Tb Passthrough Continuation

Gallery / TB / BT Sections

A TB convergence that is not a sink: a diagonal feeder continues straight down to a station directly below the merge while a collinear feeder peels off. The continuation rides the trunk slot so it drops straight, instead of being forced outboard where it kinks at the merge and crosses the collinear feeder (issue #1012).
