This course provides insight into the signaling systems and equipment used for control and security of railway traffic. The course covers the requirements and conditions that are the basis for the railroad signal system. It also deals with both the components and complete systems to current and future signal systems are constructed.

Intended learning outcomes
After the course the student shall be able to:
- Explain the need of a signaling safety system for the railway
- Explain the interaction between trains, railway and train traffic control centers
- Describe the difference between current and future signaling systems
- Explain the different design of a signaling system dependent on infrastructure

- Calculate the cost of a designed signaling safety system
- Describe the current law and regulations in the signaling safety system
The course consists totally of twelve days of lectures by the basic knowledge needed to understand the subject. This is supplemented with exercises, project assignments and field trips to provide applications on the subject. Examination is a written exam. The course can partly be read at a distance.
Literature and preparations
University studies at least 120 credits and Eng B/6 according to the Swedish upper secondary school system.
Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
- TEN1 - Examination, 7.5 credits, grading scale: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
TEN1 - Examination, 7.5 credits, grade scale: A, B, C, D, E, FX, F
Other requirements for final grade
A mandatory written examination equivalent to 7,5 cr with grading scale A-F
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
