Looking for some assistance choosing a DCC system. I will begin building my first semi-perm layout next month in the basement of my house. It will be HO scale and will occupy the walls of a 10x16 room. Basically it's a modified Ian Rice design with a scenic side and a staging side. I would like to someday have a fully computer interfaced DCC system that is capable of running fully automated "operating" sessions. My goal is to be able to just let the trains run when guests are over or when I just feel like watching. Other times I would like to be able to run in semi-auto mode where the system runs scheduled trains as I operate a local switch job. Of course, full manual mode for times when several people want to operate together is required as well. I would like to have realistic signaling tied into the system somehow...Can this control trains and provide safety at crossings and switches and such? I really like the features that Digitrax offers, but I also really like the simplicity of the NCE Pro Cab. I want to run my trains not become a PHD in DCC if possible. I've been a model railroader most of my life. I've done DC N and HO and most recently O Gauge 3 rail with Lionel TMCC. DCC is somewhat new to me. I've read a lot about it and feel that I understand the basics, but I would like advise from those of you that are more experienced with what I would like to accomplish. Thanks.
