Two trains are travelling in opposite directions, one headed eastbound at 48 kilometres per hour and another westbound at 80 kilometres per hour, before sideswiping each other at a railway crossover in midtown Toronto. Why did the westbound train operator see the stop signal so late? New details emerged Monday as officials looked into the crash that left four rail cars leaning and damaged the tracks. Neither train was speeding, the Transportation Safety Board says, and CP Rail ruled out mechanical problems, instead pointing the finger at human error, something it reiterated on Monday. On Monday, the union representing CP Rail workers called that conclusion "premature" but said it understands two of its workers are being investigated.
