E-Clip Railway Fastening System
E clip rail fastening system
E clip Fastening System is a mature, versatile solution and is widely used across the world. It has the advantages of boltless design, easy installation, stable clamping force and low maintenance. Our e clip system is widely used in heavy-haul railways, mainline railways, urban metros, high-speed lines and ballasted tracks with concrete or wood sleepers.
The E-Clip is one of the most common solutions for fastening rails to their base. It is E-shaped, featuring flexible and firm connections to ensure safe and smooth track operation. We supply various elastic rail clips in different sizes. For separate rail fastening systems, we offer E2001, E2003, E2006, E2007, etc; for non-separate rail fastening systems, we provide E1609, E1806, E1809, etc. We can supply all rail fasteners for types of rail fastening system. Feel free to contact us.

E-clip railway fastening system types
Our e-clip rail fastening systems are available in various designs. Below are two typical models: E-clip fastening system with steel base plate, "Pandrol" E-clip fastening system.
1. "Pandrol" E-clip fastening system
This E-clip fastening system has a simple structure, requires no maintenance, provides excellent lateral resistance and is highly cost-effective. It is ideal for large-scale installation on heavy-haul freight lines and conventional ballasted tracks.
Components:
Item Included | Quantity | Material |
E Clip | 2 pcs | 60Si2MnA, 60Si2CrA |
Shoulder | 2 pcs | QT500-7, QT450-10 |
Rail Pad | 1 pc | HDPE, rubber or EVA |
Insulator | 2 pcs | Reinforced Nylon 66 (PA66) |
Wide application:
This E-clip fastening system is primarily used for:
1. Mixed passenger/freight heavy-haul lines & high-capacity ballasted tracks (speed ≤ 160 km/h)
2. Coal & ore heavy-haul lines, max axle load 25 tons
3. Standard trunk lines with large track maintenance machinery
4. Plain-area tracks with stable beds and no visible settlement
2. The E-clip system with iron base plates
The E-type clip system with iron base plates uses a double-layer elastic design to reduce vibration and noise. It offers smoother train passage, reliable insulation and flexible height and gauge adjustment, and is widely used in metro lines.
