Railway switch and crossing (S&C) systems have a very complex structure that requires not
only a large number of components (such as rails, check rails, switches, crossings, turnout …

The unavoidable increase in train speed and load, as well as the aging of railway facilities,
is requiring more and more attention to rail defects detection. As a promising tool for rail, in …

The vehicle scanning method (VSM), an indirect approach for bridge measurement, has
attracted intensive attention since it was proposed. By this method, a moving test vehicle is …

In this paper, a novel railway track monitoring approach is proposed that employs
acceleration responses measured on an in-service train to detect the loss of stiffness in the …

The modeling of dynamic frictional rolling contact is crucial for accurately predicting behavior
and deterioration of structures under dynamic interactions such as wheel/rail, tire/road …

Railway turnouts are essential in the train traffic route management for modern railways.
Despite significant devotion to railway turnout research, one of their most common failures …

The ballasted track superstructure is characterized by a relative quick deterioration of track
geometry due to ballast settlements and the accumulation of sleeper voids. The track zones …

Fault diagnosis plays a major role in railway condition monitoring, as early diagnosis of the
emerging faults can save valuable time, reduce maintenance costs and, most significantly …

Various techniques have been developed to detect railway defects. One of the popular
techniques is machine learning. This unprecedented study applies deep learning, which is a …

The increase in demand for railway transportation results in a significant need for higher
train axle load and faster speed. Weak and sensitive trackforms such as railway switches …
