rail operations from infrastructure ownership and management, the government-owned national railways still maintain a symbiotic relationship with infrastructure providers. New entrants to rail business face considerable hurdles in terms of access to infrastructure and operations at border crossings. Moreover, passenger traffic has precedence over freight traffic. Thus, train timetables are crea...

The growth of fatigue cracks in rail is a cause of ongoing concern to the railway industry, and much research and development work has been conducted to develop both trackside and train mounted analysis systems which are able to monitor the structural health of railway networks. To this end a new infrared-based method for surface crack quantification at conventional train speeds is being develo...

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-&#10Timoshenko beam elements. The ra...

We investigate the integration of scheduling for a rail system and some of the operations in a coal terminal system, based on representative data. The rail and terminal systems are tightly-coupled and experience a high service demand from the expensive infrastructure. This makes efficient operations essential. However no central authority is in a position to effectively create global schedules ...

9 To provide stable and high data rate wireless access for passengers in the train, it is necessary to 10 properly deploy base stations along the railway. We consider this issue from the perspective of service, 11 which is defined as the integral of the time-varying instantaneous channel capacity. With large-scale 12 fading assumption, it will be shown that the total service of each base statio...

22 23 Implementation of highway-rail grade crossing warning systems, educational programs and 24 research on crossings have all contributed to a steady reduction in the risk to highway users of 25 grade crossings over the past several decades. Much less attention has been given to 26 understanding the effect of grade crossings on train safety and risk. Collisions at highway-rail 27 grade crossi...

Understanding the nature of rail transit dwell time has potential benefits for both the users and the operators. Crowded passenger trains cause longer dwell times and may prevent some passengers from boarding the first available train that arrives. Actual dwell time and the process of passenger alighting and boarding are interdependent through the sequence of train stops and propagated delays. ...

The paper explains a new advanced rail traffic management system that combines real-time rescheduling with an advanced train control tool being developed by the Swiss Federal Railways (SBB) in cooperation with the Swiss Federal Institute of Technology (ETH). The system is designed to increase network capacity and stability in heavily used mixed traffic networks while minimizing the cost of new ...

In modern rail-rail transshipment yards huge gantry cranes spanning all railway tracks allow for an e cient transshipment of containers between di erent freight trains. This way, multiple trains loaded with cargo for varying destinations can be consolidated to a reduced number of homogeneous trains, which is an essential requirement of hub-and-spoke railway systems. An important problem during ...
