Served USAF during the cold war. Retired Opr. Engineer. Built my first 4X8 layout in HO when I was fourteen using paper route money living on Long Island, N.Y.. Have been in N scale since 1982. The engines then sounded like lawn mowers but soon to come after that was an Atlas RS3 that I think along with Kato changed the whole game. Things have really changed since then. I have switched to Digitrax DCC on my new layout build. Model Railroading never leaves you.
