COVERING ALL SEGMENTS FROM DESIGN TO MACHINE COMMISSIONING WHICH ALLOWS CONTRACTING WORK BASED ON “TURNKEY” SYSTEM

Five decades of experience in the cabling, installation, activation, testing and commissioning of railway signaling and safety (SS) and telecommunication (TC) devices.

We laid thousands of kilometers of power cables, signaling and telecommunications cables, we installed and put into operation hundreds of devices to secure the rail – road crossings (level crossings).

We install mainly modern electronic devices whose security is based on the parallel operation of two computers.


BF POSIT Ltd. is an independent economic entity (as a daughter company of the Croatian Railways) which existed from the beginning of 2002 till 01.03.2013., when it became part of the company Pružne građevine Ltd. It was found on the basis of the production unit for the construction of electrical apparatuses, operating in the system of the Croatian Railways. The company has half a century of experience in the cabling, installation, activation, testing and commissioning of railway signaling and safety (SS) and telecommunication (TC) devices. We laid thousands of kilometers of power cables, signaling and telecommunications cables, we installed and put into operation hundreds of devices to secure the rail – road crossings (level crossings). Before, in general, there were relay devices, in the last ten years we mostly install modern electronic devices, whose security is based on parallel operation of two computers.

We also installed dozens of the station relay SS devices on almost all corridors and railway lines in Croatia, which includes devices for the Automatic Train Protection (ATP) on trunk lines.

In addition to engineering and installation department, which works are mainly carried out on a site, BF POSIT has a productive part in it’s program in which we make various parts of SS devices: signals, distant signals, maneuvering and limit signals, semi-barriers setters, telephone and cable cabinets and all kinds of warning labels. We also repair worn-out securing elements and provide support for external field crews (galvanized metal cable sheets, concrete foundations for signals, various frames, girders and the like).

Besides the installation of new devices, a significant portion of the company’s external work is investment maintenance and monitoring work on all rail repairs (disassembly and reassembly of the securing elements, replacement of worn-out elements, cable route protection, and if necessary, turn off and turn on of SS units).

From railway machinery, the most important are 10 TMD vehicles (three with platform and seven with crane), and a large number of wagons, to accommodate workers, wagons for warehouses, workshops and tanks. In the last ten years we invested a lot of our resources to improve working conditions and stay on a site, and procured some 10 refurbished wagons with central heating and air conditioning.

In addition to work on the installation of devices that the company does for several decades, a technical office has been organized which currently employs three authorized Electrical and Electronics Engineers, members of the Croatian Architects and Civil Engineers Chamber. With the production of project documentation, we raised the quality of test documentation and as-built documentation during the installation. In this way BF POSIT covers virtually all aspects from design to machine commissioning, which, with the great labor mobility, allows us to contract work on “turnkey” system.

The total number of employees in BF POSIT is 348 (on 06.02.), Which is twice more than in 2002, from which an increase in the volume of work can be seen. Since 90% of BF POSIT’s work is performed for the Croatian Railways as a customer, it is very important to achieve customer satisfaction with the quality of work, and to meet deadlines.

At the Croatian Railways there are plans to invest in the modernization of railway lines, including the SS units, which means that the expectations of BF POSIT as the main company for the installation of these devices is high.
