On 12 August 2011, an express train travelling from Warsaw to Katowice in southern Poland derailed at Baby, near Piotrków Trybunalski, killing one passenger and injuring 80 others.

On Friday, 12 August 2011, a PKP Intercity TLK train from Warszawa Wschodnia to Katowice derailed at Baby [ˈbabɨ], near the town of Piotrków Trybunalski.

Initially, four passengers were reported dead,[1] but search of the wreckage with the use of lifting equipment and rescue dogs established that only one 52-year-old man had died.

The train was full, carrying almost 280 passengers, as the accident happened on the Friday before the long weekend of the Assumption Day holiday.

In such circumstances, the driver should be acquitted according to in dubio pro reo rule,[7] which was also used by Polish court during one train crash case in the past.
