A total of 24 people were killed and 300 others were injured after a train came off the rails in Turkey's northwestern province of Tekirdağ.
The train, carrying 362 passengers, came off the rails after "heavy rain and a landslide" on to the tracks, Turkish officials said. But critics say the derailment could have been prevented. Experts from a Turkish engineering union issued a statement saying a drainage system was incorrectly built.
The union added that the government has cut costs, including eliminating route inspector jobs about five years ago. It said that inspectors would have identified the collapsed ground and stopped the train before it reached that section of track.
Critics on social media shared pictures of the eroded land below the train tracks, saying the infrastructure was poor and the railroad was not properly maintained.
The Turkish government has ordered a temporary media ban Sunday on news coverage of the train derailment, citing national security and public order.
The rescue operation at the site of the crash finished at 06:00 a.m. local time (03:00 GMT).
The evacuation of the injured had to be carried out with the help of helicopters and tractors because of bad roads.
The train was heading to Istanbul from Edirne, on the border with Greece.
The Ministry of Transport said five of the train's six cars derailed.
Country's rail network has been hit by several fatal accidents over the last years. Turkey's worst recent rail disaster, 41 people were killed and 80 injured in July 2004 when a high-speed train derailed in the northwestern province of Sakarya.
