An authentic vintage 1979 reference book and instruction guide dedicated to O / O-27 Scale (1:48 scale) model train layouts. This highly illustrated manual is packed with classic track blueprints, wiring schematics, and structural operation instructions for multi-train layouts, including setups featuring the K-Line K-4 track geometries.

Sourced from the estate of a long-time model railroading collector, this manual is an excellent historical resource for anyone building, wiring, or restoring a traditional analog 3-rail model train display from the late 1970s or postwar era.
