At the moment, 124 people are being treated in hospitals, the NTV broadcaster reported, citing Health Minister Ahmet Demircan.
Previous reports suggested that slightly over 70 people had been injured after five cars of the train went off the tracks in the province of Tekirdag.
The rescue operation at the site of the crash finished at 06:00 a.m. local time (03:00 GMT).
According to the Turkish Transport Ministry, the crash was caused by the heavy rains, which weakened the soil under the tracks. The evacuation of the injured had to be carried out with the help of helicopters and tractors because of bad roads.
