Tie Plates 115RE In Railway

115RE tie plates are heavy-duty steel components designed to support AREMA 115RE rail (nominal weight of 115 lb/yd) on railroad ties. They serve as a critical interface between the rail and the sleeper, distributing the load from moving trains to a larger area to protect the ties from excessive wear and "cutting".

Key Specifications

Dimensions: Commonly available in lengths of 11 inches, 14 inches, and 14-3/4 inches.

Weight: A standard 14-inch plate typically weighs approximately 22.19 lbs (non-ribbed) to 23.12 lbs (ribbed). Some variants may weigh roughly 10.6 kg (~23.3 lbs) per piece.

Shoulder Type: For 115RE rail, double shoulder plates are standard to prevent lateral movement in both directions.

Cant: Typically manufactured with a 1:40 cant (slope) to tilt the rail inward, ensuring better wheel-to-rail contact and stability.

Materials: Often made from cast iron (ductile or nodular) or forged/rolled low-carbon and high-carbon steel (e.g., QT450-10, Q235, or 45# steel).

Primary Functions

Load Distribution: They transfer the vertical load from the steel rail to the ties, preventing the rail from sinking into the wood or concrete.

Gauge Maintenance: The shoulders and pre-drilled spike holes hold the rail firmly at the correct distance (gauge).

Tie Protection: By providing a smooth, flat resting surface, they reduce friction and protect sleepers from damage caused by rail vibrations. 

115RE tie plates are widely used across North and South America for mainline freight, mining tracks, and heavy-haul railway systems. 

Common AREMA Plan Specifications for 115RE

AREMA 115RE tie plates are categorized by Plan Numbers that define their length and weight to match specific track requirements. Plan 8 and 12 are the most common standards for 115RE rail. 

Signum specializes in AREMA tie plates, specifically for 115RE or 136RE rail sections. We currently support North American infrastructure projects by providing forged,rolled and cast plates that meet Plan 8 and Plan 12 specifications.We’d love to send over our latest technical data sheets and lead times for your maintenance cycle if you need.
