Abstract Weather phenomena can result in severe impacts on railway infrastructure. In future, projected changes to the frequency and/or intensity of extreme weather events could change weather–infrastructure risk profiles. Infrastructure owners and operators need manage current put place adequate plans anticipate adapt future risks, or mitigate arising from those risks. The assessment posed infrastructure is dependent a good understanding constituent components risk: hazard , vulnerability...
‘Critical infrastructure’ generally refers to significant pieces of plant and equipment, such as power stations motorways. High population densities in cities, the increasing interconnectedness services supply chains that sustain them, mean local infrastructure is equally important. Local must be able cope with system shocks, whether from natural hazards, terrorism or catastrophic failures. Engineering design plays a major part achieving this, but shocks will occur overwhelm even most...
Currently, no clear standards exist for determining urban building natural ventilation rates, especially under varying realistic meteorological conditions. In this study, rates are determined using tracer gas decay and pressure-based measurements a full-scale (6 m tall) cube. The cube was either isolated (2 months of observations) or sheltered within staggered array (7 months), both single-sided cross (openings 0.4 × 1 m). Wind speeds at height ranged between 0.04 s−1 13.1 s−1. Errors...
This paper examines the application of artificial neural network (ANN) and boosted regression tree (BRT) methods in air quality modelling.

This paper describes the results of experimental work to determine structure slipstream and wake a high speed train. The experiments were carried out using 1/25th scale model four-coach train on moving rig (MMR). Flow velocities measured rake single hot films positioned close side or roof. Tests at different speeds, with without simulation crosswind. Velocity time histories for each configuration obtained from ensemble averages number runs. A small particle imaging velocimetry (PIV) also...
Abstract Extreme high temperatures are associated with increased incidences of rail buckles. Climate change is predicted to alter the temperature profile in United Kingdom extreme becoming an increasingly frequent occurrence. The result that number buckles, and therefore delays, expected per year will increase if track maintained current standard. This paper uses a combination analogue techniques weather generator quantify buckles related delays south‐east Kingdom. concludes by assigning...
Recent experience with the operation of high-speed railways in UK and elsewhere has revealed phenomenon, termed ‘ballast flight’, ballast particles becoming airborne during passage trains, potentially causing damage to both railhead vehicle. This article reports results an investigation into mechanical aerodynamic forces acting on that are generated a train addresses question whether these might offer possible explanation for initiation flight. As trains passed, measurements were made air...

Abstract High temperatures and heat waves can cause numerous problems for railway infrastructure, such as track buckling, sagging of overhead lines, the failure electrical equipment. Without adaptation, these are set to increase in a future warmer climate.

In particular, analysis explored concept harvesting,...
Climate change predictions suggest a trend towards hotter drier summers in the UK. At extreme high temperatures railway network is prone to dangerous, damaging, and expensive rail buckles. In order reduce risk of buckle, emergency speed restrictions are introduced which can be costly. This article presents quantification effects higher summer due climate on UK network. A combination analogue techniques weather generator used establish trends between heat-related delays temperatures. Costs...

Transport infrastructure is critical for societal functioning allowing the movement of goods and services whilst facilitating connections between regions. Additionally, transport varied geographically extensive; it includes roads, railways, associated assets such as embankments, retaining walls railway lines. These are vulnerable in different ways exposed to  hazards with a spatial spread; example, extreme precipitation earthquakes can trigger landslide slope failures mountainous...
