The 4-Way Triple Axial Junction is an expensive but very fast junction for special direction-crossing.

Triple Axial Junction (simple)

12 simultaneous trains

Junction Criteria

Cost	Expensive
Construction Difficulty	Hard
Tunnels	Yes
Bridges	No
Breakdowns

Sharpest Turn	1
Hills	No
Split Before Merge	No
Direct Paths	Yes
Natural Turns	Yes
Deadlock	No
Loops	No
Signal type	Basic

Handles a very large number of trains at a time.
Uses special directions -> "Top vs Bottom" and "Left vs Right"
Small Area needed (12x12)
Few sharp corners (see improved version for high speed)
No Hills are needed (for extreme high speed)
No Deadlocks or Jamming possible
No Merging or Splitting of the lines
Handling of single-lines and dual-lines possible. That's the reason no Splits or Merges are used. Do it by your own wishes.
Each line starts one level higher when entering the junction than when leaving.
