Merge Adjacent Feeder
One line converges on a merge from a distant feeder and from the section next door. The distant one carries the trunk's bypass below the rows; the neighbour's hop is clear and the channel sits past its target, so it runs into the merge directly and the two fuse into one ascent rather than running parallel a bundle-gap apart (#1576).
