[Description: A rhythm-driven industrial piece built from the sounds of a steam locomotive. Wheels on tracks create a steady, hypnotic pulse, while metal percussion mimics the clanking of machinery. A distant whistle and steam bursts punctuate the groove. The music evokes the power and motion of an old train hurtling down the line.]
