High - Speed Railways typically adopt heavy - duty and high - precision steel rails, such as those with a weight of 60 kg/m or above. The fastener systems for high - speed railways are more sophisticated and complex. Take the Type IV and Type V elastic rail fasteners as examples. They can provide higher clamping forces to ensure a tight connection between the steel rails and sleepers. Meanwhile, they possess excellent elasticity and insulation properties.
