Hi Tony, ? The cost element of the extra hardware hadn't slipped my notice and I am having to build my system with cost restrictions just to prove to my wife this isn't a whim, so using Sprog and Arduino with both current sensing and optical sensors,? I was partially driven to re-think the turnouts and blocks issue when I tried adding signal masts as jmri wants to add them to boundaries to blocks? which works fine when the turnout is a separate block, when I tried SSL Dispatcher need sections to have directional sensors? so that bamboozled me .
Thanks Steve
