ERICSSON Safety System for Railway Control

  • Gunnar Hagelin
Part of the Dependable Computing and Fault-Tolerant Systems book series (DEPENDABLECOMP, volume 2)


Traditionally, equipment used by railways have been grouped in vital and non-vital equipment. Vital equipment shall work in a fail-safe way. Interlockings and level crossing units are examples of vital equipment, and the train dispatching panel is an example of non-vital equipment.
