Airlines will cancel flights if the weather makes for truly dangerous flight conditions. In most major airlines, pilots have thousands of hours of flying experience and training for flying in a variety of weather conditions, including snow and thunderstorms. 9/26/2022, 1:35:04 AM. In the next seven days, Italy will be hit by at least three disturbances, the first of which is in progress in these hours (ANSA) Due to the situation and the red alert issued by the Civil Protection in Basilicata, rail traffic is now suspended between Potenza and Eboli, on the Battipaglia-Potenza-Metaponto-Taranto line. record of success in bad weather. In the distant past, the railroads spent a lot of money keeping tracks open through snow, but it seems they've cut back today. Fog and bad storms are rough on the airlines and cause bad delays. Fog doesn't hurt trains that much. Storms can, depending on the severity and type of storm, and the ability of the AdkGE8C. During severe weather trains are often busier as people leave the car or bike at home. The rail network copes well with 'run of the mill' winter rail operators plan ahead for bad weather Behind the scenes, rail operators have emergency plans in place to keep that disruption to a minimum. Sometimes trains will be running to a different timetable or under speed restrictions; the aim is to get as many people as possible safely to their destination, even if the journey takes longer than normal. Contact details for many travel operators can be found on our useful contacts page. How train operators deal with severe weather Heated and insulated points, snow clearing trains and crews with chainsaws to remove fallen trees all play a part in keeping the UK's trains moving. You can read more about the types weather that cause the worst delays, and what Network Rail do to minimise these impacts on the Network Rail website. Recent rail disruption incidents Despite that, sometimes the weather can be so bad that disruption is inevitable. In recent years, we've seen storms destroy parts of the railway line at Dawlish in Devon, high winds bringing down overhead lines in the northwest of England stopping electrically powered trains, snow blocking tracks in Scotland and flooding in parts of the West Country. What you can do if you're planning to travel by train In severe weather, you can play a part in helping the people that are trying to get things back to normal as quickly as possible Keep an eye on the weather forecast; would travelling earlier or later make a difference? If there's severe weather happening, national rail enquiries and the train operating companies will issue regular travel updates on their websites. In times of severe disruption, the train companies often relax ticket restrictions but that might mean very busy trains and longer journey times. It's not an option for everybody, but when severe weather is forecast you might want to consider a ticket that allows even greater travel flexibility. Finally, it's easy to forget when you're stuck somewhere you don't want to be, that the disruption is caused by nature, and not the people doing their best to help you. Railway plays an indispensable role in long-distance passenger transport. Here, we investigate train exposure time to bad weather and its influence on an important railway operation problem, train delay. We find that train delay is more likely to occur in snow and rain weather and the total train delay time is in a good correlation with the train exposure time to bad weather. We also develop a train delay network to identify the communities of railway stations from the perspective of train delay co-occurrence. The obtained community structure can be potentially useful in designing regional management strategy for delayed trains.

Ling et al. [8] found that rail delays in China are strongly correlated with extreme weather conditions related to rain and snowfall. Brazil et al. [9] studied the effects of weather conditions on train delays in Dublin, Ireland and concluded that rainfall is the main variable leading to delays, especially when it occurs together with high winds. ...The impacts of adverse weather conditions on railway systems can lead to large delays and cancellations across the entire network. In this paper, we aim to understand the relationship between weather and train disruptions cancellations and large delays across the entire Swedish railway network for the years 2011-2019. Using railway operations data and snow depth, temperature, precipitation, and wind data aggregated on a weekly level, we use visual graphical analysis to understand this relationship. The results indicate that the disruption shares increase with higher amounts of snow and rainfall, and wind speeds. Results show that disruptions increase dramatically both at cold temperatures, with high snow depths, and at high wind speeds. High temperatures and precipitation levels also correlate with increased disruptions, but less dramatically. With projected increases in temperatures and precipitation due to climate change, and an increased frequency of storms, some of these relationships are expected to become more significant, while winter-related problems are likely to decrease. The results highlight the importance of increasing the resiliency of railways to adverse weather conditions and the need for appropriate adaptation strategies.... The Nordland railway line has been assessed in [63], where extreme cold weather is a crucial factor related to delays and low punctuality. Other papers have focused on service delay time and its exposure time to bad weather [64]. A combination of fuzzy theory and rough sets under adverse weather conditions has been used to contribute to the forewarning method for train operation in [65]. ...Eco-driving is a keystone in energy reduction in railways and a fundamental tool to contribute to the Sustainable Development Goals in the transport sector. However, its results in real applications are subject to uncertainties such as climatological factors that are not considered in the train driving optimisation. This paper aims to develop an eco-driving model to design efficient driving commands considering the uncertainty of climatological conditions. This uncertainty in temperature, pressure, and wind is modelled by means of fuzzy numbers, and the optimisation problem is solved using a Genetic Algorithm with fuzzy parameters making use of an accurate railway simulator. It has been applied to a realistic Spanish high-speed railway scenario, proving the importance of considering the uncertainty of climatological parameters to adapt driving commands to them. The results obtained show that the energy savings expected without considering climatological factors account for but if they are considered, savings can rise up to in summer conditions. With the proposed model, a variation in energy of is obtained when summer and winter scenarios are compared while punctuality constraints are fulfiled. In conclusion, the model allows the operator to estimate better energy by obtaining optimised driving adapted to the climate.... For instance, if bad weather is announced snow, storm, preventive measures may be taken. Of course this requires awareness about possible correlations between potential disturbances and related events; see, Ling et al. 2018. ...Network-based systems are at the core of our everyday life. Whether it is electronic networking, electricity grids or transportation, users expect the networks to function properly and provide a feeling of safety and security. However, there may be disturbances. In this paper, we consider disturbances in the context of public transportation. The focus in this respect is on public transport planning and operations. To classify and cope with disturbances, one can find many ideas, including robustness, resilience, vulnerability, disruption mitigation or delay management. We survey related streams of literature and put them into perspective. As a major insight we show that different strands of literature exist that may benefit from becoming better connected and intertwined. Together with recent advances in information technology and solution methods, more integrated problem settings incorporating robustness and disturbances can play a major role in future planning and operations.... multiple dynamic communities, and the stations within the same community follow the similar train operating rules. 4 Train operations are affected by various external factors 3,4,7,9 , such as weather and unexpected events. The bad external environment is easy to cause abnormal operation of the train from different extents. ...High-speed train operation data are reliable and rich resources in data-driven research. However, the data released by railway companies are poorly organized and not comprehensive enough to be applied directly and effectively. A public high-speed railway network dataset suitable for research is still lacking. To support the research in large-scale complex network, complex dynamic system and intelligent transportation, we develop a high-speed railway network dataset, containing the train operation data in different directions from October 8, 2019 to January 27, 2020, the train delay data of the railway stations, the junction stations data, and the mileage data of adjacent stations. In the dataset, weather, temperature, wind power and major holidays are considered as factors affecting train operation. Potential research values of the dataset include but are not limited to complex dynamic system pattern mining, community detection and discovery, and train delay analysis. Besides, the dataset can be used to solve various railway operation and management problems, such as passenger service network improvement, train real-time dispatching and intelligent driving assistance.... Arana et al. [14] found that wind and rain events would lead to a decrease in traffic demand. Ling et al. [15] showed that there was a good correlation between the total train delay time and the train exposure time to adverse weather. Keay and Simmonds [2] also showed that rainfall in winter and spring had the most significant negative impact on traffic volume in Melbourne. ...Extreme rainfall events, such as heavy rainfall and typhoon, can cause unexpected disruptions to the metro ridership and operating system, resulting in severe consequences such as infrastructure malfunctions, service termination and system paralysis. This paper focuses on the spatio-temporal impacts and resilience assessment of extreme rainfall events on metro ridership. The ridership data used in this paper are from the Automatic Fare Collection AFC system in Shenzhen Metro, and the time ranges from May to September in 2017 and 2018 with the 15-minute granularity. This paper not only utilizes big data to analyze the spatio-temporal characteristics of passenger flow under heavy rainfall and typhoon, but also innovatively introduces the meteorological warning signals and ridership resilience curve to analyze the resilience of ridership. The main results reveal that the general heavy rainfall affects passenger flow in the spatio-temporal imbalance. Especially for the spatial aspect, the imbalance of direction and section in peak hours significantly aggravates and the section passenger volume is even larger than usual. For typhoon events, extreme weather can strongly affect the distributions and recovery of metro ridership. Stronger typhoons can have a greater impact on resilience, but continuous rainfall can lead to a longer recovery time. The study results can help metro management agencies better understand the impacts of extreme weather on metro ridership to build a more weather-resilience metro train arrival delay prediction is critical for real-time train dispatching and for the improvement of the transportation service. This study proposes a data-driven method that combines eXtreme Gradient Boosting XGBoost and a Bayesian optimization BO algorithm to predict train arrival delays. First, eleven characteristics that may affect the train arrival time at the next scheduled station are identified as independent variables. Second, an XGBoost prediction model that captures the relation between the train arrival delays and various railway system characteristics is established. Third, the BO algorithm is applied to the hyperparameter optimization of the XGBoost model to improve the prediction accuracy. Subsequently, case studies using data from two high-speed railway HSR lines in China are performed to analyze the prediction efficiency and accuracy of the proposed model for different delay bins and at different stations. The results on two HSR lines demonstrate that the proposed method outperforms other benchmark models regarding the performance metrics of the determination coefficient root-mean-squared error and mean absolute error In addition, the statistical test is carried out using Friedman Test FT and Wilcoxon Signed Rank Test WSRT to validate the efficacy of the proposed method. Furthermore, the train arrival delays at different abnormal events can also be accurately forecasted using the proposed method; the results indicate that the proposed method outperforms other benchmark methods, especially in the prediction of long delays caused by specific abnormal WolniewiczThe article presents issues concerning rail transport rail, metro and tramway and factors influencing the planned implementation of the schedule. At the beginning, the scope of application of the robustness concept was analysed, based on scientific and industry literature. Then the attention was focused on the model of the rail transport system and the schedule, the basic indicator of robustness assessment was discussed, taking into account the methods of analysis used and many variables occurring in rail transport. Finally, a review of the state of knowledge is summarised and the most important observations from the analysis are indicated. In the case of a robust schedule there is no propagation of disruption across the network after an adverse event has has not been able to resolve any references for this publication.
