Expand your bridge infrastructure with this essential expansion kit designed specifically for the Concrete and Girder Bridge #9005. Create double or triple track bridges to accommodate busy mainlines and complex railroad operations on your N scale layout.
Modular Bridge System
The Concrete and Girder Bridge is a modular bridge system that can be combined with this Expansion Bridge Kit to create multiple configurations:
- Double track bridge - Combine one #9005 base bridge with one #9006 Expansion Kit
- Triple track bridge - Combine one #9005 base bridge with two #9006 Expansion Kits
- Even wider spans - Add additional expansion kits for four or more tracks
- Flexible configuration - Build exactly the bridge width your layout requires

Technical Specifications

Applications & Layout Ideas
This expansion kit enables you to create realistic multi-track bridge scenarios:
- Double-track mainlines - Model busy railroad corridors with parallel tracks
- Passing sidings on bridges - Create operational flexibility on elevated structures
- Triple-track terminals - Detail complex urban railroad approaches
- Yard lead bridges - Model multiple tracks entering classification yards
- Industrial access - Create multi-track bridges serving factories and facilities
- Commuter rail operations - Model suburban railroad infrastructure
Assembly & Integration
The expansion kit is designed to integrate seamlessly with the base Concrete and Girder Bridge #9005. Assemble the abutments according to the included instructions, then position them adjacent to your base bridge. Install the white metal girders to create the additional bridge deck. The modular design ensures perfect alignment and a cohesive appearance across the entire bridge structure. Multiple expansion kits can be added side-by-side to create even wider bridges.
Painting & Finishing
Paint the gypsum components to match your base bridge #9005 - use consistent gray tones for concrete to create a unified appearance across the entire structure. The metal girders should match the base bridge girders in color and weathering. For realistic results, weather all components together as a single structure, adding rust staining, concrete discoloration, and environmental effects that span across all sections. This creates the appearance of a single integrated bridge rather than separate components.
Planning Your Bridge
Before purchasing expansion kits, plan your bridge configuration:
- Single track: Base bridge #9005 only
- Double track: One base bridge #9005 + one expansion kit #9006
- Triple track: One base bridge #9005 + two expansion kits #9006
- Four or more tracks: One base bridge #9005 + three or more expansion kits #9006
Required Base Bridge
Important: This is an expansion kit only. You must have the Concrete and Girder Bridge #9005 to use this expansion kit. The expansion kit cannot be used as a standalone bridge.
