Why Use Rail Braces in Railway Tracks?

Prevent Rail Roll:

Braces (also called rail shoulders) resist lateral forces from trains, especially on curves.

Maintain Gauge Stability:

Keeps rails at correct spacing, reducing wear on wheels and track.

Absorb Dynamic Loads:

Reduces vibration and track deformation under heavy axle loads (e.g., 30+ ton freight cars).

Where Are They Essential?
Sharp curves (radius < 500m)

Heavy haul lines (coal, ore transport)

High-speed tracks (lateral forces increase with speed)

Types of Rail Braces:
Fixed Braces: Bolted directly to sleepers (used in rigid tracks).

Adjustable Braces: Allow for thermal expansion (common in continuously welded rail).
