Abstract: The contribution of ballast and subgrade layers behavior to railway track performance is given insufficient consideration in the current railway track models. In particular, stress- and traffic-dependent characteristics ...

Abstract: Considerable parts of worldwide railway networks cross deserts where there are frequent sandstorms, which cause contamination of ballast. One of the most important challenges for railway industries is the adverse effects ...

Abstract: Railway track maintenance management systems are currently based on track geometry indexes with the aim of achieving the required level of track safety. Track passenger ride comfort (PRC) has not been taken into account ...

Abstract: Optimized and cost-effective railway track repair and maintenance planning requires periodic evaluation of railway track performance for which a track condition index is necessary. In particular, rail internal defects have ...

Abstract: This paper develops a new two-dimensional numerical model of vehicle/discontinuous slab track dynamic interaction. The vehicle is simulated as a multibody system with 10 degrees of freedom. The slab track is represented ...

Abstract: Passenger ride comfort (PRC) is one of the most important performance indicators of railway transportation. The current methods for computation and evaluation of railway ride comfort require measurement of train accelerations ...
