The project of the computer-based interlocking (ACC) of Pisa to Tyrrhenian line and the Florence-Pisa-Livorno line of the Italian railway network was developed by Italferr S.p.A. The interlocking plant was to group together the stations of Pisa Centrale, Pisa S. Rossore, and Pisa Airport in its final configuration, forming a single large plant, removing the intermediate block sections, and reorganizing the traffic flows of the different related lines. The object of the contract included design, construction, and commissioning of the ACC. It also included the new power supply systems of the medium-low voltage ACC cabins, the integrated selective telephony system, the Public Information System, and modification of the Command and Control System (SCC) of the Tyrrhenian line and the other sub-systems interfaced with the new ACC.

The paper illustrates the characteristics and operating modes of the emergency traction power supply system implemented on the Bologna - Florence line of the Italian High Speed network which is electrified at 2x25kV, 50Hz. The paper first describes the main characteristics of the equipment installed, the design criteria and power supply scheme. The paper goes on to outline the challenges of power quality associated with the connection of a heavy single phase load to the Medium Voltage (MV) network. The effectiveness of the installation and the evaluation of voltage unbalance compatibility levels compliance are then presented. ©2010 IEEE. Source

The preliminary study developed for interconnections planned between the new High Capacity railway line Turin-Lyon (NLTL) and the Conventional line on the Italian territory that have different voltages is discussed. The new Turin-Lyon railway line represents a fraction of approximately 220 km of an entire railway backbone of over 4000 km between Lisbon and Kiev identified as 'Corridor 5' on the TEN network. A voltage separation section is a singular point and is the subject of particular signaling, whose installation must enable the driver/system to intervene correctly. The POC crossing checks were made for trains moving uphill from NLTL to the historical line (LN > LS) through the down interconnection. The study recommends that one should keep in mind that in the design practice, where there are territorial insertion problems that do not allow full application of design standards, the system configuration is adapted to infrastructure needs while respecting the performance requirements.

The excavation of a tunnel in highly weathered and strongly fractured rock masses due to tectonic actions is still a challenge. In order to maintain reasonable productivity, excavation through a wide zone of highly tectonized rock mass requires a detailed, integrated study of the construction solutions and a monitoring system to minimize the process time and to optimize the adopted consolidation measures in accordance with a predefined matrix of possible support systems. This paper summarizes some interesting data acquired during the excavation of the Brenner Railway Base Tunnel system between Italy and Austria. The Brenner Base Tunnel (BBT) runs through the fault line between the European and the African tectonic plate. This big fault zone is called "Periadriatic Line." In particular, data acquired in the exploratory-service tunnel have been analyzed. Furthermore, the base concepts for defining the consolidation and support solutions adopted for the excavation of the exploratory tunnel are described.

Researchers examine the impact of carbon dioxide (CO2) emissions of the c on the environment through the case study of italferr. The researchers find that that it is necessary to determine the source of such CO2) emissions in the CO2) to take corrective measures. Data relating to other activities that produce emissions are detected by using internationally recognized sources or by direct analyses deriving from the experience gained by italferr over a period of time. The findings of the investigations also reveal that the cement industry is fully aware of its responsibility in the global effort to deal with the challenge of climate change due to such emissions.
