Fundamentals of Railway Train Control and SignalingSee upcoming dates
Upon completion of this course, you will be able to:
- Describe manual block signaling, automatic block signaling, and vital circuits.
- Identify the signaling principles related to system capacity, layout and headways.
- Explain TCS (Traffic Control Systems) and ATC (Automatic Traffic Control).
- Identify and illustrate multiple track circuit technology.
- Explain the purpose of an interlocking and define the four types of basic switch locking logic that assures safe operation.
- Describe and illustrate the general architecture and operation of a PTC system.
- Describe the similarities and differences between in PTC technologies including IETMS, ACSES II, and ITCS.
Who Should Attend?
This entry-level course will teach you about the base systems architecture and function that are the foundation of signal and train control systems and PTC.
