Insulated rail joints: Improving performance at high maintenance track sections

27 February 2019 | By , ,

Signalling systems are part of every modern rail network. These systems create a safe and efficient operation by employing the rail as an electrical conduit for train location. To accomplish this, insulated rail joints (IRJs) are used to create blocks or independent sections of track by electrical isolation. Shortened IRJ…

Bedding optimisation in turnouts

26 November 2007 | By Harald Loy, System Engineer, Getzner Werkstoffe GmbH

Geometrical discontinuities along turnouts can lead to strong localised variations of superstructure loads. By using Under Sleeper Pads (USP) with varying stiffness, the bedding conditions can be optimised and as a result the turnout area can be smoothed out. Modern railway tracks need to be able to bear the loads…
