What is the detailed uic54 rail specification?
UIC54 rail is a standard heavy rail profile defined by UIC 860, widely applied in mainline railway systems for both passenger and freight transport. With a theoretical weight of 54.43 kg/m, it offers a balanced combination of strength, wear resistance, and cost efficiency.
uic54 rail dimensions:
The UIC54 rail specification is defined by its cross-sectional geometry and mechanical properties. These parameters directly affect load-bearing capacity and service life.

| EN 13674 - 1 (2006) | ||||
| R200 | min 680 |
14 | 200 - 240 | |
| R260 | min 880 |
10 | 260 - 300 | |
| R260 MN | min 880 |
10 | 260 - 300 | |

How Does uic54 rail profile Compare with Other Rail Types?
UIC54 rail is a standard heavy-duty rail profile (54.77 kg/m) widely used in Europe and Asia for mainlines, offering high endurance for heavy loads (> 25 tonnes axle load) and high-speed passenger lines up to 120--160 km/h. Compared to lighter rails (e.g., 50 kg/m), it is more durable; compared to heavier UIC60 (60.21 kg/m), it is lighter, offering a better balance of cost and performance for medium-heavy traffic, though with less stiffness.
Key Comparisons with Other Rail Types:
- vs. UIC60 (60E1): UIC54 is lighter (54.77 kg/m vs 60.21 kg/m), making it slightly less rigid and less suitable for extremely high-speed (> 200 km/h) or ultra-heavy hauling compared to UIC60, which provides better resistance to bending and fatigue.
- vs. AREMA/American Rails: UIC54 is a metric, standardized profile (standardized under EN13674-1) focused on European/Asian standards, while American 136RE or 141RE rails have different head, base, and fishing geometries, leading to different fastening system compatibilities.
| Type of Rails | Dimensions (mm) | Weight (kg/m) | Steel Grade | |||
|---|---|---|---|---|---|---|
| Rail height (A) | Bottom Width (F) | Head Width (C) | Web Thickness (t) | |||
| 90ARA-A (TR45) | 142.9 | 130.2 | 65.1 | 14.3 | 44.65 | Standard Strength (SS) Intermediate Strength (IS) High Strength / Head Hardened (HH) |
| 100RE | 152.4 | 136.5 | 68.3 | 14.3 | 50.34 | |
| 115RE (TR57) | 168.3 | 139.7 | 69.1 | 15.9 | 56.9 | |
| 119RE | 173.1 | 139.7 | 67.5 | 15.9 | 58.86 | |
| 132RE | 180.9 | 152.4 | 76.2 | 16.6 | 65.58 | |
| 133RE | 179.39 | 152.4 | 76.2 | 17.46 | 66.1 | |
| 136RE (TR68) | 185.7 | 152.4 | 74.6 | 17.5 | 67.5 | |
| 141RE | 188.91 | 152.4 | 77.79 | 17.46 | 69.94 | |
- vs. Lighter Rails (e.g., 50 kg/m): UIC54 offers superior durability, enhanced wear resistance, and higher axle load capacity, making it a better choice for high-density traffic.
