The NNRW maintenance shed is a treasure trove of historical and functional artifacts essential for preserving steam locomotives. Inside, you'll find a variety of tools, from wrenches and hammers to specialized equipment like oil cans and grease guns, all organized in creative chaos. The shed houses spare parts for engines and carriages, including wheels, axles, and boiler components. Workbenches are cluttered with nuts, bolts, and blueprints detailing the intricate workings of steam engines. Lathes and milling machines stand ready for fabricating hard-to-find parts. This bustling hub is where skilled volunteers and staff meticulously maintain and restore the museum's historic railway equipment.
