“…-Providing an effective maintenance plan: Most of the railway accident by infrastructure failures have occurred from lack of maintenance. As mentioned, attempting to repair outdated infrastructure is a challenge for a civil engineer [24][25][26]. It is because some of the railway infrastructures have been built since 1800s such as London underground.…”

Since the 20 th century, the rail network's growth has been significantly increased worldwide to support passenger demands. One key to success is the safe service from the rail network, which shows a lower number than other public transportations. Nevertheless, many rail authorities have significantly increased safety level and reduced risks for a passenger. The causes of railway accident happened from various factors; however, primary accidents relating to infrastructure failures caused excessive damage to train and people's lives. All failures, which occurred in multi-parts of rail's infrastructure (i.e., roadbed, track, rail bridge), could be the primary causes of train collision and derailment. The overall goal of this study is to analysing uncertainties of railway accidents and, evaluating risk and resilience of rail's infrastructure after occurring an accident. The outcomes are expected to providing safety policies on the railway network. The research precisely conducts long-term global accident data sets, which related to infrastructure failures. The data sets are analysed by using Bayes' and decision tree methods through Python programming. One practical advantage of the study illustrates that the outcomes can apply to the railway networks' safety, reliability, and maintenance policies. Also, the research leads to sustainability surge railway's safety performances from avoiding infrastructure failures problems. As a result, the study reveals that the risk level from infrastructure failures shows at 'high risk' level that scored 18 of 32. Therefore, the research provides a practical recommendation to railway authorities to increase the infrastructure's safety level.

“…As a result, it will decrease CO2 emissions into the atmosphere and increase the capacity of HSR corridors. The replacement of six chief parts of HSRS by CFRP can reduce weight by 24.61% [42]. To reduce energy consumption is essential to reduce the mass per seat, which will reduce the energy lost in braking and increase the size of a car body to accommodate a more significant number of seats [36].…”

The world is becoming more dependent on energy resources, which translates into political dependency on energy-exported states. This will significantly impact the economy, transport, and the environment around the world. Railway transport is becoming an essential mode of transportation because it can operate on an electrified network and has zero carbon emissions. High-Speed Railways (HSR) is an energy-intensive transport system, and it is important economically and environmentally to reduce the amount of used energy. This study examined high-speed rail from an energy efficiency point of view and found factors that can significantly reduce the energy consumption of high-speed rail. This research aims to answer the question that motivated this research: what fundamental factors affect the energy consumption of the selected HSR systems? It estimated the dynamic changes in the total energy consumption for seven HSR systems from 2010-2017 and benchmarked the most energy efficient HSR systems. The non-radial Data Envelopment Analyses methodology has been used to fulfil this research. To conduct complex statistical analyses, IBM SPSS has been applied. The main findings have shown that the decrease in vehicle mass, improved design of high-speed rolling stock and increased occupancy of trains will support the reduction of energy consumption by high-speed railways. The changes in energy consumption strongly correlate with the type of high-speed rolling stock and operational strategies. The expected outcomes of this research will contribute to developing and advancing more sustainable HSR systems. This research will support train operators in making decisions when acquiring new trains and assess the benefits of acceleration in modernising the current rolling stock.
