| Abstract | This paper deals with an operational problem faced by railway traffic controllers. During daily operations, trains need to be scheduled on a bidirectional single-track line with multiple stations to cope with various sources of disturbance that alter the existing timetable. We propose a decision support tool based on a detailed mathematical formulation of the single-line train scheduling problem. State-of-the-art scheduling and rerouting optimization algorithms are adopted to compute good quality solutions in a short computation time. Practical data from RFI, train delays and disrupted tracks are investigated in order to quantify the gap, in terms of delay minimization, between the solutions provided by optimization and by the current FIFO-based dispatching practice. The computational results show that advanced scheduling algorithms are useful when dealing with any kind of disturbed traffic situation, since train ordering decisions have to be taken at each station in both traffic directions. Differently, advanced rerouting algorithms are more suitable when mixed traffic is scheduled, since overtaking between trains travelling in the same direction is only favourable when trains travel at different speeds. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
