It is a well-known fact that nowadays railway vehicles are designed and manufactured on much higher standard than older vehicles, many of them of obsolete concepts. On the other hand, nowadays railway vehicles designs are more complex and require much higher investment costs. Efforts to minimise costs and demonstrate the economic advantages of these new technologies and designs, throughout the life cycle (LC), launched a process of economic analysis called life-cycle cost analysis and life-cycle profit analysis (LCC and LCP). Life-cycle cost analysis is the process of economic analysis that focuses on the assessment of the total cost of acquisition and ownership, as well as the disposal of a product. This analysis provides important inputs to the decision-making process at the stages of design, development, use and disposal of a product. This paper deals with the analysis of currently the most widely used methods for calculating the costs and profits of the life cycle of a rail vehicle. Example calculation of the costs and profits of life-cycle of a tram with expected 30 years’ service life is presented, too. Following costs for the LCC calculation were used: 0.000 0.010 0.020 0.030 0.040 0.050 0.060 0.070 Profits from passengers Grants from the customer traffic Profits from advertising Euro /seat / km Revenues per kilometer and seat acquisition, preventive maintenance, corrective maintenance, accidents, cleaning, energy, track utilisation, power supply, overheads and salaries. Finally, the individual cost items are discussed.

Nowadays new unconventional intermodal transport units, which are characterized by dimensions larger than standardized ones, are being developed. This should brink higher utility value of such units. On the other hand this leads to many problems which should be solved. The paper also includes some brief information related to the new project TelliBox. Some unconventional methods of manipulation with transport units are mentioned in the paper as well.

Współcześnie rozwijane są konstrukcje nowych niekonwencjonalnych intermodalnych jednostek ładunkowych, które charakteryzują się wymiarami mniejszymi niż standardowe. Powinno to podnieść wartość użytkową tych jednostek. Z drugiej strony prowadzi to do wielu problemów, które należy rozwiązać, Artykuł zawiera także informacje na temat nowego projektu o nazwie Tellibox. W pracy scharakteryzowano także pewne niekonwencjonalne metody prac przeładunkowych związanych z jednostkami ładunkowymi.

Increasing speed of railway passenger transport is a task for all railways. There are two basic possibilities for speed increasing - by new high speed tracks construction with maximum speed over 250 km/h, or by utilization of existing tracks where tilting body vehicles can be operated. Slovakia is not an exception in these efforts. Analysis of theoretically attainable running times on selected ŽSR railway line (Bratislava - Žilina - Košice) by computer simulation program are presented together with discussion on actual situation on already modernized corridor. Parameter areas affecting selection of suitable tilting body railway vehicle and proposed methodology (Balanced Score Card) for determination of optimum parameters of new vehicles for ŽSR are presented. The methodology evaluates the parameters in a balanced way and in mutual relationships.

Wzrost prędkości pociągów pasażerskich jest obecnie zadaniem realizowanym przez większość zarządów kolejowych. Obecnie można mówić o dwóch metodach zwiększenia prędkości pociągów - budowa nowych linii dedykowanych do pociągów dużych prędkości powyżej 250 km/h oraz wykorzystanie istniejących linii na których operują pociągi z wychylnymi pudłami. Słowacja nie stanowi w tym względzie wyjątku. W referacie przedstawiono symulacje komputerowe teoretycznych możliwości pociągów z wychylnymi pudłami na modernizowanej linii Bratysława -Żylina - Koszyce wespół z dyskusją na temat obecnie modernizowanego korytarza. Zaprezentowano nową metodologię optymalizacji parametrów nowych pojazdów szynowych dla kolei słowackich.

Globalization process brought the need for a common understanding of the indicators that are used to measure maintenance and availability performance. There have been numerous systems of indicators developed virtually by each larger company or organisation around the world. However, a common set of indicators and definitions would facilitate the ability of an international company to accurately perform benchmarking between facilities in different counties or continents. To resolve this problem, a team comprised of EFNMS and SMRP representatives is working toward a common set of indicators that can be applied globally. This cooperative effort is termed harmonisation.
