We continue to clean out my late mother's home and my wife discovered two old Chicago newspapers I'd set aside as a teen. On the morning of October 30th, 1972, the Illinois Central suffered a terrible crash of commuter trains in electrified territory at 27th Street in Chicago when a train of old heavyweight mu cars telescoped the rear of a train of new lightweight bi-levels. The lightweight train overshot the platform which was a flag stop. Amazingly, the lightweight train stopped and made a back up move to the platform, and without flag protection. The backup move set a restricting signal in the block, but the heavyweight train had already passed the signal and had no knowledge that the block was occupied.
