Over two million containers crossed the docks at Sydney’s Port Botany in 2011/12; a figure that is forecast to increase more than threefold by the end of the next decade. To cope with such large growth in volumes, the New South Wales (NSW) State Government plans to double rail mode share at the port by the year 2020. Conventional wisdom from industry and the media says that existing infrastruct...

The rail fastening system is an important part of a high-speed railway track. It is always critical to the operational safety and comfort of railway vehicles. Therefore, the condition detection of the rail fastening system, looseness or absence, is an important task in railway maintenance. However, the vision-based method cannot identify the severity of rail fastener looseness. In this paper, t...

Recently, the number of studies involving complex network applications in transportation has increased steadily as scholars from various fields analyze traffic networks. Nonetheless, research on rail network growth is relatively rare. This research examines the evolution of the Public Urban Rail Transit Networks of Kuala Lumpur (PURTNoKL) based on complex network theory and covers both the topo...

Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh- Timoshenko beam elements. The rail...

This paper explores the development of rail systems in Ireland and Australia. The paper highlights the different trajectories of both systems and charts the experiences and influences of Empire and Commonwealth on both. In Australia the rail system was developed as a way to promote nation building and overcome isolation while in Ireland both prior to and after partition the system enabled acces...

Railway rolling noise is radiated by the vibration of the rail and wheel. The TWINS model is well established as a method of predicting the generation of vibration and noise and this has been used successfully to design noise mitigation measures. However, the existing model used to predict the sound radiation from the rail considers the rail to be located in free space whereas, in reality, the ...

Genetic diversity of the wild population of the endangered Okinawa Rail, Gallirallus okinawae, was revealed by analyzing haplotypes in the mitochondrial control region for 177 individuals. We found 6 haplotypes with nucleotide differences at 6 sites. The four major haplotypes, Type 1 to Type 4, were present in 121 (68.4%), 21 (11.9%), 8 (4.5%) and 25 individuals (14.1%), respectively. Type 5 an...

The surface of a quenched and tempered spring steel may have decarburized layer from which the carbon component has been reduced. fatigue strength is low compared to base metal, can easily develop cracks. Recently, failure was reported in tension clamp (SKL 15) DFF-300 rail fastening system during use on one urban transit route South Korea. As result measuring depth SKL 15 where occurred, thinn...

Abstract. This paper shows a solution to measure the curvature of a rail-guide in which a robot manipulator moves. Such robot, denominated Roboturb, is destined to welding tasks in rotors of high power hydraulic turbines damaged by cavitation effect. This robot has as mainly characteristics the fact of presenting small load (total mass of 20kg), high mobility level due to its seven degrees of f...
