About
A two track catenary portal: a pair of 8.4 m H section masts on concrete foundations 9 m apart, joined by a lattice cross beam with top and bottom chords and diagonal bracing, carrying insulated droppers and registration arms over each track centre at x = +/- 2.25. Bounding size 9.90 x 8.40 x 0.90 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Static geometry; no rig, collision or navigation data.
