The Walthers Cornerstone 933-4511 is a 97-foot single-track Warren Truss bridge — a classic standardized steel span used by railroads worldwide where extra overhead clearance is needed below the deck. As part of the Cornerstone Engineered Bridge System, it lines up cleanly with matching piers, abutments, and other bridge spans for a finished, layout-ready scene.

FAQ

Will modern double-stack cars clear this bridge?Yes. The bridge offers a scale 22' (6.7m) of clearance, which clears double-stack container cars and other tall modern equipment.
Does it work with other Cornerstone bridges and piers?Yes — it's part of the Cornerstone Engineered Bridge System and is dimensionally matched to Cornerstone piers, abutments, and bridge spans.
What era is this bridge suitable for?The Warren truss has been a standard railroad bridge design since the late 1800s and is still in service today. It works equally well on steam-era, transition-era, diesel-era, and modern layouts.
