If a railway network is in need of track renewal, it is vitally important that the procedures are carried out to the best possible standards. Network downtime needs to be kept to an absolute minimum and it is therefore essential for infrastructure owners to invest heavily in high-tech track renewal…

With ballasted trackbed here for the foreseeable future, Dr. Nick Thom looks at ways of predicting the rate at which it deteriorates and the factors that affect it.

Rail grinding helps to prevent the dangerous build-up of rolling contact fatigue, and also reduces running noise for line side communities. James Abbott, Technical Editor for Global Railway Review, assesses some developments and significant aspects of this important area of our industry.

One of the most important developments in the last decade was the large scale application of slab track. This is in particular the case for high-speed tracks. In countries like The Netherlands, with very soft soil conditions, classical high-speed tracks could only be realised without massive soil improvements via grouting…

Isolated rail head defects formed under traffic, detected either by visual inspection or ultrasonic flaw testing, can significantly reduce the service life of rails if not managed correctly. Surface initiated defects account for approximately 50% of all defects removed from Network Rail (NR) Infrastructure. These are predominately made up of…

How the modern contacting and contactless inspection and analysis of overhead-line systems on normal and high-speed routes are a guarantee of safe railway operation without disturbances.

For a long time now, poor weld geometry has been a major problem for railway infrastructure. Due to geometrical imperfections, high dynamic loads could be generated during wheel passage. The only way to control the geometrical quality in an effective way, is by measuring and documenting every weld with an…

SBB is minimising the amount of time track is tied up with maintenance, by automating inspection systems and adopting standard components that can be installed rapidly. Global Railway Review’s Technical Editor, James Abbott, talks to Daniel Wyder, SBB’s Head of Asset Management for Track.

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…
28 May 2008 | By Hans-Peter Bartmann, International Sales Manager, Linsinger Maschinenbau GmbH
It was in 2003 when Linsinger Maschinenbau GmbH from Austria launched its new version of the Rail Milling Train SF 03 FFS for German Railways, DB AG, and Alpha-Rail Team for the German Railway Market. Since then, the rail milling technology of Linsinger started a matchless and incomparable victory lap…

Permanent way is required to absorb the static and dynamic forces resulting in vertical (z), lateral (y), and longitudinal (x) directions from railway traffic loads, to effectively distribute them, and to transfer them into the sub-grade at reduced magnitudes. Superimposed on these external forces are additional internal forces arising from…
8 April 2008 | By Dipl.-Ing. Alfred Gruber, Head of Infra Service Division, ÖBB-Infrastruktur Betrieb AG
In order to be competitive on the liberalised rail transport market, the ÖBB Group must operate with market-oriented companies. A key success factor is the reliable transport handling and, thus, the reliability of the infrastructure facilities. That is where the division Infra Service of ÖBB-Infrastruktur Betrieb AG comes in.

Despite modern railways being at the forefront of technologies such as power transmission, signalling, control systems and vehicle dynamics, there is one element which is stuck firmly in the Stone Age – the trackbed. It is true that some tracks are being designed and built with concrete or asphalt bases,…

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…
