ELECTRONIC INTERLOCKING TO BE TRIED IN JAPAN

Early in 1981, the interlocking at Ishiuchi on the Joetsu Line of Japanese National Railways will be performed by computers, working in parallel with a conventional relay interlocking so as to check the integrity of the new technology under field conditions. System design avoids the need for a large number of programs by aggregating non-vital tasks, while reliability and safety are assured by two-out-of-three voting in a triple-redundant system. In addition, fail-safe fault detecting functions watch for component malfunction and shut down the subsystem affected, thus protecting overall safety.
