The Dual Transmogrified Junction is a variation of Transmogrified junction for double mainlines. This junction doubles the number of "junction squares" (the distinguishing feature of Transmogrified junction) to 4 and makes use of both bridges and tunnels to make it more compact.

Another version of Dual Transmogrified junction is combination of Transmogrified and dual version of Half Transmogrified junctions.
