Bailey Base Bus May 2026

Would you like a specific wiring diagram for a 3‑module Bailey setup, or guidance on choosing connectors for outdoor/garden railway use?

In a Bailey modular layout, the Base Bus is the main power distribution backbone. Unlike a conventional layout where one thick wire runs under the entire board, a Bailey system uses multiple modules (typically 1200mm x 600mm or smaller) connected end-to-end. The Base Bus ensures consistent power and data (for DCC) across all module joints. bailey base bus
