Comparison: E2007 vs. E2009 Elastic Rail Clips

The E2007 and E2009 are specific types of E-type elastic rail clips, essential forged spring steel fasteners used in railway track systems (like Pandrol clips) to securely hold rails to sleepers (ties) for track integrity, allowing for necessary expansion and contraction while providing superior holding power, often compared to simpler C-clips due to their design, and fitting various sleeper

Here’s a clear, side‑by‑side comparison of the E2007 and E2009 Elastic Rail Clips, focusing on the key technical and application parameters that matter most for buyers, engineers, and rail product specifiers.

Key Practical Differences

1. Clip Geometry

E2007 and E2009 are both elastic clips, but they have slightly different curvature, heel width, and toe spacing to match specific baseplates or track designs.

This means they are not always interchangeable — the correct type must be matched to the specific fastening system or baseplate design you are using.

2. Application Fit

In many rail fastening catalogs, E2007 fits older or particular baseplate designs, while E2009 fits others. The difference is subtle but important for proper rail seating and clamping force.

Always refer to design drawings from the fastening system manufacturer to ensure correct clip selection.

3. Supplier Variation

Although the material and basic performance are similar, manufacturers will often adjust the clip shape and spring performance for specific market conditions (e.g., heavy freight vs. passenger service, high vibration needs, regional standards).

Quick Selection Guide

Use this flow when choosing between E2007 and E2009:

• Check Baseplate / Sleeper Design

• Are the clip pockets or shoulders designed for E2007 or E2009?

• Match the clip to the baseplate.

• Check Rail Profile

• Ensure the rail profile (e.g., UIC60, AREMA 136RE) is supported.

• Check Load Requirements

• Confirm clamping force and fatigue requirements.

• Check Environment

• Choose surface treatment (galvanized / painted / black oxide) based on climate.

• Confirm Standards

• Ensure the clip meets customer/railroad standards (GB/T, DIN, UIC, AREMA).

Summary — E2007 vs E2009

Aspect                       Main Point

• Material                 Same spring steel class

• Performance         Similar elastic & fatigue properties

• Geometry       Different shapes; match to baseplate

• Function       Same clamping principle

• Application       Similar, but design dependent

• Standards       Both can be made to international standards
