Safety is of utmost importance

KLC3 system

KLC3 system is a level crossing protection and signaling system. The system can be activated in a number of ways: when train activates activation contacts, by command from the station or locally.

The basic components of the KLC3 system are:

  • KLC3-SP – KLC3-Safety Platform,
  • WESS – Wayside Equipment Subsystem,
  • TDSS – Train Detection Subsystem,
  • RCSS – Remote Control Subsystem,
  • DLSS – Data Logging Subsystem.


KLC3-Safety Platform (KLC3-SP) is the central logic subsystem of Končar’s LC. It consists of two identical safety subsystems – channel A and channel B. Channels A and B are electronic systems connected to each other by an optical serial communication bus. Communication between channels A and B enables the exchange of information on the current state of each channel. In the event of communication failure, the system enters the safety state. KLC3-Safety Platform receives information and commands from the TDSS, WESS and RCSS subsystems, and on their basis controls the light signaling, sound signaling and half barriers.


The KLC3 central logic device for level crossing protection and signaling is the third generation of Končar’s devices for such purpose. It complies with the CENELEC standard of the highest safety level – SIL 4.

The ability to configure and use the interface with various external devices ensures a wide range of device application and adaptability to different markets.


Electrical point heating

The essential condition for safety and the possibility of traffic in winter conditions is the correct operation of points in railway stations. During low temperature conditions with severe and frequent precipitation, snow and/or ice deposits form between the stock rail and point blade, which prevents them from linking, and thereby prevents the control, i.e. confirmation of the end position of the point.

Our solution for the problem is the installation of electric point heating in order to raise the temperature of the metal parts of the point and prevent the formation of snow and ice deposits.
