What are the different types of railroad clips?
Common types of railroad clips include E-type, SKL, KPO, and Nabla, which are all part of various rail fastening systems used to connect rails to sleepers. Other types are designed for specific applications, such as Deenik clips for concrete sleepers, and crane rail clips for cranes.
Common types
- E-type rail clips: One of the most common types, used in various E-type fastening systems.
- SKL rail clips: A widely used system, which includes variations like SKL3, SKL12, and SKL14.
- KPO rail clips: A strong clamping system used for both standard and crane rails.
- Nabla rail clips: Another type of elastic rail clip used in some fastening systems.
Other types
- Deenik rail clips: Often used in South America, especially on concrete sleepers, for their ability to maintain gauge even in high temperatures.
- Crane rail clips: Specifically designed for crane rails, with KPO clips being a common example.
- Fast clip fasteners: A general term for clips like the high-speed Fast Clip, which are designed for specific applications.
- Bolted and welded clamps: These are distinct from elastic clips and are installed using a bolt or by welding.

Production Processes of Elastic Rail Clips
Rail clip processing procedures includes:
- Raw material purchasing
- Shearing
- Heating to forging temperature
- Forming
- Hardening
- Tempering
- Surface treatment
- Inspection-Packing
To produce rail clips usually use spring steel bar as the raw materials, before heating, raw materials must be sheared according to the length required. Then they are heated to 950℃ to 1000℃, next works transfer the heated bar to power press for forging, in accordance with drawing three sets of dies and fixtures are kept before hammering. The following procedure is to convey the forged rail clips to quenching tank. Then check the dimensional accuracy and quench hardness of the rail clips. The next procedure is tempering to achieve appropriate toughness in the spring. And the final step is to pack the rail clips after serious inspection.
