Hello,

In order to manage my hidden yard, i am trying to figure out how to detect with contact track of my hidden yard is unoccupied in order to switch the right turnout.
To be more precise, i don't want my trains to park each time they come back toward the hidden yard. I want to be able to launch manually an automatism (Memory) which will open the right turnout to enter the yard. To do this i need to check which track of the hidden yard is unoccupied.
How can i do this ?
How to wire the S88 to check its state...?
Thank you for your help !
