SECURITY AND PROBABILITY IN RAILWAY SIGNALLING

To ensure that a system is safe in spite of the failure of components, it is built on the fail-safe principle. Probability calculations do not allow this principle to be abondoned for they can only deal sufficiently accurately with part aspects. Probability can also easily lead to over-dimensioning and hence to un-economical solutions. It also puts high demands on manufacture and maintenance; probability calculations are applicable in cases where random and independent events coincide.
