I am happy there are more people out there building things for their .....ahem..childrens amusment. Mine is a slot car track for my son. Bruce small internet I used the exact same schematic you sent me for the lay out and it is the one that is giving me the problems but Im sure I am being too sticky about the details and tonight I will try it out with the pic with the fence circuit and see how it works (in sure it will be great).
Thanks again for the help I will post if it works or not.
