1. Definition & Purpose

Steel railway bridges are specialized structures designed to carry train traffic over obstacles (rivers, valleys, roads). They prioritize heavy load capacity, rigidity, and fatigue resistance due to dynamic train forces.

2. Key Design Features

  • Heavier Steel Sections: Thicker flanges/webs to withstand repetitive train loads.

  • Minimal Deflection: Strict limits (typically ≤ *L/1000*) to prevent track misalignment.

  • Fatigue-Resistant Details: Welded/bolted connections designed for cyclic loading.

  • Ballasted or Open Decks: Ballast distributes loads; open decks use direct rail fixation.

3. Common Types

TypeDescriptionExample
Plate GirderFabricated I-sections for short-medium spans (20–50m).Classic freight rail bridges
Truss BridgesWarren/Pratt trusses for longer spans (50–150m).Historic bridges (e.g., Forth Bridge, UK)
Continuous GirdersMulti-span designs to reduce joints.High-speed rail viaducts
Arch BridgesSteel arches for aesthetic/landmark crossings.Hell Gate Bridge, USA

4. Unique Challenges

  • Vibration Control: Requires dampers or mass-spring systems.

  • Thermal Expansion: Rails exert significant longitudinal forces.

  • Inspection Access: Often includes catwalks for maintenance crews.

5. Maintenance Needs

  • Frequent bolt tightening and crack inspections.

  • Corrosion protection (sandblasting + painting).

  • Ballast/deck drainage to prevent rust.
