Description

Technical Field

[0001] The utility model relates to the technical field of railways, in particular to a vibration-reducing railway track. Background Art

[0002] Railway transportation is a land transportation method that uses locomotives to pull train vehicles on two parallel rails. The traditional method is to use steel wheels to travel. The rails can provide an extremely smooth and hard medium for the train wheels to roll on with minimal friction, making people on them feel more comfortable and saving energy. However, the existing rails are usually fixed with fasteners with W-shaped spring bars. When a train runs on the rails, the rails sink slightly and there is a slight gap between the rails and the fasteners. The repeated deformation between the rails and the fasteners causes vibration, which not only affects the running quality of the train, but also causes a lot of noise. Utility Model Content
