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.
