Trams run easier and safer in Dublin

edilon)(sedra complements the rail fastening system for the new 7.5 km Luas Cross City tram line in Dublin with the supply of high elastic rail joint sealant, Jointelast STP-25. Luas Cross City is one of the largest capital investment projects being undertaken by the Irish government at the moment and will connect the existing red and green lines to make travelling across Dublin city easier and safer.

Following the successful trial installation of STP-25 on Dublin’s Rosie Hackett Bridge (now known as the Marlborough bridge), this rail joint sealant was chosen again for the street running sections of the new tram line.

The 2 component elastomeric STP-25 is used to fill out the void that often is created to accommodate for a certain distance between the railhead and the streets surface. This distance prevents the, wider than the rail, tram wheel hitting asphalt pavement or other kinds of stone like street finish. Wheel (and street) damage is avoided and thus delay of expensive maintenance sequences is achieved.

Another function of STP-25 is sealing of the rail supporting system that is placed around and beneath the rail. By its excellent bonding properties and non-temperature sensitivity it provides for a durable and watertight sealant between the rail and the top surface of the street. Therewith it protects the rail fastening from corrosion or water ingress. The latter might cause electrical insulation problems that must be avoided.

STP-25 is self-levelling and not sensitive to moist. This makes installation very easy where the use of primer can be left out in most cases. Yet another advantage of this fine rail joint sealant product that can be used to improve a wide range of rail fastening systems.

The Luas Cross City tram line is scheduled to start operating before the end of 2017 at which stage the ‘missing link’ in the Luas network will be completed and a new fast and reliable modern transport system will be available.
