George Black, a member of the National Transportation Safety Board, said investigators are impressed with how the
double-deck Superliner cars remained intact even though they were pounded with massive forces.
Unlike airliners, which are built of lightweight aluminum and composite
material, rail passenger cars are built of heavy steel. This factor alone often
prevents deaths or major injuries in even high-speed train wrecks.
"The good story is that the cars stood up like champs," Black said.
