The Soviet Union's deadliest postwar train disaster occurred 30 years ago, claiming 575 lives and injuring 800 -- according to official figures. The cause was a powerful explosion of gas that had leaked from a nearby pipeline, estimated to be the equivalent of 10,000 tons of TNT. Two trains, carrying vacationers to and from Black Sea resorts, were affected.
