Fasteners Railroad Clip Fast Clip

Railway Clip is used to fasten the rails to the underlying base plate together with the concrete sleeper. A variety of different types of heavy-duty clips are used to fasten the rails to the underlying baseplate or Sleeper, one common being the E Clip, which is shaped like a stubby paperclip. Another one is the SKL Tension Clamp, which is also the most widely used type all over the world. Others like KPO Clamp and Nabla Clip, also used in different situations.

Rail Fast CLIP Fastening System

The Railway Fast Clip (proprietary name Fastclip) is a threadless, resilient rail fastening system developed by Pandrol that revolutionized track installation through its innovative "switch on-switch off" mechanism . Unlike traditional clips requiring complex tooling, the Fastclip features a pre-assembled design where all components arrive at site captive on the sleeper, with clips secured in a parked position that does not intrude into the rail seat

Installation & Maintenance Perspective:

Captive Component Architecture: Sleepers arrive on-site with all fastening components pre-assembled and clips held in the parked position, eliminating loose parts that could be lost or misplaced during construction .
Push-Activated Installation: The unique "switch on" mechanism requires simply pushing the clip from parked to installed position, with no threading, bolting, or torque specifications-reducing installation time by up to 75% compared to conventional systems .
Mechanized Equipment Compatibility: Specialized machines like the Rosenqvist Clip Driver CD200 IQ and ROBEL RoClip 34.01 E³ can install Fastclips at rates exceeding six sleepers per minute with a single operator, compared to six workers needed for manual methods .

Maintenance & Operational Perspective

Dual-Piece Insulator Design: The Fastclip separates electrical insulation into two components-one on the side of the rail foot and another on top-enabling independent rail movement in different directions while maintaining electrical isolation for track circuits .
Cast-In Shoulder Integration: Embedded shoulders are cast directly into concrete sleepers during manufacturing, with plastic seal plates preventing slurry leakage during casting and extending mold lifespan by minimizing steel-to-iron contact .
Gauge Adjustment Through Insulators: Rail gauge can be adjusted from -8 mm to +4 mm simply by swapping insulators of different thicknesses, eliminating the need for tie plate movement or shim adjustments .
