I have been meaning to ask when Lionel added the ENG 99 'all' command to the newer Legacy engines. When I had the D3R guys over last weekend I discovered this feature when trying to line up my TMCC controlled turntable for a guest's MR 261. My Geeps don't respond to it and the only reference I've seen is in some locomotive owner's manuals for that I downloaded from Lionel's site.
