Cog Railway Ridge Tunnel Under Starlit Night Sky

Steel rails curve sharply from a dark tunnel mouth onto a stone causeway, disappearing into the distance under a canopy of dense stars. The tracks gleam with a cold, metallic sheen, reflecting the faint ambient glow rising from the valley floor below. Above, the sky is a void of deep indigo, punctuated by thousands of sharp points of light. Sparse, hardy grasses rest on the rocky embankment beside the tracks, their tips catching the starlight. The tunnel entrance is a jagged black rectangle against the lighter night horizon. One rail joint glints brightly where the starlight strikes the metal edge, anchoring the heavy industrial structure to the quiet, high-altitude landscape.
