    Design of suspended rail reinforcement
    (Wydawnictwa AGH, 2020) Musiał, Tomasz
    The continuous development of coal extraction technology in hard coal mines, including the increased efficiency of the machinery and equipment used in mining, encourages manufacturers to increase the power of these machines. This also entails an increase in their weight. Transporting these machines to their destination, especially to the face, is the task of suspended transport systems, i.e.: a suspended railway system. The proposed solution consists in welding flat bars to the flanges of the I-beam, which will increase the unit weight of the load that can be carried by each car of the transport set moving along the railway. This paper contains a technical description of the modified rail and basic strength calculations, the results of which confirm the advisability of its use.

    Obiekty tunelowe na trasach galicyjskich kolei żelaznych
    (Wydawnictwa AGH, 2009) Preidl, Wojciech
    Misadventures of the Austro-Prussian war showed limited transportation abilities of the existing railroads between Kingdom of Galicia and Lodomeria and the rest of Habsburg-Austrian empire. So was born an idea of extension of the railroads crossing Carpathian mountains on the north-south direction, by connecting them to already existing railroad from Kraków by Przemyśl and Lwów, with the railroads on the Hungarian Kingdom territory. Construction of those railroads, in complicated and challenging terrain, caused necessity of many bridges and tunnels construction. In this paper have shown, on the basis of sources available for the author, story of the construction, localization and current state of many tunnels constructed during those railroads constructing. Talked over the objects placed currently on the territory of Poland as well as the tunnels located an the territory of Slovakia, Hungary, Romania which belonged to the Galicia - province of the former Habsburg-Austrian empire.
