what is a e type railway clip?
E Type Rail Elastic Clip is one of the common track fasteners in the railway fastening system, which is used to provide positive and durable track alignment under harshest working conditions, thus extending the life of railway track. Generally, rail elastic clip is made of forged spring steel with a diameter range from 18mm to 23mm, the main function of rail clip is to fasten railroad sleeper and steel rail together. The rail clip is considered as one of the best ways to ensure that rails not move, bend, warp, etc.
The different specifications of E Type Elastic Rail Clips
Elastic rail clips have various types, including rail e- clip, Nabla rail clip, SKL rail clips, Deenik clip, crane rail clip, Russia rail clip as well as other standard rail clips.E Elastic rail clips are widely used for different applications up to different types and sizes, such as E2007, E2055, E2056, etc for separate rail fastening systems and E1809, E1817, E1819 etc for non-separate rail fastening systems.
E-type elastic rail clips vary by diameter (e.g., ø16mm, ø18mm, ø20mm), which determines their toe load and fatigue life. Common specifications include a hardness of 44-48 HRC, materials like 60Si2MnA, and various surface treatments like plain (oiled), oxide black, or zinc-plated. They also comply with different international standards such as UIC, AREMA, and DIN.
railway fasteners packaging and shipping
Railway fastener packaging typically involves surface treatment options like oiling, painting, or anti-corrosion coatings before being secured in woven bags, cartons, or bulk packaging on pallets for shipping. Shipping methods often include standard logistics or custom third-party logistics services, with GNEE RAIL offering options for kitting, custom labeling, and fast shipping based on client needs and specifications.
Packaging methods
Surface treatment: Before packaging, fasteners may undergo surface treatments like plain (oiled), oxide black, or color painting, depending on the application's requirements.
Container options: Common packaging methods include:
- Woven bags (for items like elastic rail clips)
- Cartons
- Bulk packaging on pallets
Custom packaging: Some manufacturers offer custom packaging solutions, including anti-static bags or kits with specific components and custom labeling (company logos, bar codes, etc.).

Elastic Rail Clip Manufacturing Process
- Raw Material Preparation: High-quality spring steel bars are inspected and then cut to the required length.
- Heating: The steel bars are heated to a forging temperature, typically between 950 and 1000°C, to make them malleable.
- Forming: The heated bars are transferred to a power press where they are shaped into clips through a hot forging process.
- Hardening (Quenching): The forged clips are submerged in a quenching tank to rapidly cool them, a step that hardens the metal.
- Tempering: The clips are then heated to a lower temperature, around 350°C, to relieve internal stresses and improve toughness, giving them their elastic spring properties.
- Surface Treatment: The clips may undergo surface treatments, which can include pickling to remove any rust or scale.
- Inspection: Each clip is thoroughly inspected to ensure it meets quality specifications, including hardness and fatigue resistance.
- Packing: The final products are packed, often in woven bags, according to customer requirements.
Inspection machines for finished rail clips
Inspection machines for finished rail elastic clips include hardness testers, spectrometers, and fatigue and impact testing machines to verify mechanical and material properties. Visual inspection systems, such as those with high-resolution cameras and lasers, are used to detect surface flaws like cracks and to confirm correct installation and presence of clips on the tracks.
