Insulated rail joints: Improving performance at high maintenance track sections

27 February 2019 | By Erik Frohberg, Harald Loy - Getzner, Martin Quirchmair - Getzner Werkstoffe

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

7 September 2018 | By Dong Huiding, Ferdinand Pospischil, Harald Loy - Getzner

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…
