55E1 Rail
Product Overview
The 55E1(often called “U 55” in older national standards) rail is a heavy-duty railway rail profile primarily used in specialized heavy haulage, industrial, and urban transit applications.55E1 steel Rail is a kind of EN standard heavy rail. It is an uncommon rail type.
Key Features
Dimensions:
Weight: 56.03kg/m ( 123.52lb/yd)
Head Width: 62 mm | Rail Height: 155 mm | Base Width: 134 mm | Web Thickness: 19 mm
Length: customized from 5m to 25m.
Material & Mechanical Properties
Standards:Dimensions: EN 13674-4 (custom variant).
Mechanical properties: EN 13674-1 (R260/R350HT grades).
Steel Grades:
R260 Grade:
260–300 HBW hardness, ≥880 MPa tensile strength; suitable for general freight and industrial use with axle loads up to 25 tons.
R350HT Grade:
Heat-treated for 350–390 HBW hardness and ≥1,175 MPa tensile strength, ideal for ultra-heavy haul (30+ ton axles) and high-speed applications. This grade reduces wear by 25% compared to non-treated rails.
Customization Services
Pre-drilled bolt patterns, stress-relieved ends, and corrosion protection (galvanization or epoxy-polyester paint).
Due to 55E1 is not a universally recognized EN standard. The minimum order quantity(MOQ) is 1,000 tons.
Accessories:
Rail clips
Rail Pads
Fish Plates & bolts for secure 55E1 rail joints.
Applications
Heavy Haul Freight Networks
Supports axle loads up to 35 tons in bulk cargo transport (e.g., coal, ore), with R350HT grades excelling in long-distance corridors.
Used in double-stacked container trains, aligning with AAR M-101 requirements.
Industrial & Mining Systems
Resists deformation from uneven track beds and abrasive ore cart wheels in underground mines.
R260Mn grade (enhanced manganese content) preferred for surface quarry rails .
Ports & Intermodal Terminals
Deployed in container gantry cranes (40+ ton loads) in hubs, with optional galvanized coatings (85μm Zn) for saltwater resistance .
Urban Transit Upgrades
Used in light rail systems requiring higher stability than 54E1.
Suitable for metro networks with increasing passenger loads (e.g., Underground extensions).
