In a Transmogrified Junction the entrances from north and south are connected in a central square with the exits to east and west, and vice versa for an outer square. There is a 3-way version called a Half Transmogrified junction.

Aligned transmogrified junction with bridges and path-based signaling

  • Maximum signal distance: 6
  • Minimum tiles between double bend: 5 (diagonal)
  • Area: 12 x 12 (50 extra square tiles)

Variations

Large transmogrified junction

With a larger central square 7 wagons may fit between the turns on the slow path.

Compact transmogrified junction

In this compact configuration the junction is very slow.

Transmogrified junction

Unaligned but slightly smaller junction. Tunnels instead of bridges and no path based signaling.
