These transition strips are designed to descend down from a Branchline height roadbed to 0 at the other end.  These will work great when needing to transition down into a yard or a spur with no roadbed from the Line.  You get two transitions with each item selected, 1-LH and 1-RH.  These Transitions include 30-degree slopes.   The strips are kerfed just over half-way on the thicker end.
