ERS Systems
PUR Polyurethane Resins
EPUFLEX ST kit including primer materials and two-component polyurethane resins. Designed for continuous or point, permanently elastic rail fastening in track surfaces. It provides very good vibro-acoustic and electrical insulation of the rail, and is particularly effective on sections where reducing the level of vibrations and noise (especially secondary noise) emitted to the surroundings is important.
Product documents
The EPUFLEX ST system can be used in the following types of ballastless track superstructure:
Anchor nodes
Rail fastening system in anchor nodes on point or continuous grouting
EBS System
Embedded Block System – point-based rail fastening system with block supports
ERS System
Embedded Rail System – continuous, elastic rail fastening
Elastic track support
Elastic support of track framework on longitudinal foundation beams – elastic grouting between sleeper and beam
Mixed system
System with continuous rail support and point mechanical fastening
ERS-M Profiles
The modular embedded rail system consists of prefabricated elastomer profiles completely encasing the rail foot, web and partially the head. The system provides continuous, elastic rail support without the need for additional mechanical anchor points. Made of rubber granulate and/or rubber fibers bonded with polyurethane resin, the profiles completely separate the rail from the track structure, ensuring required electrical and vibro-acoustic insulation.
More information
The Embedded Rail System (ERS) provides continuous, elastic rail fastening. The EPUFLEX ST system ensures excellent vibro-acoustic and electrical insulation of the rail, particularly effective on sections where reducing vibration and noise levels emitted to the surrounding area is essential.
