The 12-carriage cargo train transporting wheat from Hungary and some containers from Croatia derailed near the Drivenik station at the Fuzine-Rijeka railway section. No one was injured in the accident.
Brkic, who is the head of a crisis team set up to establish causes of the incident, said that a preliminary report on the accident would be compiled in ten days' time.
The train reached the speed of some 130 kilometres per hour before it derailed although the speed limit was 60 kilometres per hour for cargo trains at that section.
Reporters asked Brkic whether the decrepit railway infrastructure could be the cause of the accident, and he answered that this April an inspection engine checked the section and found no faults.
The HZ has a network of 2,800 kilometres of railway lines. Of this length, 355 kilometres of tracks are old up to five years, 384 kilometres of tracks are old between five and 20 years; 925 kilometres of the infrastructure are older than 20 years, and 599 kilometres of tracks are older than 30 years.
The president of the HZ company's managing board, Tomislav Josip Mlinaric, who toured the site of the accident on Monday, said that the derailment could be beyond any doubt ascribed to excessive speed.
