This book provides an overview and assessment of the security risks, both manmade and natural, facing the railways and rail networks. Railroads face significant threats from disasters, but with situational awareness and coordinated effort these can often be substantially minimized. Transportation assets have always been vulnerable to natural disasters, but in the current environment these assets are also a preferred target of human-caused disruption, especially in the form of terrorism, as the events in many other parts of the world have underscored. Railways are not a homogeneous mode of transportation given their various roles in intercity and commuter passenger movement, as well as being a major portion of the freight ton-miles upon which the U.S. economy is highly dependent. Designed to provide advice for railway owners and first responders, this text discusses how to secure hazardous material transport and how to establish guidelines for rail freight operations and rail passenger operations. The book aims to develop an understanding of the unique operating characteristics of railways, the nature and the range of vulnerabilities, the present means for protecting the infrastructure, and the public policy initiatives that are prerequisite for developing a comprehensive appreciation of the magnitude of this issue. The book utilizes case studies of transport disasters to illustrate lessons learned and to provide critical insight into preventative measures. This book will be of great interest to students and practitioners of transportation, technology and engineering, and security management.

Production and utilization of sustainable energy toward maintaining a clean environment is a major challenge. At the same time, the continued depletion of fossil fuels and the global dependency on non-renewable fuels is a chief concern. Moreover, the long-term economic and environmental issues associated with the high utilization of fossil fuel, such as global warming, are also important, particularly in the context of the predicted increase in the global population to around 5 billion by 2050. In recent years, researchers have been investigating alternative, renewable fuels to replace fossil fuels. Of the various options, biofuels are especially attractive due to their low production costs and the fact that they are pollution free. Also known as transportation fuels, their energy is derived from biological resources or through the biological processes. Biofuels such as biohydrogen, biomethane, biogas, ethanol and butanol offer a number of advantages and can be economically produced from cellulosic biomass. As such, they can play a vital role in sustainably meeting future energy demands. Biofuels have the potential to become a global primary energy source, offering significant reductions in greenhouse gas emissions as well as opportunities to increase economic and social development in rural communities and reduce the problems associated with waste disposal. However, low yields and lack of process technology are some of the aspects that need to be addressed. This book offers an overview of existing biofuels and the technologies to solve the problems associated with their practical implementation. Evaluating the biofuel options and discussing the opportunities and risks in relation to resources, technologies, practices, markets and policy, it provides insights into the development of economically viable bioenergy industries.
