Book Description
This book focuses on the latest scientific and technological advancements in the field of railway turnout engineering. It offers a holistic approach to the scientific investigation of the factors and mechanisms determining performance degradation of railway switches and crossings (S&Cs), and the consequent development of condition monitoring systems that will enable infrastructure managers to transition towards the implementation of predictive maintenance. The book is divided into three distinct parts. Part I discusses the modelling of railway infrastructure, including switch and crossing systems, while Part II focuses on metallurgical characterization. This includes the microstructure of in-field loaded railway steel and an analysis of rail screw failures. In turn, the third and final part discusses condition monitoring and asset management. Given its scope, the book is of interest to both academics and industrial practitioners, helping them learn about the various challenges characterizing this engineering domain and the latest solutions to properly address them.

Book Description
The American public has a fascination with railroad wrecks that goes back a long way. One hundred years ago, staged railroad accidents were popular events. At the Iowa State fair in 1896, 89,000 people paid $20 each, at current prices, to see two trains, throttles wide open, collide with each other. "Head-on Joe" Connolly made a business out of "cornfield meets" holding seventy-three events in thirty-six years. Picture books of train wrecks do good business presumably because a train wreck can guarantee a spectacular destruction of property without the messy loss of life associated with aircraft accidents. A "train wreck" has also entered the popular vocabulary in a most unusual way. When political manoeuvering leads to failure to pass the federal budget, and a shutdown is likely of government services, this is widely called a "train wreck. " In business and team sports, bumbling and lack of coordination leading to a spectacular and public failure to perform is also called "causing a train wreck. " A person or organization who is disorganized may be labelled a "train wreck. " It is therefore not surprising that the public perception of the safety of railroads centers on images of twisted metal and burning tank cars, and a general feeling that these events occur quite often. After a series of railroad accidents, such as occurred in the winter of 1996 or the summer of 1997, there are inevitable calls that government "should do something.

Book Description
A railway is a complex distributed engineering system: the construction of a new railway or the modernisation of a existing one requires a deep understanding of the constitutive components and their interaction, inside the system itself and towards the outside world. The former covers the various subsystems (featuring a complex mix of high power sources, sensitive safety critical systems, intentional transmitters, etc.) and their interaction, including the specific functions and their relevance to safety. The latter represents all the additional possible external victims and sources of electromagnetic interaction. EMC thus starts from a comprehension of the emissions and immunity characteristics and the interactions between sources and victims, with a strong relationship to electromagnetics and to system modeling. On the other hand, the said functions are achieved and preserved and their relevance for safety is adequately handled, if the related requirements are well posed and managed throughout the process from the beginning. The link is represented by standards and their correct application, as a support to analysis, testing and demonstration.

Book Description
This thesis can be divided into two parts. In Part I we are dealing with the problem of finding optimal time intervals for carrying out routine maintenance works and large projects in such a way that the track possession costs and maintenance costs are minimized. In Part II of this thesis we focus on rescheduling of the rolling stock in the passenger railways due to changing circumstances and more precisely on the Rolling Stock Rebalancing Problem (RSRP). The main objectives of this thesis are formulated as follows: 1. Review the existing literature on maintenance planning in relation with production. 2. Identify some tactical and operational railway infrastructure maintenance planning problems and develop operations research models for providing decision support. Investigate the effect of planning railway infrastructure maintenance on the train operation and identify rolling stock planning problems that occur during planned infrastructure maintenance. 3. Analyze the considered models, investigate their computational complexity, propose solution methods and test the solutions of the models.
