Thank you for all the replies and advice. I am now trying to absorb as much information into my aged brain so that I can come to a decision D

Many thanks to all who replied. I shall look at the suggestions and see which might be my better options as I know almost nothing about programming languages or protocols. I had a picture in my mind that I would only need one programming circuit with which I could set up the servos but this looks as though my imagination ran away with me. Can anyone point me to a site where I can read, in very basic terms, how thoekse units work..currently I am using servos with micro switches to limit travel and to change frog polaritybut I want to switch to something a little less Heath-Robinsonish and more reliable. Many thanks for your time and interst

Can anyone suggest a simple circuit for a basic servo controller for one or two turnouts
