“…According to Galonske et al, today's European rail freight sector, especially in the area of SWL services, has several challenges (16). These are the high fixed costs linked to infrastructure, poor utilization rates of resources like trains and wagons, and insufficient service quality.…”

One of the major goals of the European Union's transport policy is to increase the market share of rail freight transports. With the Internet, globalization, and just-in-time production, the future of freight transport has moved to high-value and lightweight goods. Rail freight has had difficulty entering this market. Thus, a multipronged strategy is required for improving the rail freight market in which freight is consolidated and transported in Europe by encouraging new players to enter the market. A key pillar of this strategy is the introduction of freight exchanges that are based on principles similar to those of power exchanges. The latter are already well established and operational in the energy sector. This paper describes the market and operational requirements for efficient and reliable freight exchanges in the European freight market from which the rail sector can profit. Lessons learned from the energy sector were reviewed and applied in the context of the rail freight sector in this study. The analysis implies that for rail freight to function, as a pre requisite the freight exchanges would need to provide high liquidity in the market and be neutral to all parties, including shippers and forwarders. Furthermore, to facilitate competition, such exchanges would have to send price signals in the market like power exchanges do. The exchanges would allow automatic bidding, and the transaction process would be efficient and reliable. The rail freight operators would need to provide standardized indistinguishable products to serve as commodities on the freight exchanges.

“…Special attention is given to deviations from decision making processes in marshalling yards. Different types of deviations are presented in [6,15,16] and can be summarised as the following: Deviations of the incoming trainlater (delay) or earlier than timetable plan; Deviations of the outgoing train -later (delay) or earlier than timetable plan; Deviations in personal resources -lack of train driver or other staff for operations in MY; Deviations in individual wagons modification; Unexpected repair or breakage of sections of rail line; Unexpected repair or breakage of wagons; Deviations or incorrect weight of incoming trains or wagons; Priorities in cases of congested infrastructure or other priority policies; Extraordinary requests; Not defined deviations. All deviations can be grouped related to four factors: time, the present state of infrastructure, personal resources, and additional cargo operators' demands.…”

The presented studies, research and innovation focus in marshalling yards is on providing adequate responses on standard timings or deviations from the normal timetable. To address the possible deviations in the marshalling yard daily operation, the decision support system called SMART Real Time Management System (RTMY) is developed and introduced in this study. In general, Smart RTMY should give real-time responses to deviations, and decrease the time for making an adequate decision by providing a decision support system with optimal solutions based on selected criteria and optimization objectives. The system is based on the optimization function, which calculates the numerical (influence) value for each wagon in the marshalling yard, and on the developed expert system. The application of SMART RTMY in its current state is verified through the developed web application used by experts from universities and railways. This system should bring a novel solution to the marshalling yard classification and deviation response systems, thus providing a powerful software tool for marshalling yard dispatchers and operators.

“…For that reason, the cost and operational effectiveness of marshaling yards is of key importance for the revival of conventional rail freight transport. Based on various analyses and railway statistics (see e.g., Boysen et al., ; Galonske et al., ), it can be acknowledged that during the previous decades marshaling yards have not been efficiently used and that their inefficiency has decreased the quality of wagonload service. Generally, a lack of harmony has existed between performed marshaling procedures, designed sidings capacities and realized volume of traffic through the yards.…”

Variable Neighborhood Search for Multistage Train Classification at Strategic Planning Level

Considerations on influences and interrelations between structural design and functional planning are imperative for raising the cost and operational effectiveness of marshaling yards in the context of managing wagonload services. This article focuses on multistage train classification, which rearranges a set of wagons from inbound trains to create a set of multigroup outbound trains in a proper form. Previous papers on the subject of multistage train classification were limited to considerations on the optimal classification schedule addressing the number of sorting steps as a primary objective. In contrast, this article proposes a model for overall optimization of the classification schedule and sidings layout, simultaneously addressing the number of sorting steps and the total number of wagon movements in the objective function. The model is created on a binary integer programming formulation. A Variable Neighborhood Search (VNS) heuristic is developed due to the computational complexity of the problem. Numerical experiments validate the formulated model and demonstrate the efficiency of the VNS meta‐heuristic approach.
