ETCS (European Train Control System) is a unique European standard for controlling and managing a railway traffic. It was a result in a form of need for mutual railway abovestandard in European countries which has a goal to adjust the existing systems of railway managing
and to create a unique European system of insurance which has a result to creat a unique European railway network. Beside the mentioned reasons for introducing the ETCS system other reasons are the increasing diversion of cargo flows from road to rail. To implement the ETCS system on BH railways at Corridor Vc it is necessary to analyse present state of railway infrastructure and to adjust and renew infrastructure so it would be prepared for installation
of ETCS system. In this paper a possibility of introducing of this security on BH railway at Corridor Vc was presented. Implanting of ETCS security system was presented throughout four project options. Project options allude implementation of ETCS separatly for each level
of that system. First project option refers to implementation and modernization of current degree of insurance so that Corridor Vc could be lead to ETCS Level 0. 2nd, 3rd and 4th option is concerning on ability of introducing higher levels of ETCS which are ETCS Level 1, ETCS Level 2 and ETCS Level 3. Whith evaluation of project options analysis it was concluded that each design option is reasonable, cost-effective and profitable.
