Tempi: The explosion is due to cables along with silicone oil says new finding

In the light of publicity one more expertise about explosion and fireplace After the fatal conflict in Tempi.

With the data that existed then, the technical report by experts, appointed by the 23 -year -old family Iphigenia Mitskastates that the fire it was the cause for which many passengers were charred and started by Cutting cables of power of electraxes, voltage of 25,000 Volt in combination with the silicone oil of transformerswhich scattered all over the accident.

What caused the deadly fire – How spread to wagons

Specifically, in the technical report 51 pagessigned by experts Stelios Kakamoukas and Nikos Kakamoukascome to the conclusion:

“The fire, which, in our estimation, was also the reasons for many passengers of the passenger train, were charred and which started from the electrical discharges created by the cutting of the power supply of the electraxes, a voltage of 25,000 volts, in combination with the oil.

Finally, the fire spread through the materials of wagons such as fabric seats, wooden lining, floors and sides and foam seats. “

Responsibilities to Station, OSE and TRAINOS

According to the report, the responsibilities for the tragedy in Tempi bear the following:

“A) The Commander -in -Chief of the SS Larissa, who:

• He did not use the engraving operation (as defined by a document from the OP EU traffic management) which would ensure the course of the train on the rise line.
• Not Checked at all the status of key No 118 on the line before departure from SS. Larissa, so that in the course of the train it continues to move on the rise line.
• He did not examine the course of the train heading to Thessaloniki through the local manipulation table, which was within its range, to make sure of the proper move of the passenger train.

B) The passenger train driverwho, on the one hand, did not inform the SS Commander at all. Larissa for the train entrance to the descent line, even with the few media such as the wireless, on the other because while he realized that the photocopy was not working AT ALL During the pre -accident time, he continued to move in the descent stream.

C) Safe drive systems which include the sealing control systems and light traffic lights which (systems) They did not work. If they were working right then the tragic accident would not happen.

Also, the responsibility also bears the OSE. Also, the ETCS system did not work, which, although installed on the train, practically never existed. In the case of this European system, the tragic accident would not happen.

D) the responsible and the TRAINOSE which was responsible for maintaining trains as Did not practice the required maintenance on the trains and in particular on the seat in the 3rd wagon at position 67 where the 23 -year -old was sitting unlucky IFigenia Mitska which, due to the incomplete maintenance, was detached from its base and Iphigenia Mitska was ejected, resulting in a tragic death.

(E) Each third party who was responsible for the exercise of supervision and control of the proper operation and maintenance of the rail network and trains. “

What did the analysis show from state chemistry

According to experts designated by the Larissa Traffic Department, during the autopsy carried out about a month after the tragic accident both at the scene of the accident and in the wreaths of the wagons, samples were collected from “dangerous substances by analysis by analysis by analysis by State chemistry proved to be:

A) silicone oil: Silicone oil which was the transformer oil, is mainly used as lubricants or hydraulic fluids. They are excellent electrical insulators and depending on the amount of carbon, they are not flammable. Their temperature stability and good heat transfer characteristics are widely used in the laboratories placed over heated shakers, as well as in freezing dryers as refrigerators.

Silicone oils are also often used as damaged liquid, dry types of transformers, diffusion pumps and oil heaters, while their ignition point is over 300 degrees Celsius. During the burning of silicone oil, gases such as hydrogen, methane, ethene, ethane and acetylene are all extremely flammable.

The cover of most of the wagons with this oil was also the cause of the spread of the fire, since during the destruction of transformers, silicone oil was scattered around many parts of the accident.

B) battery liquidswhich are a dense solution of potassium hydroxide, which cause severe burns. “

Communications and security systems

“All the trails of the trains of the train had the ETCS elements mounted on the train that had been received between ERGOSE and GAIAOSE on 07/2018.

Indeed, the railway line where the tragic accident took place had radio, but their operation has been certified, “as noted.

“So, since both streams and descent streams did not operate the seizure of the line fields and the photocopy and since in the line where the accident took place with the trauma deactivated elements, we conclude that the operator of the passenger travele Opposite traffic stream, except at the last minute.

The GSM-R is a radio system for providing voice and data communication between the line and the train, based on standard GSM using frequencies intended for rail applications with certain specific and advanced features. This system facilitates communication between mechanic and station or traffic control centers, providing specific features such as fan communication, emergency calls, etc.

Its structure is based on GSM antennas, that is, mobile telephony companies even at high speeds. The main reason for the creation of such a system is very large because it enables the addition of exchanging information between trains and telecommunications centers.

Along the railway, there is only a GSM-R network of voice that allows for the communication of stations and trains, but unfortunately a mono is used by the stations as the trains were never equipped with such a device. “
