Iron Beast Express.

A massive steampunk locomotive thundering down brass-railed tracks through a mountain pass, its boiler glowing cherry red with internal furnace heat. Oversized copper pipes and pressure valves adorn the engine body, releasing jets of white steam. The cowcatcher is shaped like a fierce eagle head in blackened iron. Glowing headlamp cuts through swirling mist as pistons drive enormous spiked wheels forward relentlessly.
