Trams are usually used to carry passengers, but across Europe there are some examples of using them for carrying freight (‘CarGoTram’ of Dresden, Germany and the ‘Cargo-Tram’ of Zurich, Switzerland). There are specific conditions that provide a possibility of using trams for cargo delivery in urban areas. They concern infrastructural, economic, and organisational issues. The main purpose of this article was to identify the conditions and determine the possibilities of implementing a cargo tram in urban areas in Poland. This article has shown that in individual urban transportation systems there are factors that facilitate or inhibit implementation of cargo trams in UFT, and implementation of a concrete solution should be adjusted to the local conditions so that the tram transport system is not disturbed in providing its basic function, i.e. serving the public passenger traffic. To achieve the assumed aim, the following research methods were used: literature review, documentary method, Delphi method, and case study. The area of research was the city of Szczecin, Poland.

This paper focuses on effects of implementing zero-emission buses in public transport fleets in urban areas in the context of electromobility assumptions. It fills the literature gap in the area of research on the impact of the energy mix of a given country on the issues raised in this article. The main purpose of this paper is to identify and analyse economic effects of implementing zero-emission buses in public transport in cities. The research area was the city of Szczecin, Poland. The research study was completed using the following research methods: literature review, document analysis (legal acts and internal documents), case study, ratio analysis, and comparative analysis of selected variants (investment variant and base variant). The conducted research study has shown that economic benefits resulting from implementing zero-emission buses in an urban transport fleet are limited by the current energy mix structure of the given country. An unfavourable energy mix may lead to increased emissions of SO2 and CO2 resulting from operation of this kind of vehicle. Therefore, achieving full effects in the field of electromobility in the given country depends on taking concurrent actions in order to diversify the power generation sources, and in particular on increasing the share of Renewable Energy Sources (RES).

This article has taken up an issue concerning the influence of the implementation of electromobility assumptions on reduction of air pollution in cities in terms of sustainable urban transport systems. The essential nature of the subject is confirmed by the following figures: transport is responsible for almost 25% of greenhouse gas emissions in Europe and is the main cause of air pollution in cities, almost 90% of city dwellers in the EU are exposed to levels of air pollutants deemed harmful by the WHO, and approximately 95% of vehicles on European roads still use fossil fuels. Therefore, the implemented transport policy, both in the international and domestic aspect of particular countries, is facing the need to significantly reduce the negative influence of transport on people and the environment. Electromobility has become one of the concepts that makes it possible to achieve this goal. Its main objective is to reduce emissions of harmful substances into the environment by deploying electric vehicles (EVs). Research conducted by the authors showed that public transport, apart from the obvious effect of decreased number of private vehicles and decreased congestion, can contribute to reduced air pollutant emissions and become a significant driver for the implementation of electromobility in cities. However, the achievement of this goal depends on taking appropriate actions not only in the transport branch but also in other sectors of economy. The following research methods were applied in the article: literature analysis, documentary method, case study, and mathematical methods. The research area was the city of Szczecin, Poland.

The publication presents the results of a scientific work aimed at determining the importance of production processes in different phases of the ship manufacturing system on the effectiveness of means of transport during its through-life. Ship manufacturing is a personalized custom production. Therefore, the future shipowner can precisely planning the technical systems necessary for its future operation. The ship, in the process of production, is prepared for the assumed life cycle, including conditions of its operation and engineering service. Individual approach to ship design and manufactures allows the linking of production processes with the future technical processes of ship servicing and creating the management system including production and using of the means of transport. The issues described in the publication are corresponding to the topic of manufacturing, TES and manufacturing systems.
