and non TMCC engines mostly MTH. Track one is a totally separate loop and is powered again by a separate Lionel 135W powerhouse connected to the track though a Lionel TMCC Power Master. This arrangement worked fine even after purchasing a Lionel Legacy steam engine. So I could run the legacy engine on track one or Lionel TMCC and MTH on track two. I have now purchased a Legacy 990 control system that I would like to replace all of the TMCC (maybe)
My questions are:
Lionel says you only need one Legacy Base per layout so in my case this begs the question "what is the definition of a layout" based on my experience so far is my layout is actually two layouts since I cannot control the track power to the track that does not have the ground wire connected to the track. So is my only solution to connect the two loops or is there another solution.
One other question is there and method to turn off the legacy base other than pulling the power cord out. I have all my power supplies connect to a power strip and when I am finished running the I simply shut the power strip off. I tired plugging the base in the same power strip it doesn't power us.
