Will Rail Take the Strain When News analysis Will rail take the strain when What will happen to transalpine traffic when the Gotthard road tunnel closes for maintenance work? Can rail take the strain from the roads on this vital axis, and if so, how? Regional editor Anitra Green takes a look at the possibilities and the wider implications. VEN if the Swiss say yes E to the construction of a second SFr 3bn ($US 3.1bn) Gotthard road tunnel when they go to the polls next year, it is widely assumed that it cannot possibly be ready for operation before the existing tunnel closes for essential maintenance work, which ideally will happen between 2018 and 2020. Studies have been completed and plans are already being drawn up for rail transport to carry the vast amount of traffic that uses this route. The Gotthard Base Tunnel is due to open in 2016 and the existing mountain route will be retained Airolo, while lorries, buses to the Lötschberg route or Kandersteg and Goppenstein. for regional and tourist services, and other large vehicles would setting up a longer rolling road BLS has already made it clear as well as for other freight and travel on a rolling road service service (eg Basle - Lugano/ that it is prepared to offer its passenger traffic if required. through the base tunnel Chiasso) would not cover expertise and resources on the According to a study by between Rynächt/Altdorf and regional needs.

  • Effective Firefighting Operations in Road Tunnels
    Effective Firefighting Operations in Road Tunnels Hak Kuen Kim, Anders Lönnermark and Haukur Ingason SP Technical Research Institute of Sweden Fire Technology SP Report 2010:10 Effective Firefighting Operations in Road Tunnels Hak Kuen Kim, Anders Lönnermark and Haukur Ingason The photo on the front page was provided by Anders Bergqvist at the Greater Stockholm Fire Brigade. 2 3 Abstract The main purpose of this study is to develop operational procedures for fire brigades in road tunnels. Although much progress has been achieved in various fields of fire safety in tunnels, very little attention has been paid specifically to fire fighting in tunnels. This study is focused on obtaining more information concerning how effectively the fire brigade can fight road tunnel fires and what limitations and threats fire brigades may be faced with. This knowledge can help parties involved in tunnel safety to understand safety issues and enhance the level of fire safety in road tunnels. The report is divided into three main parts. The first part consists of a review of relevant studies and experiments concerning various key parameters for fire safety and emergency procedures. The history of road tunnel fires is then summarised and analyzed. Among all road tunnel fires, three catastrophic tunnel fires are highlighted, focusing on the activities of fire brigades and the operation of technical fire safety facilities. In the second part specific firefighting operations are developed. This has been based on previous experience and new findings from experiments performed in the study. In the last part, information is given on how the proposed firefighting operations can be applied to the management of fire safety for road tunnels.

  • Selection of the Optimum Tunnel System for Long Railway Tunnels with Regard to the Entire Lifecycle
    SELECTION OF THE OPTIMUM TUNNEL SYSTEM FOR LONG RAILWAY TUNNELS WITH REGARD TO THE ENTIRE LIFECYCLE H. Ehrbar & C. Tannò ETH Zurich, Switzerland H.-P. Vetsch Vetsch Rail Consult, Bützberg, Switzerland ABSTRACT: Since more than 30 years long tunnels with a total length of more than 50 kilometres exist. Many of them show a different tunnel system: double track tunnels with service tunnel, two single track tunnels and two single track tunnels with a service tunnel are the existing systems. The decision on the tunnel system of this long tunnels had to be taken at a time when only few information on operation and maintenance costs were available. Today more information on oration a maintenance is available. The paper shows, how the decision-making process should be made today considering the criteria construction, operation and safety with regard to the entire lifecycle. Recommendations on the selection of the tunnel system will be given for different boundary conditions, based on the operation experience of the long tunnel railway tunnels under operation. 1. PROJECT REQUIREMENTS OF LONG RAILWAY TUNNELS Railway tunnel constructions have the purpose of connecting cities, economic regions (Gotthard-Base Tunnel), countries (Eurotunnel, Cross Border Base Tunnel under the Ore Mountains) or even continents (Gibraltar Strait Tunnel) in order to ensure a rapid and environmentally friendly transport of people and goods. Mountains or straits are the typical topographical obstacles that must be overcome with a tunnel. Such tunnels become quickly very long (> 20 km length) due to special topographic boundary conditions for mountain base tunnels and strait tunnels. Figure 1: Longitudinal profile of a subsea tunnel (Eurotunnel) and a mountain base tunnel (Gotthard Base Tunnel) (source Wikipedia and AlpTransit Gotthard) Very long tunnels have to fulfil many project requirements, as each other civil work also.

Ehrbar & C. Tannò ETH Zurich , Switzerland H.-P. Vetsch Vetsch Rail Consult, Bützberg, Switzerland ABSTRACT: Since more than 30 years long tunnels with a total length of more than 50 kilometres exist. Many of them show a different tunnel system: double track tunnels with ser- vice tunnel, two single track tunnels and two single track tunnels with a service tunnel are the existing systems. The decision on the tunnel system of this long tunnels had to be taken at a time when only few information on operation and maintenance costs were available. Today more information on operation and maintenance should be available. The paper shows, how the decision-making process could be adapted today considering the criteria construction, operation and safety and life cycle. Recommendations on the selection of the tunnel system will be given, based on the available operation experience of the long tunnel railway tunnels. 1 MOTIVATION For more than 100 years railway tunnels with lengths of 10 km and more have been built. To a large extent, these tunnels are still operating today (see Table 1). However, the demands posed on such tunnel systems have increased during the past years. For a long-time, the double track Tunnel without a service tunnel was the most popular system (variant 1A). Due to the higher safety standards such a system, even with an additional service tunnel, is no longer permissible nowadays unless drastic operating restrictions for mixed railway traffic apply (Ehrbar et al., 2016).

  • Regional Economic Effects of Transport Infrastructure Expansions
    Regional economic effects of transport infrastructure expansions: Evidence from the Swiss highway network Stephan Fretz∗ and Christoph Gorgasyz April 2013 Preliminary { please do not quote without authors' permission. JEL Classification: H54, O18 Keywords: Infrastructure; Transportation; Regional Development; Synthetic Control Abstract Expansions of transport infrastructure networks may have substantial impacts on the development of regions. Observable regional economic effects do not necessarily reflect effi- ciency gains, however; they may also stem from redistribution across regions. In this paper, we propose that efficiency gains result from an improvement in the absolute accessibility of regions, whereas redistribution is caused by changes in their relative accessibility. We investigate this hypothesis based on expansions of the Swiss highway network. Using the synthetic control method developed in Abadie, Diamond and Hainmueller (2010), we an- alyze whether specific highway network expansions led to increases in regional income per capita. We find that effects vary strongly across the different cases. As expected, we observe the largest impact when both absolute and relative accessibility of a region increase. ∗University of St. Gallen, Switzerland.

  • Old Overhead Line Over the Gotthard Pass to Be Relocated to the New Road Tunnel Bundling of Infrastructures Frees up the Alpine Landscape
    Media release Swissgrid Media Service 2 June 2021 Bleichemattstrasse 31 P.O. Box 5001 Aarau Switzerland T +41 58 580 31 00 [email protected] www.swissgrid.ch Old overhead line over the Gotthard Pass to be relocated to the new road tunnel Bundling of infrastructures frees up the Alpine landscape The extra-high-voltage line over the Gotthard Pass is being relocated to a special service duct as part of the construction of the second road tunnel. The Swiss Federal Office of Energy (SFOE) has given Swissgrid confirmation that no sectoral plan procedure needs to be carried out for this project. Several agreements have been concluded with the Federal Roads Office (FEDRO) in connection with the service duct. Over the next few years, Swissgrid will prepare the cabling of the extra-high-voltage line on the Gotthard Pass between Airolo and Göschenen. Measuring around 18 kilometres in length, this will be the longest cabled extra-high-voltage line in Switzerland. In future, the Airolo – Mettlen 220 kV extra-high-voltage line will be laid underground in the Gotthard road tunnel between Airolo and Göschenen over a distance of approximately 18 kilometres. This is possible thanks to synergies created by the construction of the second Gotthard road tunnel by the Federal Roads Office (FEDRO). The cables of the line will be laid in a separate service duct (WELK HS) beneath the hard shoulder. The new line is expected to go live in 2028. The line between Airolo and Mettlen is a vital part of the north-south connection for the electricity supply in Switzerland and Europe.

    All roads lead to Ticino! ticino.ch/wege-ins-tessin The itinerary becomes part of the holiday: discover the best one for an exciting trip! “It’s marvelously rich and beautiful and there is everything, from the alpine landscapes to the Mediterranean ones” with these words the Nobel prize winner Hermann Hesse described Ticino, his adoptive homeland. Glaciers and palm trees, lakes and mountains, ancient churches and modern architecture, silent valleys and vibrating cities generate an harmonic ambiance. As various as Ticino’s attitudes are, as various are the ways to reach the region: it doesn’t matter whether you come by plane, car, train, bus, bicycle or on foot. Myriad of roads lead you to the sunny South of Switzerland: Ticino. Your journey begins only a stone’s throw away from you home. By train. Travelling by train in Switzerland is comfortable and very reliable; thanks to the world’s best rail system. Numerous international trains arrive in Ticino every hour from the gateways Basel und Zurich, stopping in Bellinzona, Lugano, Mendrisio and Locarno. The TILO-train offers connections within the main cities in Ticino every 20 minutes. By car. Ticino is easily accessible by car. The shortest way from the North to the South of the Alps is through the Gotthard road tunnel or the alpine pass. A modern and efficient motorway runs through all Ticino (A2). The Gotthard tunnel (17 kilometers) allows travellers to avoid climbing the majestic alpine passes. It is for 125 years that this tunnel has been linking the North with the South. By plane.

  • Gotthard Base Tunnel, Switzerland Experiences With
    GOTTHARD BASE TUNNEL, SWITZERLAND EXPERIENCES WITH DIFFERENT TUNNELLING METHODS Heinz Ehrbar1 Abstract – At the time when it is completed, the Gotthard Base Tunnel in Switzerland, with a total length of 57 km, will be the longest railway tunnel in the world. The complete tunnel system consists of 153.3 km of access tunnels, shafts, railway tunnels, connecting galleries and auxiliary structures. Excavation of the main system started in 2002. More than 108 km, or more than 70% of the full 153.3 km of tunnel system, had been completed by the end of March 2008. Conventional tunnelling as well as excavation by TBM have been used. The experience gained is sufficient to allow conclusions to be drawn regarding each method. Palavras-Chave – método de escavação em túneis 1 AlpTransit Gotthard Ltd.

Switzerland’s New Rail Link through the Alps (NRLA) will provide a faster and more reliable rail link between northern and southern Europe. It will enable much of the freight traffic to be shifted from road to rail. There are two NRLA lines: the Lötschberg axis (in operation since 2007) in the west, and the Gotthard axis in central Switzerland (to be completed by 2019). The 57-km-long Gotthard Base Tunnel is the main structure of the Gotthard axis.

  • Gotthard Base Tunnel - Mastering Surface Deformations in the Area of Two Concrete Arch Dams - Innovative Solutions
    Gotthard Base Tunnel - Mastering surface deformations in the area of two concrete arch dams - innovative solutions Ehrbar, H. 1, Bremen, R. 2, Otto, B. 3 1) AlpTransit Gotthard Ltd, Lucerne, Switzerland 2) Lombardi Ltd., Minusio, Switzerland 3) AXPO Ltd., Baden, Switzerland ABSTRACT The Gotthard Base Tunnel with a total length of 57 kilometres will be the longest railway tunnel of the world when the commercial operation starts in 2016. The tunnel system consists of two single-track tubes with an excavated diameter of 9.40 m. The excavation of the tunnel has been completed in March 2011. From 2005 to 2011 water saturated jointed rock masses close to two more than 100 m high concrete arch dams had to be excavated in the central Swiss Alps. The Nalps arch dam had to be passed by in a horizontal distance of 600 metres and the Santa Maria arch dam in a distance of 2 kilometres. The vertical distance in both cases was 1’400 metres. Tunnel excavation in water saturated jointed rock masses causes dewatering of the rock mass around the cavity. The dewatering effects on a large scale can cause measurable deformations at the surface even in the case of deep tunnels. Experiences with these effects have been made 1978 with the damage event of the Zeuzier arch dam in Switzerland and after the opening of the Gotthard road tunnel in 1980. In both cases deformations in the range of 10 centimetres and more have been observed at surface level several hundred meters above the tunnel axis. In the case of the Gotthard Base Tunnel a sophisticated topographical monitoring system allowed to observe the ground deformations since the earliest beginning of the tunnel excavation in the year 2002 throughout the whole year, also during strong winter times.
