2. Objectives and learning outcomes
2.1 Objectives
The objective of the subject is that the students get familiarized with basic concepts of railway tracks, types, requirements and major technical parameters of its structural elements, geometry of the tracks, most important design criteria, types of turnouts and crossings, and the with the basic concepts of railway stations.
2.2 Learning outcomes
Upon successful completion of this subject, the student:
A. Knowledge
  1. will learn the most important basic characteristics of railway transportation (passenger only, mixed, freight only, conventional, high-speed, urban, etc.)
  2. will learn the history and development of the railway transportation, and current development strategies,
  3. will learn the basic concepts of the railway tracks and vehicles, such as clearances, gauge, etc.)
  4. will learn principals of movement characteristics, speed, acceleration, changing of acceleration,
  5. will learn principals of geometrical design of the railway tracks, curves, transition curves, super-elevations, superelevation tansition,
  6. will learn calculation of surveying of railway lines, staking of major points and details of curves and transition curves,
  7. will learn the most important criteria of horizontal and vertical design parameters of the railway tracks,
  8. will learn the types, materials and requirements of structural elements, such as rails, sleepers, rail fastenings, ballast, rail joints, welding of rails, structural elements of highway crossings,
  9. will learn the types of turnouts, crossings, double slips, their geometrical parameters and struc-tural elements, (radius, deflection, angle of deflection, velocity, etc.)
  10. will learn calculation and geometry of simple track connections,
  11. will learn the types and basic concepts of railway stations, track types, stations, passenger plat-forms, facilities for loading of freight, marshalling yards, etc.
  12. will learn categories of urban railway railways, such as networks, track geometry, types of struc-tural elements
  13. will learn principals of horizontal layout, vertical sections and cross-sections of railway lines
B. Skills
  1. will be able to distinguish and recognize different categories of railway transportation, to select appropriate category of railway lines,
  2. will be able to understand principal geometrical designs of tracks in horizontal and vertical as-pects,
  3. will be able to understand movement characteristics, and geometrical elements of railway lines,
  4. will be able to identify and select the most important structural elements of the railway tracks for applications,
  5. will be able to understand surveying of railway lines, staking of cardinal and detail points of cir-cular curves and transition curves,
  6. will be able to perform a simple design task.
