THE TERAIN CHARACTERISTICS OF RAILWAY ALONG THE ENTITY BORDER OF FEDERATION BIH - MAGLAJ, SECTION km 103+500 - MAGLAJ

Abstract

The railway Samac - Sarajevo was built in the fifties of the twentieth century, as a significant part of
the railway that connects the central part of the former Yugoslavia with the Sava River. Later, in the
seventies another track of Doboj and Zenica was built what was the most important by that time. In
general the railway is situated on the corridor V, which links the Adriatic Sea via Sarajevo and Budapest.
Over time, the tracks are worn, damaged and speed has been reduced to about 40 km/hour.
As part of the revitalization of the railway network in the former Yugoslavia, the reconstruction of the
Samac - Adriatic Sea began, which is divided by sections. One of these sectionsis the section km 103
+ 500 - Maglaj, a more demanding one compared to previous section from Samac to the now named
section. The point is that the terrain along the route of the railway needs to be viewed from the aspect
of geologi cal features, then the characteristics of the embankment so the geotechnical conditions for
the revitalization of the railway line for speeds of 120 km/hour can be provided.
Conducted field investigations along the route of the railway, as well as laboratory tests on samples
provided enough data in the corridor route, while the wider area could not be perceived because of the
mine field. However, the previous studies for the purposes of the General Geological Map, scale 1:
100 000, and field observations along the route line gave a satisfactory level of data for assessment of
geological and engineering geological characteristics of the terrain.
