Insulated Rail Joint

Next generation high performance insulated rail joint

No more mechanical failures. Double the lifespan. Withstand high frequency train operations. 
Equipped with cold hole expansion and an insulated and waterproof coating. These are just a few of the functional requirements from the performance contract with the Dutch Rail infrastructure manager. The NRG joint has been used for years now without any problems.

The vulnerability of IRJs to wear and tear has for many years been one of the major causes of malfunction of the railway infrastructure. This is why our new IRJ had to comply with a huge number of requirements. These issues have been successfully tackled, which has resulted in an high-performance product. A completely refurbished design and the development of various new elements have resulted in a model with a remarkable lifespan. The NRG joint has been successfully applied in the Netherlands, Belgium and the United Kingdom.

The new glued Insulated Rail Joint is able to absorb the wave motions of the rail ensuing from the driving dynamics of the train. It moves, so to speak, in the same way as the rail, a property which has formed the basis for our new product’s name: eNeRGy joint (NRG).

Impressive test results
The high quality of the NRG joint is convincingly demonstrated by the results of multiple extensive tests, known to be the toughest in the world. An unprecedented amount of bending and tensile tests has shown that our NRG joints can be exposed to extreme forces for prolonged periods of time.

Key benefits:

»  Highest withstand of deflections without any damage (> 16 million deflection with 3 mm)

»  No hazard from micro cracking in holes due to cold hole expansion

»  The adoption of the NRG significantly decreases the tracks’ life cycle costs (LCCs)

»  The NRG joint has been designed as a single model that can be used on all major track structures

»  Coating is waterproof and resistant of UV, road salt, and sea water (least corrosion)

»  Coating prevents sticking of iron grinding chips and splinters (no installation of magnets  

»  The NRG joint is designed to fit within the space envelope specified for mechanical tamping &
    grinding/milling machines

»  Sleeper distance from 300/600/750mm

The NRG joint is the newest generation of a bonded insulated rail joint, that is pre-assembled at the factory in Hilversum (the Netherlands) in climate controlled conditions.

Repair System Insulated Rail Joints

In case you have issues with your insulated rail joint NOW, we offer the following solution: the Repair System, applicable for all joints.

Insulated rail joints have been found to be a cause of malfunctions in the rail infrastructure. Internal research has also shown that all of the installed insulated rail joints require maintenance to retain optimal quality.

voestalpine Track Solutions Netherlands B.V. has responded to this problem which the maintenance market has been facing. We have been developing products for the repair of damage to all types of insulated rail joints, quickly and cost-effectively. Defects are often caused by a lipping, partly missing or damaged end post. The end post is the plastic isolation or profile plate between the rails. Essential for the well-functioning of the insulated rail joint.

The repair system for insulated rail joints is a quick and easy way to repair glued insulated rail joints and expand their service life. A fully repair can be done within 20 minutes in a few simple steps. A detailed work instruction is provided along with a very handy case.
