I just ran my LC+ New Haven FA AAs using the App for the first time. I can't believe how easy and fun it is running the trains with the smartphone. The Video also explains how to make the various adjustments to the sounds, momentum, speed limit, etc.
I know that such features have been around for a long time, but I avoided them because I didn't want to make running trains too complicated. IMO, what makes the LC+ technology so brilliant is that it's so easy to use. This App can be used by model railroaders from age of 4 to 110. All one needs to do is watch the How To Video posted above by Dave Olson, and then run your LC+ locomotive! Arnold
