Rail Gauge Baffle for Nabla Rail Fastening

In the Nabla rail fastening system, the gauge baffle (often referred to as a rail insulator or guide plate) is a critical component responsible for maintaining the correct distance between rails while absorbing lateral forces. 

Key Functions

• Gauge Maintenance: It holds the rails at a precise distance (typically 1,435 mm for standard gauge) to prevent derailments caused by track misalignment.

• Lateral Force Absorption: The baffle captures and distributes sideways forces from passing trains to the sleepers, protecting the clips and other fasteners from excessive stress.

• Electrical Insulation: It separates the rail from the rest of the fastening assembly to block stray electrical currents, ensuring the integrity of signaling systems.

• Adjustability: Modern variants like the Nabla Evolution allow for fine gauge tuning in 1.25 mm increments (up to ±7.5 mm per rail seat) to compensate for wear or environmental shifts. 

Material and Design

• Materials: High-strength polymers such as Nylon-66 (PA66) reinforced with 20% to 35% glass fiber to withstand heavy impacts and harsh weather.

• Variants: While most Nabla baffles are non-metallic for insulation, some industrial applications use hot-rolled steel versions (Q235-A) in systems where electrical isolation is not the primary concern.

• Integration: In a standard assembly, it is positioned directly between the rail foot and the Nabla elastic clip.
