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…

Heavy-haul in China: Investigating durable elasticity for superstructure

Ballast is the weakest link in rail superstructure. However, by…

Ballast is the weakest link in rail superstructure. However, by mounting Under Sleeper Pads (USPs), ballast tamping requirements can be reduced and the availability of the track can be significantly increased. Here, Getzner colleagues, Dong Huiding, Ferdinand Pospischil and Harald Loy compare elastic and non-elastic track components, with details of…

Measuring the vibration-isolating effect of an elastic railway superstructure in Poland

13 February 2018 | By , ,

The Railway Institute at Wrocław University of Science and Technology has convincingly demonstrated the value of the cost-effective type SLS1308G under sleeper pads used on the Kraków Airport rail link in Poland. Here, Ewelina Kwiatkowska, Adjunct Professor at Wrocław University of Technology, together with Getzner Werkstoff colleagues Harald Loy (Head…

Under Sleeper Pads: improving track quality while reducing operational costs

More traffic, increasing axle loads and higher speeds are just…

1 August 2008 | By Harald Loy, System Engineer, Getzner Werkstoffe GmbH

More traffic, increasing axle loads and higher speeds are just some of the ongoing technical and economic challenges railway operators and track managers around the world are faced with today. Under Sleeper Pads (USP) have been proven to extend the service life of the track superstructure and help to reduce…

Bedding optimisation in turnouts

Geometrical discontinuities along turnouts can lead to strong localised variations…

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…
