Other Features
Section size:
Rail head: with a width of 70 millimeters, it provides the main contact and bearing surface for the wheels.
Rail waist: with a thickness of 15.5 millimeters, it connects the rail head and rail bottom and mainly bears the bending stress of the steel rail.
Rail base: with a width of 132 millimeters, it contacts the rail sleeper or track bed and transfers the load borne by the rail to the rail sleeper and track bed.
Rail height: The vertical distance from the bottom of the rail to the top of the rail head is 152 millimeters, which determines the vertical bearing capacity of the rail and its fit with the wheels.
Length dimension:
Standard track: There are two lengths, 12.5 meters and 25 meters, suitable for laying most straight and curved tracks with larger radii.
Shortened track: When used for laying under curved tracks, there are various lengths such as 12.46 meters, 12.42 meters, 12.38 meters (12.5 meters shortened track), and 24.96 meters, 24.92 meters, 24.84 meters (25 meters shortened track) to meet the laying requirements of curved tracks.
