In North America, most rail corridors are constructed using ballasted track. Monitoring the ballast support condition and improving upon current sub-structure/ballast maintenance strategies will ensure safe railroad operations. However, it is inherently difficult to evaluate the pressure distribution at the sleeperballast interface. Researchers at University of Illinois at Urbana-Champaign (UIU...

The casual effect and synergy of high-speed rail development on the modal transport changes in supply chain logistics have not been considered well during initial phase any project design development. This has impaired systems integration connectivity among modes a region. In United Kingdom, High Speed 2, large-scale railway with planned completion date 2033, affects many stakeholders. influenc...

The transformation of the present haulage industry to a more sustainable system is a major challenge and a high priority in the political agenda. In the terrestrial freight market high hopes rely on the intermodal rail-road transport. However, intermodal transport is used for a rather small market segment of concentrated freight flows over long distances. This intermodal transport is based on t...

The SAMGODS group i.e. the four public administration agencies for air, rail, road and maritime transport, SIKA (the Swedish Institute for Transport and Communications Analysis) and VINNOVA (the Swedish Agency for Innovation Systems) is responsible for the commissioning of new models and tools for Swedish analyses of goods transport. A major development initiative is now considered related to t...

In this work, the authors present a detailed train-track interaction model of long freight train operation to predict long-term rail surface damage. addition vehicles and track, intermediate maintenance actions in form cyclic grinding passes have also been modelled according European standards realistically represent evolving wheel-rail interface. The influence longitudinal dynamics inter-vehic...

In 2001, railways in Japan carried 21.79 billion passengers (25.1% of all passenger transport) or 384.5 billion passenger-km (27% of all passenger transport). Rail freight totalled 59 million tonnes (1.0% of all freight transport) or 22.2 billion tonnekm (3.8% of total), clearly indicating that Japanese railway operators are almost exclusively passenger companies. Following the 1987 privatizati...
