Type I railway spring clips: also known as ω fasteners. The elastic clip is used for track fixing and needs to maintain a certain fixed pressure and sufficient strength. For 50kg/m rails, there are two types of rail baffles, namely intermediate gauge baffle and joint gauge baffle. Each type of rail baffle is divided into two numbers, 14 and 20. Except for the B-type spring clip used for the 14-section joint baffle, the rest are equipped with A-type elastic clips. There is only one type of gauge baffle for 60kg/m rail, which is divided into 6 and 10 numbers, and the B-type railway tension clips are evenly installed.
