RESEARCH METHODOLOGY OF RAILWAY ROUTE DOBOJ – ZENICA, SECTION km 103+500 – MAGLAJ

Abstract

Researched section of the railway route presents a part of the route from Sarajevo to Doboj, built with
two tracks. First track was built in 1947, and the second in 1978. In construction methods are present
differences, considering the time when it was constructed and the way of construction. Both tracks were
used for years for movement of trains of various purposes and speeds up to 100 km/hour. Over time,
the railroad worsened, especially at the beginning of the nineteenth century, when the train speed was
reduced on some sections to less than 40 km/hour. Revitalization of the railway was done by sections
with the task to prepare it for train speed of 120 km/hour.
Evaluation of railway route situation is given based on surveys carried out in the field and
laboratory tests of taken samples. The route was researched rigorously in its corridor, since it has a
movement restriction on its wider area. Regular train lines were maintained which slowed
investigations and some research works could not have been applied. Therefore, were applied
researches that were possible to realize in high quality.
