Infratrasporti.To S.r.l. (Infra.To) is a company owned exclusively by the City of Turin. The purpose of the company is to own and manage existing infrastructure and to plan and construct new infrastructure, including railways for passenger and freight transportation (both public and private) in accordance with legislation governing the operation of state-owned companies. Infra.To owns Line 1 of the Turin automatic underground system (13.2km) and the N. 4 Tramway line (18km).

Infra.To is currently involved in a number of works on the Turin underground system, including:
● Planning and construction of the Lingotto– Bengasi stretch of Line 1
● Planning of the Collegno–Cascine Vica stretch of Line 1
● Planning of the connection of the Torino– Ceres railway line to the Turin railway by tunnelling the line in Corso Grosseto
● Participation in the study group for the transport and financial planning of Line 2 of the Turin Underground
● Planning of new lines and renewal interventions for the city of Turin tramway infrastructures and regional railways.

Assessing fire development in underground metro cars

Issue 2 2011  •  6 May 2011  •  Professor Haukur Ingason, Senior Research Scientist, SP Technical Research Institute

In the fire safety design process for underground metro systems, the design fire is usually an issue that requires long discussions and consensus among designers. The main reason is the complexity of fires in metro cars and lack of large scale test results which confirm the design assumptions. This article gives an overview of fire development in underground metro cars and gives an insight into a large scale test series that is planned for autumn 2011 in Sweden.
Increased demand for mass transport

Rapid advances in underground construction technology and increased demand for mass transportation of people force us to build more-and-more complex underground mass transport systems. The fire risks and conse – quences of fires usually become key issues in the design process.

Evaluating safety aspects for underground metro networks

A functioning mass transit system is most important to back up mobility in large cities and conglomerations. This has been recognised for nearly 150 years: the first metro worldwide was inaugurated in London in January 1863. It was a steam driven system. The first electrified trains started in November 1890, again in London. The first metro on the continent followed in 1896 and was installed in Budapest. Paris started its metro in 1900, Berlin in 1902 and Hamburg in 1912.

The size of the route network depends on the population of the city or the area served by the subway system. London operates its underground network with a length of 410km and 270 stations – by far the largest network in Europe (and worldwide), followed by Madrid with 325km, Moscow with 300km and Paris with 215km.
