Hi I have several MTH diesel locomotives that are PS2, I would like to upgrade them so that I can use the cab one remote. I understand you can use e r r boards to do this but I have not gotten any reply when I asked 3rdrail. I have no idea whether I just need one thing or several things to do this.? I do see on their site there are different types of boards but I don't know which one to use. Any help appreciated thank you.
