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.

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.

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 present paper describes the development and the evolution of the systems supplying power to the railway technological installations with a specific regard to the in-tunnel emergency plants (fig.1) and the relevant new regulations. The analyses and the consequent design choices applied to the High Speed Lines in operation and in future construction are here illustrated.

The paper presents the new high-speed railway station in Bologna: a great and innovative work integrated into a large infrastructure project of reconfiguration and upgrading of the rail junction city, one of the most imno, uno dei più importanti d'Italia. Dopo aver richiamato i requisiti "funzionali", sia sotto il profilo urbanistico che trasportistico, la memoria descrive il progetto illustrando il "concept" architettonico e strutturale, entrambi inquadrati nello specifico contesto territoriale, geotecnico e idro-geologico. Successivamente vengono descritte tutte le principali componenti dell'opera: il camerone ipogeo con le particolarità compositive e distributive; le particolari e, per molti aspetti, innovative opere di contenimento delle terre: gli speroni (paratie con sezione a T), le voltine e la trave di coronamento; i telai trasversali e i solai di piano. L'illustrazione si conclude con la descrizione delle principali caratteristiche degli impianti e delle finiture architettoniche. A conclusione della illustrazione del progetto ci si sofferma sulla forte interrelazione fra tutte le componenti specialistiche coinvolte nello sviluppo di questo tipo di progettazioni e sulla necessità che esse debbano essere concepite e sviluppate in modo integrato e sinergico.

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.

The auditing activity on an organization's management systems, as indicated by the UNI EN ISO 19011 guideline, foresees an encoded and rigorous survey method allowing a qualified auditor to develop a detailed knowledge of what the organization subject to audit has put in place, to the extent of being able to assess the conformity or not to standards that set out the requirements that management systems must have. Each type of organization of any production sector can achieve the compliance of its activities with the UNI EN ISO 9001, UNI EN ISO 14001 and BS OHSAS 18001 standards of the management systems. A first phase of integration and control of management systems in construction sites saw Italferr concentrated on the qualification of resources, on the construction of the controller-controlled interface, in training on the conduction of audits, in the progressive and thorough study of the standards aimed at their authentic interpretation.


The realization of the High Speed/High capacity (HS/HC) urban crossing line in Bologna has provided the opportunity to reorganize the entire railway structure through the construction of the new underground station and important engineering works, such as new bridges on the Reno and the tunnels that run underground the city for over 10 km. The new IHS train station will therefore be underground, but in correspondence of the current station, maintaining the advantage of being centrally located, near the historical center, and ensuring an easy interchange between the fast trains and regional ones. The realization of the vaults has foreseen the execution timeline of two semi-vaults each composed of 3 diaphragm panels, whose tracking in the layout has allowed to determine the low arch geometric conformation required by the project.

The 4c segment is a part of the "Oman National Railway Project" linking the mining area in the surroundings of Thumrait and the port of Salalah. It is 90 km long and the last 40 km stretch crosses a mountainous area near the city of Salalah. The project includes the excavation of a 33 km double and single bore tunnel and 10 km of safety tunnels. This mountainous area is a holiday destination for Omanis, thanks to its beautiful landscapes, especially in summer time due to the monsoon rains. The tunnelling design had to take into account both these environmental constraints and the limestone rock formations crossed, which are affected by significant karst features. Given the context, the conventional tunnelling method has been preferred.

Genoa is a very distinctive city located between mountains and the sea and infrastructural upgrading works often have to deal with the intersection of existing infrastructures. This is the case for the new railway tunnel construction between the stations of Brignole and Principe which under-cross two existing double-track tunnels in operation. The latter have been constructed with masonry bricks and the vertical distance between old and new tunnels is approximately 1m. Due to rock characteristics and the urban environment, stability and vibrations control are the main issues. Consolidation work with the fore-poling method and a specific sequence of excavation, primary lining and final lining support have been designed to assure stability and settlement control. A hard rock road-header has been used to assure vibration control. Finally, a real time monitoring has been implemented. The article presents monitoring and back-analysis results of the under-crossing of the existing tunnels. Copyright © (2016) by the Society for Mining, Metallurgy and Exploration.
