I'm getting a DCC System ( my Prodgy Express is in the mail) but I have some locomotives that Are going to be difficult to convert over to DCC, like my GE 44 ton switcher. Its an important part of operations. Now my question is, can i run this one locomotive off dcc? I have my layout block wired already. Couldn't I technicaly hook up the DCC to Cab A on my selector, and have a regular DC power pack control my 44 tonner?
