The Braided Junction is optimized for compactness.

Braided junction

Pros

  • Very compact
  • No deadlocks since tracks split before they merge.
  • No loops.

Cons

  • The slopes and the sharp turns make trains go slower.
  • Signal distance is 7 tiles on straight track over the bridge.

Variants

Adding signals north and south of bridge instead of using path-based signaling will make the crossing get a 5 tile signal distance on the straight track. The crossing will be slightly less compact.

This is a compact variant for a sideline junction. Quite slow though:

And here is a compact variant for a mainline junction. Also quite slow:

Braided mainline junction

This version is faster with straighter track. Better overall throughput with shorter tunnels and bridges:
