Once again, Thanks for the help you've given.
Now all is sorted, I can get on with some modelling. I have decided to put a passing loop in the layout and have a couple of trains running. When 1 is on the way from the town end, the other will leave the other end and pass in the loop.
I have a couple of Grand Daughters who seem interested in the layout, so assuming that when I get the trains running, they will want a go,i am going to split the layout in to 2 parts with each controlled separately. Then there will be no "It's my turn". The split will be the cliff side of the loop.There are 8 points so this will become 4 to each one.
All the best
