Basic information
Level of Studies: Undergraduate applied studies
Year of Study: 2
Semester: 4
Requirements:
Goal: The aim of the course is for students to acquire theoretical and practical knowledge of railway telecommunications, control and signalling devices, and modern railway network systems in order to their practical application and proper use.
Outcome: The student got acquainted in detail with signalling and safety devices and is ready to improve the system for their maintenance. Knows the basics of telecommunication devices and understands their role in signalling and safety systems. The student is prepared to adopt to the process of working on the railway. Preparation for professionally applied subjects and work in the railway profession.
Contents of the course
Theoretical instruction:
  1. Characteristics of railway telecommunication (TK) plants: TK connections for ensuring safety and regularity of railway traffic, principles and characteristics of TK railway transmission systems: TK connections in decentralized, indirectly centralized, and centralized traffic - telecommand.
  2. Railway TK transmission systems: a model of a communication transmission system, methods of communication by electric means, connection systems using physical media
  3. Data transmission: synchronous and asynchronous mode of transmission, computer networks, and the Internet
  4. TK lines, metallic and optical, metallic and optical line properties, lineside, signal and local cables, influence and protection of TK lines from dangerous and disturbing electric traction current influence
  5. Railway TK devices: telegraph-telefax devices, telephone devices, station and rail analog and digital devices, dispatch telephone devices, radio devices, KT, UKT and RR radios, mobile RDUs and GSM -R, clock, information systems, recorders, public address, intercoms, and access control devices
  6. Railway TK networks: railway telephone switching networks-ZAT networks
  7. The role and mission of signalling-safety (SS) plants on railways
  8. Station SS devices: signals, types of optical systems, switches and derailers, technical means for securing switches and derailers, relays, contact and contactless components, devices for controlling the occupation of the station section, track circuits, internal station SS devices, classification of station signalling boxes (interlocking), table dependencies -free scheming, route plan -mosaic technique, electronic interlocking
  9. Lineside railway SS devices: devices for continuous and punctual control of railway sections, regulation of traffic at the inter-station distance by check-ins, MZ (interstation dependencies) and APB (block) devices, devices for securing level crossings (PP), devices for transmitting information from the railway to the locomotive
  10. Automatic control systems in SS technology: shunting station automation, devices for automatic placement of switches, devices for detecting the axle bearing heating
  11. Remote control of railway traffic - traffic telecommand: control desk, control panel, satellite devices of telecommand in the station, computer in the system for automatic traffic management, SCADA systems
  12. Electronic interlocking and basic principles of ETCS on European railways
  13. Microcomputer control of marshalling yards.
Practical instruction (Problem solving sessions/Lab work/Practical training):
  1. Discussion - auditory exercises and performance of demonstration exercises at the Railways locations in Serbia
