Elle paused, glancing at her sister with a mix of excitement and curiosity. "Do you see that, Avery? It's like something out of a storybook." Avery nodded, brushing aside vines to reveal the shed's entrance. "I wonder what's inside," she mused, her voice barely above a whisper. With a shared look of determination, they pushed the door open, revealing the shadowy interior and the silent giant within.

Elle's eyes widened in recognition. "Avery, it's Grandfather's locomotive!" Avery approached the engine, running her fingers over the cold metal, a smile tugging at her lips. "Alder," she breathed, remembering the stories their grandfather used to tell. The sisters exchanged a glance, understanding passing silently between them. They knew what they had to do.

Elle wiped sweat from her brow, her hands greasy from the work. "This is going to take time, but it'll be worth it," she said, a note of certainty in her voice. Avery nodded, her focus on a blueprint spread across a table. "Every bolt and every rivet will bring us closer to him," she replied, her eyes bright with resolve. Their days were filled with hard work and laughter, each task a step closer to bringing Alder back to life.

Elle paused, holding up a photograph of their grandfather beside Alder, his smile warm and proud. "He'd be so happy to see this," she murmured. Avery joined her, resting a hand on Elle's shoulder. "We're doing this for him, and for us," she said softly, a bond stronger than ever between them. The sisters shared a moment of quiet reflection before returning to their work, driven by love and legacy.

Elle and Avery stood side by side, eyes shining as they admired their work. "We did it, Avery. Alder is ready," Elle said, her voice full of pride. "It's more beautiful than I imagined," Avery replied, a tear of joy slipping down her cheek. The sisters climbed aboard, hearts full of anticipation as Alder's engine rumbled to life once more.

Elle grinned, her hands steady on the controls. "Here's to new journeys and honoring the past," she declared. Avery nodded, her heart full of gratitude and hope. "And to the memories we'll create with Alder," she added, her voice ringing with excitement. Together, they steered the locomotive into the horizon, a tribute to their grandfather and the indomitable spirit of family.
