And you thought it was hot where you live.

97 Injured in Md. Amtrak Crash (washingtonpost.com) Moments before the accident, the engineer told officials, he saw track that had heaved to the side, Amtrak sources said last night. Extreme heat sometimes can cause such a condition, which railroaders call "heat kink." The temperature in the region at the time of the accident was recorded at 96 degrees.

"We know it's possible with continuous welded rail," said Carol Carmody, vice chairman of the National Transportation Safety Board, which dispatched investigators to the scene. She said heat can cause "a slight mishap or buckling." It could take months for the panel to identify the cause of the accident.
