The 8-Way Star Junction is a large junction designed for more than four connections in one space. Whilst more complex than an 8-Way Roundabout, it is designed to take many times more trains simultaneously.

8 Way Star Junction

Pros:

  • Handle a huge number of trains at a time.
  • Traffic jams are unlikely.
  • Much simpler than multiple consecutive 4-way junctions.

Cons:

  • Trains have to slow down to climb slopes.
  • Takes up a huge amount of space.
  • Very complex and costly to build.
  • Trains have to turn right to go left.
  • Trains have to slow down for sharp turns.
  • A stopped or broken down train will be disasterous.
