A sophisticated and intricately designed steam locomotive, featuring a maze of polished brass gears and valves, with a network of copper pipes weaving through its chassis. The engine's body is adorned with ornate engravings, shimmering under the light as plumes of steam emerge gracefully from its chimney stack, merging with the rhythmic churning of its powerful pistons. Its massive iron wheels, precision-crafted and etched with filigree, turn in perfect harmony, while the cabin glows warmly, housing a complex array of gauges and levers, each with its own unique function in maintaining the beast's elegant yet formidable presence on the iron tracks.
