The system performance reduction and the corresponding increase of transit time are often due to the increase of the freight flow without a corresponding increase of stacking and handling capacity. For this purpose it was decided to approach the problem by a discrete event simulation model, in order to reproduce the activities carried out inside an intermodal terminal, to calculate the total transit time and to identify the bottlenecks. The transit time of a cargo unit in a terminal is the summation of times required for the development of each phase of the process (waiting time + operational time). Therefore, the first step was the identification of the main activities and the analysis of waiting and operational phases, in order to quantify the times of each phase. For modelling the software Planima...

The European Commission is working towards the creation of a Single European Railway Area, encouraging a modal shift towards rail (mainly from road) in order to achieve a more competitive and sustainable European transport system. In this context, the research sector is contributing to the competitiveness and attractiveness of rail transport by tackling issues such as reliability and quality of services. Many parts of existing railway infrastructure are operated almost at full capacity and are not always capable of offering adequate levels of service. There is thus the need to boost the productivity of infrastructure assets in order to improve the reliability and responsiveness to customer requirements, as well as the capacity and the whole efficiency of rail transportation. This article provides a review and a practical comparison of capacity and punctuality assessment methodologies. Most importantly, it also identifies and evaluates a manageable and streamlined approach to their estimation for preliminary or large scale analysis based on consolidated formulations for travel time, delay and utilized capacity. This becomes particularly relevant in the absence of detailed infrastructure and timetable data as we aim at evaluating some fundamental operational and performance indicators.
The use of Petri nets models in railway traffic applications

All the developed models are based on working criteria and operational rules of interlocking and line signaling systems. The modeling is based on a strongly modular object oriented approach capable to usefully simulate the process with all boundary conditions imposed by infrastructure, signaling and control systems.

The intensive programme employs an innovative multidisciplinary approach that combines a number of learning methods, such as: Lectures; Project-based learning; and Technical Visits as well as Thematic Seminars. We will work with approximately fifty undergraduate students and twenty professors in railway, transport and logistics from different locations from Europe. The targeted learning outcomes are to develop the undergraduate student's ability to initiate and carry out analysis, research, seminars and workshops with the purpose of solving railway and logistics-related problems.

The three classic management levels for rail planning, i.e., strategic, tactical and operational, are introduced followed by decision support systems for rail traffic control. In addition, included in this paper are discussions on train operating forms, railway traffic control and train dispatching problems, rail yard technical schemes and performance of terminals, as well as timetable design. A description of analytical methods, simulation techniques and specific computer packages for analysing and evaluating the behaviour of rail systems and networks is also provided.

The concepts and the usual practice for rail wagon design, both freight and passengers are presented. A discussion on rail and the environment comes next followed by Truck-Trains. Accident theories, metaphors and investigation methods are widely discussed; Hazard – Barrier – Target Model, Swiss Cheese Model, Bow-Tie Model, Fault Tree Analysis and Event Tree Analysis are explained. This paper concludes with a technical discussion on safety and security of rail vehicles, standards for safety and measures against terrorist attacks.

More specifically the study presented consists of two surveys, as follows. The first survey, Supply Survey, explores existing transport and logistics-related courses and educational programmes offered in higher education institutions. The second survey, Demand Survey, examines demands for rail logistics higher education and aims to understand the current needs for higher education in the sector. This paper shows that a spectrum of rail, freight transport and logistics related courses and programmes exist, however there is a strong need for a more specific training and education offering operations management skills needed to improve the company performance, efficiency and quality of service provided.
