Improvements in the design and structure of train-tanker cars after a fatal propane blast on July 5, 1973 in Kingman, Ariz., may have helped to avert a possible catastrophic blast last month in Lincoln, Calif., Kingman Fire Chief Chuck Osterman said. Train-tanker cars "are double-walled now, to help absorb any flame impingement, and revalved. They beefed up the bulkheads in front and in the rear," he said. Improvements in the way firefighters handle such incidents also contributed to the successful operation, he said.
