LBR Mainlines are arranged in a 3x1 configuration, of:

Left | Bidirectional | Right

Current stage: Development - Building first live test track

Pros:

• Takes up less track than an LL_RR mainline and can be compressed more
• Downgrades to LR more easily where needed
• Allows both over and undertaking

Cons:

• More complex signalling
• Lower capacity than LL_RR
• Junction positions are restricted

Minimum width: 5 tiles: Primarily (L__B__R), Connectors (L_L_R_R)
