The first investigation by prosecutor in Trani for railway engrave in Puglia Monday, July 12 are the station masters of the stations of Andria and Corato – where the two trains passed that clashed shortly after in is single track that connects the two stations, killing at least 23 people and wounding 52 – and, writes the Corriere della Sera , an “employee of Ferrotramviaria society, someone who would have a different role.” at the moment it is still unclear what exactly caused the accident: the most likely hypothesis is that there was a communication error between the station masters of Andria and Corato, who brought two trains traveling on the same It is single track at the same time. In the section between Andria and Corato, in fact, there are no automatic safety systems for trains block; the communication between the two stations is via a phonogram, that is a communication that passes through the telephone lines. The phonogram is associated with a different color of the traffic lights for the train, which is operated by the station master, who in most signals the driver of the train when it can start with a shovel. The station masters of Andria and Corato, meanwhile, have been suspended from duty. Vito Piccarreta, the station master of Andria, told Republic had gave the green light for the departure of a train to Corato without knowing that in the other direction was already getting another train, and said that Monday was a day of long delays that had complicated the traffic management work. It also seems that on Monday from Corato are two trains parties in succession: the first arrived in Andria regularly while in the train station waiting for the matches in the opposite direction, the second was instead involved in the clash, because in the meantime the waiting train to Andria had received the green light for the start. That the problem was the party from Andria train it was also confirmed by the public prosecutor Francesco Giannella, who is coordinating the investigation: “It is evident that the train that left for the second, was not to go. This has happened because we are experiencing. “ Republic also told that on the line where the accident occurred, the Bari-Barletta managed by the private company Ferrotramviaria (and not so by Ferrovie dello Stato), in recent years it had increased a lot the number of trains in circulation and therefore the traffic to manage. For the management of delays, always says Republic , it was not uncommon that were circulated additional trains and not provided by the normal Monday morning, when the accident occurred, it was scheduled in that time slot the passage of three trains and not two as is normally done. The Bari-Barletta line, however, was considered efficient, told Sky . Many of the trains were traveling were quite modern – those involved in the accident were the 2005 and 2009 – and in general there were few delays, clean carriages and a good service. The investigations are carried forward from Trani attorney, a city that is located not far from Andria and Corato, on the coast, just north of Bari. the Corriere del Mezzogiorno has written that there are five judges who deal of ‘investigation’ in addition to the acting prosecutor, Francesco Giannella, the pool is composed of the prosecutor Antonio Savasta, Simona Merra, Marcello Catalano and Michael Ruggiero “. The crimes of which they are currently investigating culpable rail disaster and multiple manslaughter, and the newspapers are saying that the investigation will also cover the delayed modernization of the line, for which the doubling had been allocated the funds several years ago but without the to depart work. One of the things that have been the most talked about in the newspapers these days is the issue of single track, which especially in the hours after the accident was presented as its main cause. In fact in Italy it is single track more than half of the railway network operated by Italian Railway Network (RFI) – a company wholly owned by Ferrovie dello Stato – and are about 6000 km network of 6,500 operated by third parties on granting of RFI. What seems to have caused the accident in Puglia is the security system that prevents two trains in traveling on the same route in the opposite direction: the “Telephone lock” is an old and already considered inadequate by European safety standards system. the Daily explained that the lines managed under concession and those managed directly by RFI respond to two different security agencies: “All trains that move on the RFI network They must respond to the ANSF stringent criteria, the national Agency for railway safety, independent organization responsible for issuing licenses and controls. Those who work on the sidelines as a controller has the USTIF, the Special Office for fixed installations transport, a peripheral body of the Ministry of Infrastructure and Transport organized in 7 interregional divisions that has obviously reliable but less stringent rules. ” On the network of RFI, for example, they are no longer permitted routes operated with the telephone block and are necessary wherever the automatic traffic control systems that can also block the trains in case of driver error. In the few cases where they are not yet automated systems on the RFI network service “is expected to double in the operator cab and the degradation of” speed, while the networks operated under concession and controlled dall’Ustif is still permitted the telephone block. the reason for the discrepancy, always says the Daily Done , is that when between 2007 and 2008 was created the ANSF much of the Italian network managed under concession would not comply with the new safety standards and should have been closed to traffic waiting to substantial and costly modernization works. Why the two agencies were created and was left even more time to private companies to carry out investments without risking the closing and interruption of service. On the route where the accident, for example, chances are they are missing on the tracks the technological systems that interact with the trains to operate the control systems and automatic locking happened: although the trains were new and equipped with the safety systems required by ANSF standards, then, they could move even on sections of the railway where the operation of those systems was virtually impossible. The Bari-Barletta line is not entirely devoid of most modern safety systems of the telephone block, but it is the section between Andria and Corato.
