    Research on the System Safety Management in Urban Railway

    Get PDF
    Nowadays, rail transport has become one of the most widely utilised forms of transport thanks to its high safety level, large capacity, and cost-effectiveness. With the railway network's continuous development, including urban rail transit, one of the major areas of increasing attention and demand is ensuring safety or risk management in operation long-term remains for the whole life cycle by scientific tools, management of railway operation (Martani 2017), specifically in developed and developing countries like Vietnam. The situation in Vietnam demonstrates that the national mainline railway network has been built and operated entirely in a single narrow gauge (1000mm) since the previous century, with very few updates of manual operating technology. This significantly highlights that up to now, the conventional technique for managing the safety operation in general, and collision in particular, of the current Vietnamese railway system, including its subsystems, is only accident statistics which is not a scientific-based tool as the others like risk identify and analyse methods, risk mitigation…, that are already available in many countries. Accident management of Vietnam Railways is limited and responsible for accident statistics analysis to avoid and minimise the harm caused by phenomena that occur only after an accident. Statistical analysis of train accident case studies in Vietnam railway demonstrates that, because hazards and failures that could result in serious system occurrences (accidents and incidents) have not been identified, recorded, and evaluated to conduct safety-driven risk analysis using a well-suited assessment methodology, risk prevention and control cannot be achieved. Not only is it hard to forecast and avoid events, but it may also raise the chance and amount of danger, as well as the severity of the later effects. As a result, Vietnam's railway system has a high number of accidents and failure rates. For example, Vietnam Rail-ways' mainline network accounted for approximately 200 railway accidents in 2018, a 3% increase over the previous year, including 163 collisions between trains and road vehicles/persons, resulting in more than 100 fatalities and more than 150 casualties; 16 accidents, including almost derailments, the signal passed at danger… without fatality or casual-ty, but significant damage to rolling stock and track infrastructure (VR 2021). Focusing and developing a new standardised framework for safety management and availability of railway operation in Vietnam is required in view of the rapid development of rail urban transport in the country in recent years (VmoT 2016; VmoT 2018). UMRT Line HN2A in southwest Hanoi is the country's first elevated light rail transit line, which was completed and officially put into revenue service in November 2021. This greatly highlights that up to the current date, the UMRT Line HN2A is the first and only railway line in Vietnam with operational safety assessment launched for the first time and long-term remains for the whole life cycle. The fact that the UMRT Hanoi has a large capacity, more complicated rolling stock and infrastructure equipment, as well as a modern communica-tion-based train control (CBTC) signalling system and automatic train driving without the need for operator intervention (Lindqvist 2006), are all advantages. Developing a compatible and integrated safety management system (SMS) for adaption to the safety operating requirements of this UMRT is an important major point of concern, and this should be proven. In actuality, the system acceptance and safety certification phase for Metro Line HN2A prolonged up to 2.5 years owing to the identification of difficulties with noncompliance to safety requirements resulting from inadequate SMS documents and risk assessment. These faults and hazards have developed during the manufacturing and execution of the project; it is impossible to go back in time to correct them, and it is also impossible to ignore the project without assuming responsibility for its management. At the time of completion, the HN2A metro line will have required an expenditure of up to $868 million, thus it is vital to create measures to prevent system failure and assure passenger safety. This dissertation has reviewed the methods to solve the aforementioned challenges and presented a solution blueprint to attain the European standard level of system safety in three-phase as in the following: • Phase 1: applicable for lines that are currently in operation, such as Metro Line HN2A. Focused on operational and maintenance procedures, as well as a training plan for railway personnel, in order to enhance human performance. Complete and update the risk assessment framework for Metro Line HN2A. The dissertation's findings are described in these applications. • Phase 2: applicable for lines that are currently in construction and manufacturing, such as Metro Line HN3, Line HN2, HCMC Line 1 and Line 2. Continue refining and enhancing engineering management methods introduced during Phase 1. On the basis of the risk assessment by manufacturers (Line HN3, HCMC Line 2 with European manufacturers) and the risk assessment framework described in Chapter 4, a risk management plan for each line will be developed. Building Accident database for risk assessment research and development. • Phase 3: applicable for lines that are currently in planning. Enhance safety requirements and life-cycle management. Building a proactive Safety Culture step by step for the railway industry. This material is implemented gradually throughout all three phases, beginning with the creation of the concept and concluding with an improvement in the attitude of railway personnel on the HN2A line. In addition to this overview, Chapters 4 through Chapter 9 of the dissertation include particular solutions for Risk assessment, Vehicle and Infrastructure Maintenance methods, Inci-dent Management procedures, and Safety Culture installation. This document focuses on constructing a system safety concept for railway personnel, providing stringent and scientific management practises to assure proper engineering conditions, to manage effectively the metro line system, and ensuring passenger safety in Hanoi's metro operatio

    Towboat on the Ohio

    Get PDF
    To get a personal look at what it is like to work on the Ohio River, newspaperman James E. Casto spent eight days aboard the Blazer as it traveled the Ohio from Huntington, West Virginia, to Pittsburgh, up the Allegheny and the Mongahela, and then back to Huntington. The Paul G. Blazer, a gleaming white towboat owned and operated by Ashland Oil, pushes a group—or “tow,” as the rivermen call it—of nine barges on this trip. Along the way, Casto introduces us to Captain Ronnie Davis, pilot Ronnie Burge, engineer Steve Bellomy, the mates, the deckhands, and the cook, as well as the river itself, the life and the beauty that are the Ohio. Interwoven with the narrative of the trip upriver and back is the history of commerce on the Ohio—of how the flatboats and keelboats gave way to the steamboats and how, in turn, the steamboats were replaced by today’s powerful, diesel-powered boats such as the Blazer. Mark Twain wrote that the Mississippi had a new story to tell every day. The same can be said of the Ohio. As engaging as it is informative, Towboat on the Ohio tells one of the many stories of the busy, hardworking Ohio River. James E. Casto, associate editor of the Huntington Herald-Dispatch, has written articles on the Ohio River for several periodicals. Recounts not just a narrative of [Casto’s] trip but also the colorful history of commerce on the Ohio, along with stories about the communities that grew up along the river and were nurtured by it. —Herald-Dispatch, The Ironton Tribune The leisurely voyage provides an occasion for reflection on the history and current condition of Ohio River navigation, engagingly delivered by a seasoned journalist of the region. James E. Casto was born by the riverside. He writes from a lifetime of observation, and from his heart. —Ken Sullivan, Editor, Goldenseal Our inland waterways and particularly the Ohio River system are crucial to the economic vitality of our region. In our fast-paced modern day lives, with the interstate highway bridges, it is easy to forget the importance of the river. Jim Casto\u27s book recalls our attention to the life of the mighty Ohio in a personal and easy style. His book is a valuable addition to the lore and literature of the Ohio River. —Dan Lacy, Ashland Oil, Inc. Interweaving Ohio River history among his firsthand accounts of towboat travel and life, Towboat on the Ohio kept me turning the pages. —Molly Lightfoot Blom, Editor of HeartLand Boatinghttps://uknowledge.uky.edu/upk_cultural_history/1021/thumbnail.jp
