https://doi.org/10.4467/2353737XCT.14.334.3645The article addresses – based on an existing section of a tram line – the evaluation of the capability to substitute an existing train substation (as a civil structure) with several smaller ones. Taking into consideration the real estate prices and the shortage of available plots in the centers of larger cities, the localization of a substation building poses a significant location and budget challenge, when it comes to new tram lines. Additionally, such objects (substations) often spark concern and protests among the tenants of the nearby houses, as they are considered to be the source of a dangerous electromagnetic radiation and, sometimes, noise. The possibility to significantly reduce the size of those objects would mitigate the aforementioned challenges – both environmental and budget-related.

https://doi.org/10.4467/2353737XCT.16.055.5404The existing railway from Kraków to Zakopane is characterised by complex horizontal (curves) and vertical (slopes and rises) profiles. Although the railway is attractive to tourists, it is not highly valued by carriers. This article describes a new route with profile modifications. The new route would be possible mainly due to civil engineering structures such as tunnels. It would make it possible to reduce travel time significantly and reduce energy consumption.
