Railway ballast beds bear cyclic loadings from vehicles and deteriorate due to ballast
particle degradation (breakage and abrasion), ballast pockets (subgrade defects), fouling (or …

Increased demand for railway transportation is creating a need for higher train speeds and
axle loads. These, in turn, increase the likelihood of track degradation and failures …

Railway transportation systems are important for society and have many challenging and
important planning problems. Train services as well as maintenance of a railway network …

Since multiple failure events associated with derailments could not be identified and
derailment probability could not be reached quantitatively by event tree and fault tree …

The volume of rail traffic was increased by 5% from 2006 to 2010, in Sweden, due to
increased goods and passenger traffic. This increased traffic, in turn, has led to a more rapid …

We develop a multi-level decision making approach for optimal condition-based
maintenance planning of a railway network divided into a large number of sections with …

In the past few decades, the railway infrastructure has been widely expanded in urban and
rural areas, making it the most complex matrix of rail transport networks. Safe and …

In the past few decades, high-speed trains have witnessed tremendous and vigorous
development with the appearance of the oil crisis and industrialization, which became a …

Ballast plays an important role in the stability of railway track systems. The effectiveness of
the ballast in maintaining the track stability is very much dependent on its mechanical …
