This thesis addresses the problem of constructing train schedules, in particular for large and highly utilised railway networks. In the thesis, a comprehensive approach from the commercial description of intended train services to a conflict-free detailed schedule for a whole day is developed. The methodology follows a divide-and-conquer strategy based on three description levels: the service intention, the macroscopic timetable, and the microscopic schedule. The levels are interfaced in such a way that planners have the possibility of intervening into the specifications on every level, and enabling a feedback loops for testing different alternative scenarios.The starting point of the approach is the construction of an appropriate structure for describing the intended train services, including periodicity information. This partial periodic Service Intention (ppSI) contains the commercial offer that a railway company would like to tender to the customers during a day. The developed ppSI can describe commercial railway offers with partial periodic structure in a compact form and can exploit these effectively in the train scheduling process. This is done with an equivalent projection onto a single period time, resulting in an augmented periodic problem. ThlS augmented periodic timetabling problem is then solved first 9lobally on an aggregated topology with a simplified safety model (macroscoplC level), and subsequently, locally refined by considering more details of the railway infrastructure and train dynamics (microscopic level). Finally, the generated periodic conflict-free train schedule is rolled out over the complete day to create a conflict-free production plan.The macroscopic level focuses on global interdependencies over the entire network for generating the most important properties of the timetable. A well known model for this description level is the periodic Event scheduling problem (PESP). In this thesis, an extension called Flexible Periodic Event scheduling problem (FPESP) is introduced and applied, allowing for time slots for each event instead of fixed times. Moreover, an extension of the FPESP model is proposed, the Flexbox model, which is a further generalisation of the FPESP that allows to make use of natural dependencies among events in the service intention.
This book presents the latest findings on train operation theories and methods in the context of emergencies. It examines and assesses a range of aspects—including the definition of a railway emergency, transport organization modes in emergencies, calculating railway transport capacity in emergencies, line planning in emergencies, train re-pathing in emergencies and train re-scheduling in emergencies—that are urgently needed in the railway transportation field, which faces the serious challenge of dealing with emergencies worldwide. The book highlights the latest research results in an integrated and systematic way, and the methodology presented is oriented on real-world problems, allowing it to be used not only directly in railway operational management, but also as the point of departure for further applications or theoretical research. As such, the book will be of considerable interest to graduate students and researchers in the field of traffic and transportation engineering.>
The Tea and Sugar Train (also known as Slow Mixed Goods Train No. 5205) was a specific train that provided service to isolated Australian towns on the Nullarbor Plain between Kalgoorlie and Port Augusta along the Trans-Australian Railway. This train was significant because in its early years of service provided all the supplies used by remote towns in South and Western Australia. The Tea and Sugar Train began in 1917 as a supply train for workers constructing the Trans-Australian Railway. Railway workers depended on the train for every necessity as the rail link was the main form of regular transport into the region. The train travelled along the world's longest stretch of straight track, which is straight for 478 kilometres (297 mi).
