3rd International Scientific and Professional Conference CORRIDOR <strong>10</strong> - a sustainable way of integrations Fig. 1 The harmonization procedure for technical regulations for railway infrastructure maintenance in the Republic of Serbia [9] This paper analyses European technical regulations in the area of railway track maintenance, shows the current level of harmonization of Serbian regulations with EU technical regulations and gives directions for solving this task. 2. TECHNICAL REGULATIONS IN THE AREA OF RAILWAY TRACK MAINTENANCE IN EU 2.1. Technical Specification of Interoperability and the conventional railway system maintenance The Technical Specification of Interoperability relating to the trans-European conventional rail system - Subsystem Infrastructure covers the conventional railway system maintenance from the aspect of safety, reliability and availability, health, environmental protection and technical compatibility of the maintenance installations for conventional rolling stock [6]. The technical installations and the procedures used during the maintenance must ensure the safe operation of the infrastructure subsystem and not constitute a danger to health and safety. Also, the influence of the technical installations and the procedures must not exceed the permissible levels of nuisance with regard to the surrounding environment. According to [6] the Infrastructure Manager has to define, for each conventional rail line, a maintenance plan. The plan defines types of inspection and testing and their frequency, professional competences of staff, measuring methods and necessary procedures. Therefore the maintenance plan shall contain at least [6]: • a set of limit values, • a statement about the methods, professional competences of staff and personal protective safety equipment necessary to be used, • the rules to be applied for the protection of people working on or near the track, • the means used to check the respect of in-service values, and • the measures taken (speed restriction, repair time) when prescribed values are exceeded.

3rd International Scientific and Professional Conference CORRIDOR <strong>10</strong> - a sustainable way of integrations Maintenance plan is related to the following elements: • requirements for equivalent conicity in service, • in service geometry of switches and crossings, • track geometric quality and limits on isolated defects, • platform edge as required by the "People with reduced mobility" TSI, • inspection of tunnels condition as required by the "Safety in Railway Tunnels" TSI, and • professional competences for maintenance staff. Figure 2 shows the concept development for creation of the maintenance plan. Fig. 2 Concept development for creation of the maintenance plan The basis for creation of the maintenance plan is measurement data from the railway network. In that way, the data collected from the network using track recording vehicles gain great importance. During measurements, exceeding of the regulated limit values is registered and if necessary appropriate measures for traffic safety insurance can be taken. After the recording run, quality data with further instructions regarding registered defects are uploaded on the intranet network and become available to all the operators. 2.2. European standards concerning track geometry quality European Committee for Standardization (CEN) has created a group of standards EN 13848 "Railway applications – Track – Track geometry quality" which consists of six parts. The sixth part of this standard is currently under development and the draft has been submitted to CEN members for voting [12]. The objective of creation of this group of standards is defining a unique approach for the evaluation of track geometry quality of various European railway infrastructures. This group of standards is a basis for creation of the railway infrastructure maintenance plan. The first part of this European standard "Characterisation of track geometry" specifies the requirements for the homologation of track geometry quality as measured by various measuring devices fitted on track recording vehicles [1]. It defines each parameter and specifies the requirements for measurement, the analysis method and the presentation of results. The part 2 "Measuring systems - Track recording vehicles" defines the specification for measurement Belgrade, 2012 52
