This paper aims to identify and evaluate the bottlenecks and wastes in the loading, unloading, and in-transit processes of iron ore railcars using simulation. A field survey was conducted in one of the largest steel factories and a mine, and each process ...

Learn a subject, for some people, might be an uninteresting and boring activity, especially when the subject to learn are difficult subjects to understand. Many methods used to change learning activities become more enjoyable and interested. This ...

The increase of the utilization of public rail transportations is searched in directions for redistribution of the passenger travels between rail and bus transportation. The rail transport benefits by redistribution of the transportation flows on ...

In railway operations, if the journey of a preceding train is disturbed, the service interval between it and the following trains may fall below the minimum line headway distance. If this occurs, train interactions will happen, which will result in extra ...

This paper describes an algorithm that enables a railway vehicle to determine its position in a track network. The system is based solely on onboard sensors such as a velocity sensor and a Global Navigation Satellite System (GNSS) sensor and does not ...

This paper presents a microscopic model for accurate prediction of train event times based on a timed event graph with dynamic arc weights. The process times in the model are dynamically obtained using processed historical track occupation data, thus ...

Deducing passengers' route choices from smart card data provides public transport operators the opportunity to evaluate and improve their passenger service. Particularly in the case of disruptions, when traditional route choice models may not be valid, ...

Detailed yet computationally efficient simulation models are needed to support the design and operation of modern rail infrastructure systems. LIBROS-II is a model component library for microscopic rail operations simulation. Basic rail elements are ...

Studies have shown that some of the most pervasive sources of noise in our environment today are those associated to transportation. Prediction methods for environmental noise from rail and other sources have been used for more than two decades now in ...

In this paper, we discuss a model to allocate train capacity among multiple travel segments on an Indian Railways train route with several stops. We use a linear programming model and data preprocessing and postprocessing to determine the optimal ...

Aerodynamic efficiency of intermodal freight trains can be significantly improved by minimizing the adjusted gap lengths between adjacent loads. This paper first develops a static model to optimize load placement on a sequence of intermodal trains that ...

This paper summarises the results of using machine vision approach for automating condition monitoring of wooden railway sleepers. Railway sleeper inspections are currently done manually; visual inspection being the most common approach, with some ...

Chinese R&D in intelligent rail transportation systems is evolving rapidly. Key IRTS subsystems include a client service system and a train control and dispatching system. A key national Chinese laboratory is also studying rail traffic control and ...

Train units need regular preventive maintenance. Given the train units that require maintenance in the forthcoming one to three days, the rolling stock schedule must be adjusted so that these urgent units reach the maintenance facility in time. Maróti ...

In the locomotive-scheduling problem (or the locomotive-assignment problem), we must assign a consist (a set of locomotives) to each train in a preplanned train schedule so as to provide each train with sufficient locomotive power to pull the train from ...
