The paper presents a fail-safe railway interlocking system embedded in an Area Control Center (ACC) system. The host of the system is a TANDEM NONSTOP HIMALAYA K200 computer. The fault tolerant computer aims at high safety, reliability and availability. In addition, the dispatcher management system, device supervision system, and train control system are integrated in the host computer to ensure high performance. Tens of stations can be controlled by the system concurrently. The paper also presents some measures in the software used to ensure safety of the interlocking system. These measures have been verified by practical applications in old versions of the interlocking system.
