I pulled the plug some time ago, but find that I need to hook up something temporary to test some locos I am re-wiring. I know there are two polarity “standards”; NMRA and LS. I’m looking for which rail is + when loco is traveling forward using the LS polarity standard.
Thought I had this around here somewhere but can’t locate it. I didn’t try Google because I’m likely to get conflicting answers; especially given the two polarity standards for our track.
