  1. A safety system is built with redundancy and layers of automatic checks and operation procedures to prevent a “Single Point of Failure” causing a disaster. A critical signal sensor should have redundancy sensors to detect a failure. The Indian railroad system is plagued with poor maintenance, inadequate safety backups, poor operating procedures, and poor training.
