For the latest addition to the Morris Arboretum’s annual Garden Railway exhibit, designer Paul Busse looked oceanward — to America’s historic lighthouses.

Some of the best-known of these treasures, such as Massachusetts’ Brant Point Light (photo), have joined the historic houses and Philadelphia landmarks on display at the Arboretum’s summer crowd-pleaser. And tying them all together, of course, are the trains — scale models of vintage and state-of-the art equipment, winding their way over structures of sticks and leaves.
