Tie plates for S49 rail are specific railway components designed to support the S49 rail profile and the entire rail fastening system, adhering to standards like UIC864-6. These S49 base plates, also called S49 sole plates, transfer wheel load from the rail to the tie (sleeper) and help maintain proper gauge by preventing the rail from cutting into the tie. Key characteristics include single or double shoulders, pre-drilled holes for spikes or anchor bolts, and a specific shape and incline (like a 1:40 slope) to match the S49 rail profile and the tie's angle.
Rail Support: The primary function of S49 tie plate is to provide a flat, uniform bearing surface for the rail to rest on.
Load Distribution: S49 tie plates distribute the wheel load from the rail across a wider area of the tie, preventing the rail from cutting into the wood tie.
Gauge Maintenance: S49 tie plates help maintain the correct distance between rails (gauge) by holding the rail in its proper position.
Fastening System Integration: S49 tie plates work with other components like rail spikes, anchor bolts, and rail clips to secure the entire fastening system to the tie.
Key Characteristics for S49 Rail
Standard Compliance: Tie plates for S49 rail often conform to UIC864-6 (International Union of Railways) standards, which define the specifications for European rail products.
Shoulder Type: They are available as single-shoulder or double-shoulder designs, depending on the specific fastening system and rail requirements.
Dimensions & Incline: The shape and dimensions of the tie plate are critical for matching the S49 rail profile. For example, the standard incline for S49 tie plates is often 1:40, ensuring the correct cant (tilt) of the rail.
Holes: The plates feature pre-drilled holes for spikes or bolts that fasten the rail to the tie.
