Two things. The entire NMRA standard NEVER mentions AC in any of the specs, I have read through them. It does talk about RS422 communication, and the signal. If, as you say, you've been in the industry then you should understand that a square wave digital signal is NOT AC. Yes, it looks somewhat like AC, but it is not, it is explained in the link I provided. Second, the Wiki I linked is referencing the NMRA standard, and much of it is taken directly from the NMRA standard as well. Again, a square wave digital signal is not AC. Here's the definition of AC Power: "Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time " The DCC signal does not meet that definition, it is technically not AC. I too worked for the Gov't as a Computer Scientist, and Engineering Project Lead, with a degree in Computer Engineering Technology for over 31 years. I did say in my first post that DCC had an AC component, I was just trying to convey that it was "AC-like", because most people really don't understand digital communication very well. However, it is NOT AC.
Again, my point in bringing this up was because someone asked about running LionChief engines on the track running DCC. Regardless of what type of power is supplied with DCC, it works fine with LionChief engines.
