U-Turn Rail
R-10
A loop at the end of double track that turns the train straight back.
A slightly unusual part that closes off double track without creating a dead end. It sweeps around widely inside, so it takes more room than it looks.

Build with these exact dimensions
You can lay out every part, U-Turn Rail included, using real-world dimensions. It accounts for the free play in every joint, so you know whether the loop closes before you build.
