About
A 12 m single track viaduct span: a prestressed concrete box girder with cantilever deck edges on a tapered pier and spread footing, carrying ballasted track between 1.15 m parapets with a cable trough and walkway each side. The pier base sits at y=0 and the railhead at y=7.80, so spans chain to each other rather than to ground level track. The module origin sits on the rail-a port at the deck centreline. Bounding size 5.00 x 8.38 x 12.00 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Static geometry; no rig, collision or navigation data.
