CORRIDOR 10 - a sustainable way of integrations
- choice of construction technology and organization (only during construction in an urban
environment),
- concept of maintaining the railway infrastructure (track micro-geometry).
Introduction of modern railway terminals in the central zones of the city requires minimizing ecological
influences from the railway traffic to the urban environment. The difference between noise emission of
freight car and modern bi-level rail car of Intercity train is about 20 dB(A) (which is same as the
difference between noise from rock concert and from chamber concert. It is therefore necessary to
plan and design railway junctions with a clear separation of passenger and freight transport subsystem
in the area of traffic junction. Figure 3 shows the current reconstruction of the Belgrade railroad
junction, which should enable separation of the passenger and freight transportation, as well as the
relocation of the main passenger rail station.

In the general, the following positions of railway route with respect to terrain are possible: below
ground surface (deep or shallow laid tunnel, cut), on the surface, above the ground (embankment,
bridge). The principle of railway noise transmission to the surrounding objects is shown in Figure 4.
