Abstract [en]

The global trend of urbanization is evident and also valid in Sweden and for the Stockholm-Mälaren region, also referred to as the Mälaren valley, a region consisting of metropolitan Stockholm and areas around the lake of Mälaren. In this context, efficient urban freight transportation has emerged as essential for sustainable development of urban areas. Geographic regions are being expanded due to the fact that rapid transport options have expanded the range of action of people and businesses. Metropolitan regions require freight transports that are often categorized by an inflow of consumables and an outflow of waste and recyclable material. Within urban areas there are ports, terminals and storage facilities that require incoming and outgoing transport. Altogether, these shipments have led to increased congestion on the road network within urban areas, which is a contributing factor to why a shift to intermodal land transports have been advocated both in Europe and in Sweden, thus encouraging more freight to be moved from road to rail. Another contributing factor is the relatively low impact on the environment generated by rail transportation. Efficient use of resources and low emissions of greenhouse gases are factors that are in favor of the train as a transport mode.

Furthermore, conventional rail freight is commonly competitive on long distances and in end-point relations between two nodes. However, an intermodal liner train, as a transport system for freight differs from conventional rail freight transport systems, as it similar to a passenger train makes stops along the route for loading and unloading. Due to the stops made at intermediate stations it enables the coverage of a larger market area. For regional or inter-regional relations, the concept has the potential of reducing drayage by truck to and from intermodal terminals and to make rail freight competitive also over medium and short distances.

The main aim of this thesis project has been to analyze under which conditions a combined transport system with the railway as a base can be implemented in the Stockholm-Mälaren region. Based on a case study for a shipper distributing daily consumables in the region, the feasibility of creating a regional rail freight transport system has been evaluated.

This study provides a methodology for evaluating the feasibility, regarding costs and emissions, of concepts and technologies within freight transportation chains. This has been accomplished by the development of a cost modal, Intermodal Transport Cost Model (ITCM). From the results of the case study one can conclude that a regional rail based intermodal transport system regarding costs is on the threshold of feasibility in the studied region. As for emissions, all evaluated intermodal transport chains contribute to a significant decrease in CO2 emissions compared to unimodal road haulage. The loading space utilization of the train and the transshipment cost are the most critical parameters. The latter restricting the competitiveness of intermodal services to long distances as it is not proportional to transported distance but rather to the utilization rate of resources. Hence, the concept of cost-efficient small scale (CESS) terminals is introduced in this study.

A main prerequisite in order to make the intermodal liner train efficient is a stable and balanced flow of goods with optimized loading space utilization along the route. As the objective is to consolidate small flows, imbalances along the route will constitute an obstacle for the liner train to be competitive. Thus regarding loading space utilization it is necessary to consolidate other freight flows in the train in order to achieve high loading space utilization and a balanced flow along the route. The third parameter which is critical for the results are the fuel prices, where a sensitivity analysis of the results shows that if diesel prices would increase so would the feasibility of the intermodal option. The same is also valid for train length increase as long as the loading space utilization is maintained.

The results of the feasibility study indicate that the evaluated transshipment technologies are closing the gap for intermodal transport to unimodal road haulage regarding transport cost over short- and medium distances and that they contribute to a substantial reduction of CO2 emissions. However, it is essential that also the transport quality is ensured, especially regarding reliability and punctuality. Thus a demonstration project is recommended as these aspects require operational testing. This is particularly crucial regarding novel transshipment technologies.

Abstract [en]

Conventional intermodal rail freight transport systems have proved themselves competitive and able to offer cost-leadership on long distances and in endpoint relations between two nodes. Several studies within intermodal transports have made contributions in finding the minimum distance, the “break-even” distance that an intermodal door-to-door shipment can compete with unimodal road. The results for European conditions are found in the range 300-800 km. The main aim of this doctoral thesis has been to analyse under which conditions a short haul transport system with the railway as a base can be considered a feasible solution.

This has been conducted within the framework of two research projects. In the main research project of this thesis; REGCOMB (Regional Combined Transport System – A system study in the greater Stockholm-Mälaren region), the feasibility is evaluated in a bi-sectional manner; first a quantitative assessment is carried out where costs and CO2 emission are estimated for a set of transport alternatives in the greater Stockholm region, Sweden. The project involves a case study of a shipper’s distribution of daily consumables in the Stockholm-Mälaren region. The case study evaluates the concept of an intermodal liner train, which differs from other conventional rail freight systems, as it similar to a passenger train makes stops along the route for loading and unloading. The quantitative assessment has been accomplished by the development of a cost model, Intermodal Transport Cost Model (ITCM). The most critical parameters are the train’s loading space utilization and the transshipment. The time and cost spent for transshipment of unit loads restrict the competitiveness of intermodal services on shorter distances as these parameters are not proportional to transported distance but rather to the utilization rate of resources. Hence, the concept of cost-efficient small scale (CESS) terminals is introduced and evaluated in this study. Second, a qualitative assessment of the socio-technical system is carried out regarding stakeholders’ perspectives and requirements; based on the participative research i.e. experts involved in in-depth interviews, workshops and a survey. The system must satisfy broader policy objectives of local authorities and commercial corporate interests in order to be adopted. The business model that represents the conceptual idea of the study is identified as ‘the local cooperation model’, where the intermodal transport service is organized by several local actors along a transport route. Regions where cost-leadership coincides with a strong will from local authorities to implement regulations in the freight transport market that promote intermodal transports have created a foundation for implementing short haul intermodal rail freight services. Two operational examples are presented in this thesis; the E&S system in Japan and the Innovatrain system in Switzerland.

In the minor research project of the thesis; BIOSUN (Sustainable Intermodal Supply Systems for Biofuel and Bulk Freight), an evaluation is carried out regarding rail-based multimodal transportation of wood biofuels. In essence, it is the factors affecting rail transportation of biofuel and the inherent capability of the rail mode that are addressed. The qualitative evaluation consists of STEEP analysis for the external factors influencing the transport system and sustainability analysis for the internal factors. These methods are complemented by quantitative analysis of a case study, which offered an opportunity to model a rail-based multimodal transport chain for the supply of a heating plant in Gothenburg, Sweden. The results of the case study show that the break-even distance is considerably lower for biofuel transport chains than for other commodities; 180-250 km, which is mainly due to the requirement of road-road transshipment as well as the fact that intermodal terminals can be combined with wood processing facilities.
