Thank you all for the great feedback. Looks to me that the old post war transformers will do the best job running all of my conventional/PS1 locos.

I believe the board is bad or scrambled or that the transformer(s) are not right. Any feedback on the PS1 problems is appreciated. I do wish I had paid the $40 fee to Trainz to have the PS1 tuneup where they install a BCR and test the boards.
