RF Mainline

RailForge Flagship HO Scale Model Railroad Layout

RF Mainline is the RailForge flagship: a prototype-based HO scale layout modeling active CSX railroading across Southwestern Pennsylvania — the Pittsburgh, Pittsburgh & Western, Keystone, and Somerset & Cambria subdivisions. It's where every lesson from the Five Pillars — Engineering, Systems, Fabrication, Realism, and Workshop — comes together in one continuous build: benchwork and track geometry engineered for reliability, DCC power and automation wired as real systems, custom parts fabricated in-house, and scenery weathered for believable depth. The whole layout is documented in the open, so you follow the reasoning behind each design decision, not just the finished scene.

Overview

The Cookout After Dark

An HO scale 12x12 backyard cookout where two Arduino systems run the night: a glowing burn barrel and a house that lights its own rooms. Make it real.
