Object
Mine Donkey Engine
A compact, industrial steam engine bolted to the engine house floor, its brass fittings gleaming despite layers of coal dust. A flywheel spins lazily, casting shifting shadows across the cramped chamber as pipes hiss with escaping steam. Heavy riveted plating protects the piston rods, their rhythmic clatter rising over the groaning timbers of the colliery. The Doctor uncouples the drive belt with practiced efficiency, assigning rugged purpose to the machine originally meant for hauling ore carts. Its boiler pressure gauge flutters near the red line, laboring under the strain of powering both the pulley lift and the heavier rescue cage.

Purpose
To provide auxiliary mechanical power for colliery operations, repurposed here as the motor for an emergency pulley system using a second cage to evacuate trapped miners.
Significance
Becomes the critical pivot between failure and rescue—the only available power source after structural collapse of the primary lift system forces the team into desperate improvisation that exposes industrial neglect central to the colliery's operation.
