Removable insulating chamber for urban railway tracks

THE REMOVABLE INSULATING CHAMBER IS THE IDEAL SOLUTION FOR URBAN LIGHT RAIL TRANSIT SINCE IT SPEEDS UP RAIL REPLACEMENT ACTIVITIES, REDUCES COSTS AND AVOIDS INCONVENIENCES TO RAIL OPERATION AND THE URBAN ENVIRONMENT.

Metrotenerife has developed and patented a removable insulating chamber for rails that solves the inconveniences of the demolition since it can be removed without affecting the track covering. Thanks to its careful geometry, can be easily installed and extracted without any need to remove the covering materials over the track, and it also simplifies the subsequent reinstallation.  In this way, it is possible to reduce time, cost and effort involved in rail maintenance and replacement works, without losing the benefits and robustness of the system.

The components of the removable rail chamber wrap the rail in its lower part and its sides. Thus, meeting the electrical and acoustic insulation needs to prevent the spread of stray currents and the emission of noise to the environment caused by railway traffic.

The innovative solution is compatible with a variety of track surface coverings and rail fastening models. With the removable insulating chamber, the protection cap of the fastening used with the standard encapsulation solutions is no longer needed. In addition, this chamber is also compatible with railroad crossings, where a steel profile is inserted to protect the interface between chamber and coverings.

Moreover, this detachable insulating chamber is environmentally friendly as it is manufactured with recycled materials, eliminates of the use of protective plastic caps and its installation eliminates de production of demolition wastes.

The product is currently installed at Metrotenerife’s track and commercialized by the multinational ArcelorMittal.
