Section Trunk Short Output Branch

Gallery / Off-track & Rails

A section holding a long main chain plus a short branch to an off-track output file. The long chain rides the section trunk straight and the short output branch peels off it, rather than the short branch taking the trunk and forcing the main chain onto a diagonal that crosses it (issue #1487).
