The diploma thesis deals with the machines used for the maintenance and construction on
railway lines. There are being presented the meaning, scope and methods of maintenance of
the railway infrastructure, including the description and maintenance of the railway track
elements. Examples of maintenance are made in accordance to the slovenian legislation on
the railway substructure and superstructure. In the following thesis a detailed description of
the machinery, which is, based on their functional ability, divided into construction, transport
and trackside equipment is given. Also the vehicle for the different measurements (e.g. rail
measurements – rail profile and rail corrugation, track geometry measurements, track twist
and track cant measurements) are described. In the last part of the diploma thesis is being
shown the technology of the renewal on the section of a single track railway line between the
train stations Škofljica and Ljubljana Rakovnik. The renewal works are divided into six
stages, which include removal of the existing track, excavation of the rails and sleepers,
ballast bed and subsoil, installation of the improved subsoil and frost protective layer and
laying of a new railway track. Besides the technology of the works on the open track section,
with the help of MS Project software, a schedule is being designed, which shows the
duration, order and delay of implementing individual works on the section of the considered
track.
