Problemy Transportu i Logistyki

The article presents the topic of varianting solutions of the concept of metropolitan railway system in the Górnośląsko-ZagłębiowskaMetropolis. Principles of systems engineering have been used in that project, therefore fundamentals of using systems engineering in transportation have been presented. Cases of varianting being allocated in the process of building the concept of MRS (metropolitan railway system) have been presented. A method of varianting at particular stages of building projects of high level and detailed project has been presented as an example of area of varianting. The results of the project are variants of the concept of metropolitan railway system in the area of analysis, for which project of high level and detailed project should be prepared. Concepts which require other project tasks have been also indicated. Varianting of the concept of metropolitan railway system creates conditions for using (in stages) of modern solutions and better exploitation of already existing resources. Results create a possibility of building a modern system of transportation in the Górnośląsko-Zagłębiowska Metropolis, adapted to current and future needs.
