This short article describes a class of rock road-sand silos: a summit fill/drop opening and a truck tunnel descending to the draw point, sometimes with a bend that avoids reversing. It provides no named unit, count, size, shaft depth, tunnel length, systems or cost, and does not substantiate alleged Cold War secondary uses.

The site commendably labels its dossier Representative Unit and avoids a national multiplier, but the SEK 74.3m base rests on an assumed 700 m² / 7,535 ft² and 4,900 m³. The wide SEK 14.3m-398.0m range demonstrates that the article cannot price a unit. It should not be in the facility ranking.

A class description only; no physical unit or national count is supported.
Retain only as an interactive archetype/reference class; remove the single base total from the master ranking; model capacity, shaft and tunnel geometry when a named unit is documented; state that the secondary-use claim is unverified
named site and count; capacity; shaft depth/diameter; tunnel length/section; rock and water conditions; loading equipment
class article is displayed in an asset archive; assumed representative unit looks like a physical estimate; enormous range is not decision-grade
