the dimensions of Railroad tie plate
Railroad tie plate, also called base plate or sole plate, is a kind of steel plate used between the rails and sleepers on rail tracks. Tie plate is usually tapered on the sleepers by rail bolts or rail spikes through the holes in the plate.
Railroad tie plate dimensions vary by type, but common US sizes are 11, 14, and 14-3/4 inches for 5-1/2 or 6-inch rail bases, while European standards like UIC and AREMA have different sets of dimensions. Key dimensions include the overall length, which corresponds to the rail base size, and the width and thickness, which are often listed in a series of numbers (e.g., 370/310/152x160x15/13). The plates also have specific features like the number and diameter of spike holes and a rail seat cant angle, typically 1:40.
US (AREMA) standards
- Common lengths: 11 inches, 14 inches, and 14-3/4 inches.
- Rail base compatibility: These lengths are typically for 5-1/2 inch and 6-inch rail bases.
- Features: Plates for larger rails may use double shoulders, while single shoulder plates are used for smaller rails.
European standards (e.g., UIC)
Examples of dimensions:
- Rph 6/160: 370/310/152 x 160 x 15/13 mm
- Rph 6/210: 370/310/152 x 210 x 15/13 mm
- SZ 60: 370/350/152 x 420 x 15/13 mm
- Rph 11 Ü: 664/554 x 160 mm
- Rph 13 Ü: 690/570 x 160 mm
Key dimensions and features to note
- Length: The first number in a series (e.g., 370 mm) is often the rolled width, which equals the tie plate's length.
- Width and thickness: The remaining numbers indicate the width and thickness, respectively (e.g., 310/152 x 160 x 15/13 mm).
- Rail seat cant: A built-in angle (like 1:40) that tilts the rail toward the track's center to offset lateral thrust.
- Holes: The number, shape (round or square), and diameter of spike holes are specific to the plate type and rail it's designed for.
