FAQ
Does this bridge include track?
No, track is sold separately. Walthers Code 83 Bridge Track (948-886) is recommended, but the bridge will accept other Code 83 trackage.
Will modern double-stack cars clear this bridge?
Yes. The 933-4522 is designed to NMRA overhead clearance standards and will clear double-stack container cars and tall auto racks.
Does it work with other Cornerstone bridges and piers?
Yes — it's part of the Cornerstone Engineered Bridge System and is dimensionally matched to other Cornerstone piers, abutments, and bridge spans.
What era is this bridge suitable for?
Steel arched-truss bridges of this style have been in service since the early 1900s and remain in use today, so it works equally well on steam-era, transition-era, diesel-era, and modern layouts.
