The Dual Branch-Merge Junction is a high speed, high traffic junction. It branches at the beginning of the junction and merges right at the end, allowing more trains into the junction at once, thus preventing deadlock; it does not use sharp turns in order to maximize speed; it has a maximum of two slopes per path. Trains heading straight, turning right, or turning left all have dedicated tracks, which help alleviate traffic.

This junction works best with Realistic acceleration and if trains can choose between the inner and outer tracks just before entering the junction.

This junction is built for speed at the cost of space.
