Tb Two Line Vert Seam

Gallery / TB / BT Sections

A vertical-flow section's RIGHT exit feeds another vertical-flow section's LEFT entry with a two-line bundle. The entry sits a station gap above the trunk head so both lines enter horizontally then drop straight onto their trunk lanes, rather than the staggered line slanting into the trunk for want of drop room (#1054).
