PRODUCT INFORMATION
The PANDROL DOUBLE RESILIENT BASEPLATEASSEMBLY is typically suited for installation in ballastlessslab tracks and areas where a reduction in groundborne noise and vibration is required. The system suitseither top down or bottom up construction techniques.
The Pandrol e-Clip baseplate is mounted on a studdednatural rubber pad that provides the resilience whichcan be tuned within limits for axle loads and stiffnessrequirements. There is no need to grease or re-tightenthe fastening elements as the rail fastening elementsare non-threaded to provide low maintenance. As withall Pandrol fastenings, the Pandrol resilient baseplatesystem is backed by many years of worldwideexperience, and an unmatched depth of technicalunderstanding from Pandrol’s technical engineers.

PANDROL DOUBLE RESILIENT BASEPLATE ASSEMBLY
FEATURES OF ASSEMBLYAdjustability
Typical lateral adjustment of ±3mm can be
achieved using an eccentric bush, in 1mm
locked steps (additional lateral adjustment can
be provided against specific requirements).
Typical vertical adjustment of up to 20mm can
be achieved using shims.
Maintenance
All resilient parts and wear components are
fully replaceable in-situ. The system has two
independent levels of electrical insulation and
uses Pandrol threadless fastening technology,
providing low maintenance throughout the life
of the system.
Experience
The system has been in use since the mid
1980s and is installed on MRT and LRT
systems in major cities such as Hong Kong,
Singapore, Sao Paulo, Dubai and Istanbul.
It is also installed on main line slab
applications and steel bridges on axle
loads up to 22.5 tonnes.
Installation
PANDROL RESILIENT BASEPLATE
ASSEMBLIES can be installed using either top
down or bottom up construction methods.
Testing
All Pandrol fastenings are tested against
standards published by the Comité Européen
de Normalisation (CEN).

Suitable for all track up to 25 tonne axle loads.
Normally for use on concrete, non-ballasted
tracks. May also be used on concrete sleepers.
Intended for applications where a degree of
vibration attenuation is required.
Application data (standard products – special variants may be supplied for other applications)
Rail inclination Suitable for all rail inclinations.
Clip type Pandrol Brand ‘e’ Clip.
Typical applications At grade, bridges, tunnels and viaducts for metro/LRT and mainline slab tracks.
Typical rail sections 60E1 (UIC60); 56E1 (BS113A); 54E1 (UIC54); BS.80A; AREMA 115RE, S49.
Vertical adjustment Up to 20mm.
Lateral adjustment Typically ±3mm – additional lateral adjustment can be provided against specific requirements
through consultation with Pandrol.
No. of anchors 2 or 4 dependent on track conditions.
Type of anchors Through-bolts (splade or stud type depending on construction method).
Typical performance data
Static stiffness Typically 22.5 kN/mm secant stiffness between 0 and 50 kN on assembly (stiffness can bereduced to 15 kN/mm or increased to >200 kN/mm through consultation with Pandrol).
Mitigation for noise Applicable. Resilient pad is located above and below the baseplate.and vibration after Stiffness can be reduced to ~15kN/mm or increased to >200kN/mm by substitutioninstallation of rail pad and/or baseplate pad.
Electrical resistance >20 kOhms (EN 13146-5:2002) – Two levels of insulation and long leakage pathsuitable for traction return currents in DC systems.
