Thanks everyone for your comments. Illuminating and indeed helpful. Mercat and ModelerXYZ encapsulate my take on the latest tech. As a result I have built a small layout operating both DC and DCC with a number DCC Concepts signal box levers (excellent). This is going to be my MO for the near future. Some of the developments envisaged and described by 96RAF are exciting but a long way down the line (forgive the pun) I suspect. "This Is The Way"
