ABSTRACT
Traffic on Croatia railroads suffers frequent interruptions due to slope instability occurrence. The case of “Tor” landslide that lies on a tectonically disrupted zone situated on the regional seismically active “Delnice” fault is described. Results of engineering geological, geophysical and geomechanical investigations provided data of the local structure, distribution and composition of soil, so that most probable determinants of the effects that resulted in slope instability could be found. To avoid problems with traffic interruption at this locality it was necessary that the investigations needed to make technical decisions as to remedy actions had to be performed together with the remedy actions itself.
