trainman 2001, pig tails are okay where you run into a problem if more than one power drop is in same block that is where DCS has issues. I have them on my layout and haven't had any issues once i delegated one TIU channel to one Lionel BPC and one transformer per TIU channel I have perfect 10's and nary a error message unless this old senior forgets to turn the transformers on!!
thanks for the update and I Wish You And Yours A Safe And A Very Merry Christmas.
