With the layout progressing quite well, old time logging theme, I am now at the point of seriously considering going to DCC in purchasing a digitrax system. On the layout I have several hand made turnouts that work good and have had no problems on a DC system. My question is: can they be used on a DCC system or will I have to alter them some way (and how). They are #4 & 6's with power routed frogs. Thanks in advance for your input..Ron..
