Model Railroad Project Planner & Scenery Materials Inventory — Two Low-Competition Medium-Content KDP Niches

Model railroading is a detail-driven hobby where builders need repeatable systems: project sequencing, wiring notes, parts sources, and material reuse. This episode presents two complementary medium-content KDP books that solve those routine pain points: (1) a Model Railroad Project Planner for staging builds, wiring diagrams, and parts lists; (2) a Scenery Materials Inventory & Sourcing Log to track foam, foliage, paints, suppliers, and SKU costs. I walk through data-backed demand signals (niche forum activity, micro-communities, low product coverage on Amazon), precise AI prompts to validate and expand keywords, a realistic profit breakdown for 100 monthly sales, and a launch-first checklist that authors can complete in days. Perfect for KDP creators who want practical, hobby-focused books with durable search intent and repeat purchase potential.
