The Quad Branch-Merge Junction is the direct evolution of the [[Branch-Merge Junction]] and [[Dual Branch-Merge Junction]]; allowing four entrances and four exits, in essence doubling the appropriation power of a Dual Branch-Merge Junction.  Although still in its infancy, the quad branch-merge junction is able to handle quite a load of [[Mammoth trains|large trains]] (20 cars) with very few backups.

The Quad Branch-Merge Junction is the direct evolution of the Branch-Merge Junction and Dual Branch-Merge Junction; allowing four entrances and four exits, in essence doubling the appropriation power of a Dual Branch-Merge Junction. Although still in its infancy, the quad branch-merge junction is able to handle quite a load of large trains (20 cars) with very few backups. (Figure A)

Figure A.

Speculation of angled track in the nightly builds under existing bridges will allow at least a 50% increase in train speed; eliminating eight turns that currently reduce it to below 100mph (161km/h). The sharpest turns are illustrated in Figure B:
