Under the mountain switchyard roof, Tessa tightened the last brass screw with fingers smelling of oil and warm metal. She had given herself until moonrise to build a smoke-shaper no bigger than a lunch pail, one that could twist steam into a secret sign. The night trains needed it; fog often swallowed the red signal post, and wheels hissed too close to the cliff curve.
Her obstacle was the chimney’s roar. Every test puff burst apart—whoof, whoof—into plain gray clouds. Tessa pressed her ear to the boiler, heard the little rattle hiding beneath the thunder, and grinned. “You’re knocking because you want a rhythm,” she whispered. She bent a strip of copper into three tiny fins and fitted them inside the stack by lanternlight.
At moonrise, the engine rolled out, bell trembling, headlamp bright as a coin. Smoke climbed, curled, and formed one tall question-mark swirl over the track. The engineer saw it, slowed, and found a fallen pine beyond the bend. Ever since, steam trains have worn puffing plumes above their chimneys, and if you study this engine’s smoke, you might spot Tessa’s first secret swirl.
