Optimal Maintenance and Renewal Strategy Due to Rail Track Geometry

Francis TITLE : MODELLING RAIL TRACK DETERIORATION AND MAINTENANCE : CURRENT PRACTICES AND FUTURE NEEDS

As commercialisation and privatisation of railway systems reach the political agendas in a number of countries, including Australia, the separation of infrastructure from operating business dictates that track costs need to be shared on an equitable basis. There is also a world-wide trend towards increased pressures on rail track infrastructure through increases in axle loads and train speeds. ...

Strategies for Effective Rail Track Capacity Usage

In the United States, railways are the major means to trans-continentally move goods from ports to the various inland destinations. Due to mergers and abandonment of rail lines, there has been a reduction in the track capacity, concentrating rail traffic to fewer lines. In addition to this, booming trade with Pacific Rim nations has seen the annual trade in the Ports of Los Angeles and Long Bea...

Estimation of track parameters and wheel–rail combined roughness from rail vibration

Rolling noise from railways is significantly affected by the wheel–rail combined roughness and the dynamic properties of the track. To facilitate vibration and noise predictions it is desirable to be able to determine these parameters accurately from field measurements. In this study an inverse method to determine these parameters is adopted and enhanced. Use is made of a track model based on a...
