A spline of 2 vertical parallel steel girders held at standard gauge separation by 4 tranverse members in 28ft sections. The girders are composed of welded 3ft square steel plates. A single unballasted standard-gauge track lies on top of the girders.
A suggested pier to use is <kuid:368725:20497> 'bridge pier, brick, 10m'. For bridge abutments use <kuid:368725:20499> 'bridge abutment, single track, type 1'.
Where the bridge is on a curved track, user <kuid:368725:30169> 'NSW steel box girder bridge, no track' and fit this under the curved track.
