I am a retired Naval Officer who has built model railroad layouts at my various duty stations then had to tear them down when transferred. Finally settling in SoCal I built a layout in two car bays of my three car garage. While not a real prototype operation, I have tried to give the feel of the BNSF mainline route from Kingman AZ to Flagstaff with some freelanced routes added. I finally made the move to DCC last year, sold off the engines I could not convert and added decoders to the ones I could. Like everyone else I keep asking myself why I didn't shift to DCC earlier as it adds so much to operations.
