50E6 Rail
Product Overview
The 50E6 rail (also called U50)is a premium-grade heavy rail profile engineered to meet the most demanding requirements of ultra-heavy haul freight, urban transit systems, and industrial heavy-duty applications. Compliant with EN 13674-1 (mechanical properties) and EN 13674-4 (dimensions), this rail offers a unique balance of strength, durability, and dimensional precision.
Key Features
Dimensions:
Weight: 50.9kg/m (112.22 lb/yd)
Head Width: 65 mm | Rail Height: 153 mm | Base Width: 140 mm | Web Thickness: 15.5 mm
Length: customized from 5m to 25m.
Material & Mechanical Properties
Standards: EN 13674-4 (dimensions), EN 13674-1 (mechanical properties), ISO 9001:2008 (quality management).
Steel Grades:
R200: 200–240 HBW hardness, ≥680 MPa tensile strength; suitable for light-duty regional lines.
R260: 260–300 HBW, ≥880 MPa tensile strength; engineered for mainline freight (axle loads ≤25 tons).
R260Mn: Enhanced manganese content (1.30–1.70%) for abrasive environments like mining.
R350HT (heat-treated): 350–390 HBW, ≥1175 MPa tensile strength; optimized for ultra-heavy haul (30+ ton axles) and high-speed applications, reducing wear by 25% compared to non-treated grades.
Customization Services
Rail Processing: Pre-drilled bolt patterns (M24–M30), stress-relieved end machining, and mill-certified weld preparation.
Accessories:
Rail clamps
Fish Plates & bolts for secure 50E6 rail joints.
Rail Pads: 5–15 mm thickness for vibration damping in passenger lines.
Applications
Heavy Haul Freight Networks
Supports axle loads up to 35 tons in bulk cargo transport (e.g., coal, ore, grain), with R350HT grades excelling in long-distance corridors.
Urban Transit Systems
Critical for metro and light rail networks (e.g., London Underground, Paris Métro), where R260 grades provide smooth rides and reduced noise emissions.
Engineered for repetitive loading from high-frequency passenger trains, ensuring longevity in densely populated urban areas.
Mining & Quarry Systems
Resists deformation from uneven track beds and abrasive ore cart wheels in underground mines (e.g., copper mines).
R260Mn grade preferred for surface quarry rails, withstanding repetitive loading/unloading of gravel/stone.
Ports & Intermodal Terminals
Deployed in container gantry cranes (40+ ton loads) in hubs , with galvanized 50E6 rails resisting saltwater corrosion.
Integrates with automated guided vehicle (AGV) systems for precision cargo movement in warehouses.
