What is the specification of UIC54 railroad?
The UIC54 rail (also officially designated as the 54E1 profile under modern European standards) is one of the most widely implemented steel rail profiles globally, engineered specifically for main-line passenger railways, medium freight transit, and urban metro systems. Characterized by its specific mass and highly optimized geometry, the UIC54 specification ensures excellent load distribution and long-term track stability.

| UIC54 | UIC | 159,00 | 140,00 | 70,00 | 16,10 | R200, R260, R260MN, R350HT | 54,77 |
GNEE RAIL is a professional steel rail supplier. We can supply a variety of rails, including light rails, heavy rails, crane rails and other different standards and specifications.
Material Grades and Steel Composition of UIC54 Rail Profile:
Common grades specified for UIC54 include R200,R260 (standard carbon steel with a tensile strength of over 880 MPa), R320Cr (chromium-alloyed for enhanced wear resistance), and R350HT (heat-treated for maximum hardness and fatigue life).

Standard Lengths and Manufacturing Tolerances
UIC54 rails are typically manufactured in standard lengths of 12m, 15m, 18m, and 25m, though modern continuous welded rail (CWR) projects often require longer lengths up to 100m, depending on transportation feasibility.
As a comprehensive railway track solution provider and a direct manufacturing factory, GNEE RAIL ensure that you are not simply buying steel, but investing in a complete, reliable, and safe track ecosystem. Beyond manufacturing UIC54 rails in fully customized lengths, our facility produces perfectly matched rail accessories, including fishplates, rail clips, and tie plates, ensuring 100% structural compatibility.
