Insulating chamber to facilitate and reduce costs of track maintenance

METROTENERIFE HAS DEVELOPED AND PATENTED, FOR URBAN RAILWAY TRACKS WITH EMBEDDED RAIL, AN INSULATING CHAMBER FOR THE RAIL.

Urban railway tracks require electrical and acoustic insulation of the rail to reduce their effects on the urban environment due to the abundance of buildings nearby, pedestrians, piping, etc. This insulation is carried out by means of recycled rubber elements that envelop the rail both on the lower part and on the sides.

When certain maintenance or replacement works on the rail are required it is necessary to remove the above-mentioned insulating element, which makes it obligatory to carry out demolition work on the track coating because it often contains stiff materials (concrete, tiles, asphalt…).

Metrotenerife has developed and patented, for urban railway tracks with embedded rail, an insulating chamber for the rail which fulfils the above-mentioned requirements of insulation. Furthermore, thanks to its careful geometry, can be easily installed and extracted without any need to remove the coating from 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 detachable insulating chamber can be installed on the track with stiff coatings and also on green tracks (grass) as well as on crossroads, for which an additional element has been developed which makes it possible to protect the insulating chamber from the effects of traffic. This detachable insulating chamber has been tested on site under the least favourable conditions, giving highly satisfactory results.
