I would appreciate some help to achieve the following: Two vehicles on one loop. First vehicle travels the loop while second vehicle is stopped (off). First vehicle completes loop and stops. Stopping of vehicle one activates vehicle two to traverse the loop while vehicle one remains stopped. Vehicle two completes the loop and stops which activates vehicle one with the cycle continuously repeating. I am familiar with block systems using toggle switches but automating this is beyond my comprehension. Thanks in advance.
