BRIO World Stacking Track Supports are a practical expansion for your BRIO wooden railway. This twin-pack adds height and versatility to BRIO train set play, letting little builders create bridges, tunnels, or stacked roadway scenes that spark storytelling as the trains chug through. Built with BRIO's renowned wooden craftsmanship, these supports feel sturdy, safe, and durable for everyday adventures. Each set includes 2 supports, sized to integrate smoothly with existing BRIO track layouts, so imagination can grow without compatibility concerns. Used with BRIO wooden railway builds, these stacking supports unlock endless layouts. Place tracks atop the supports to form bridges, or stack them higher to sculpt tunnels and multi-level routes. They’re ideal for imaginative play and for teaching early engineering concepts like balance and spacing, while strengthening fine motor skills as little hands adjust heights and link pieces.
