Thank you. Shuttle appears to be the magic word. Did say I have but a small brain

I am but a bear with a small brain. I wish to create a ping pong single line running separately to my main tracks around the garage. Wish this to be automated as I don't want to keep reversing the direction manually. I run dcc and as soon as I looked online found loads of reversing loops, but no obvious solution for back and forth. Any steer to something that may help would be appreciated
