Adding a Wye to your layout can be difficult because it consumes a lot of table space. Adding a Double Wye like I did accounts for why my Lionel layout is so large however it allows trains to reverse in both directions without ever having to lift a car from the track. I'm sorry if the video is long. Maybe it will help gives ideas for your layout. In any event, a Double Wye also acts as a Figure Eight. Enjoy!
