I've almost retired and am looking to devote a lot of time to my life long dream. I'm going to build a railroad. I know I want it to be DCC and to that end have purchased the Prodigy Advance 2. I have also signed up for the 20th Century limited and will be looking to detail the interiors. I am interested in building the Central Midland (Atlas layouts) as shown on Atlas' website and in an old layout book I have.
