Ceneri Base Tunnel - Articles and news items
Issue 4 2015 / 6 August 2015 /
The NRLA Gotthard Axis comprises of the Gotthard Base Tunnel and the 15km-long Ceneri Base Tunnel. The two single-track tubes of the Ceneri Base Tunnel are complemented by branch-off structures to allow additional traffic connections. So that the ambitious time schedule can be met despite difficult geological conditions, work on lining the tunnel is proceeding in parallel with driving. Marco Ceriani, Chief Construction Officer of AlpTransit Gotthard Ltd, gives further construction status details…

Work on the Gotthard and Ceneri base tunnels is on course. In the Gotthard Base Tunnel between Erstfeld and Sedrun, the ballastless railway track has been laid in both tubes. In total, 45% of the railway infrastructure systems have been installed. A pilot operation between Faido and the south portal at Bodio will start on schedule in December 2013 – a further important milestone on the way to the world’s longest railway tunnel becoming operational in 2016. Also, more than 60% of the Ceneri Base Tunnel has now been excavated. AlpTransit Gotthard Ltd is confident that the Ceneri Base Tunnel will be ready for operation with scheduled train services in 2019.
Gotthard Base Tunnel: status
Overground section Altdorf–Rynächt
The environment between Altdorf and Erstfeld has changed during the last year. Work on the built structures along the overground section is complete. In August 2012, the Riedstrasse underpass was completed, and in September 2012 the Wysshus underpass and both roundabouts were completed.

Throughout 2012, SBB Infrastructure is undertaking a number of construction projects across Switzerland: in the two largest Swiss cities, Zurich and Geneva, in the St. Gallen and Schaffhausen conurbations, in the canton of Ticino, in the Alps, and even beyond Switzerland’s borders. This article presents an overview of the major ongoing construction projects, describing the progress achieved so far and what work still lies ahead.
The Swiss Federal Railways (SBB) network is the world’s busiest rail network, carrying approxi – mately 9,800 trains every day to all parts of Switzerland and, not surprisingly, the network is edging ever closer to its capacity limits. Zurich’s main station – serving almost 400,000 passengers a day, and thus by far the busiest station in Switzerland – is already a major bottleneck, while capacity expansion in other parts of Switzerland is also urgently needed. SBB Infrastructure is responsible for operating, maintaining, expanding and renewing SBB’s rail network. With the exception of the Gotthard Base Tunnel, SBB Infrastructure is in charge of all major railway upgrades in Switzerland. Projects demanding a wide range of construction techniques are underway all across Switzerland, and some even extend into neighbouring countries. The largest, most important and most spectacular of SBB Infrastructure’s current expansion projects1 include the following:

Since the second final breakthrough on 23 March 2011, fitting-out of the Gotthard Base Tunnel has made rapid progress, and since September 2011, installation of the railway systems has been taking place from the north. Elsewhere in the Ceneri Base Tunnel, work has begun on the main drives from the intermediate heading at Sigirino. The inward drives from both portals have already been completed.
Status of work on the Gotthard Base Tunnel: Installation of the railway infrastructure systems from the north is progressing rapidly and the ballastless track is currently being laid from Erstfeld.
Altdorf/Rynächt–Uri: Along the overground approach line to the Gotthard Base Tunnel, various constructions such as underpasses, bridges, passages and retaining walls are being built. This work is already at an advanced stage.
In the autumn of 2010, work began on the northern railway installations site at Erstfeld. The site occupies approximately 65,000m2 and large halls, workshops and offices have been erected as the logistical base for installation.

On 23 March 2011, between Faido and Sedrun in Switzerland, miners excavated the last metres of rock of the Gotthard Base Tunnel. Both single-track tubes are therefore now continuously bored over their full length of 57 kilometres. In the Ceneri Base tunnel, the main drives from the Sigirino intermediate heading, as well as the inward drives from both portals, are in progress.
The Gotthard Base Tunnel
Since the second final breakthrough on 23 March 2011, the Gotthard Base Tunnel is completely cut. Lining work in the Erstfeld, Sedrun and Faido sections is progressing according to plan. At Bodio West, installation of the railway infrastructure for the test section is in progress.

The remarkable volume of tunnelling on a worldwide basis during the last two or three decades (see Figure 1) is not defined by the demands to improve the railway networks in many countries. Stimulation in this direction is especially given by the generally highly ranked socio-political requirement of improved mobility – both for persons and goods – achieving at the same time a better environmental balance.

Construction of the new Gotthard line with the Gotthard and Ceneri Base Tunnels is on course. In October 2010, a further milestone will be the final breakthrough of the Gotthard: the miners will excavate the last stretch of rock between the portals at Erstfeld and Bodio/Pollegio. On the Ceneri, in March 2010, driving towards the north and south began from the intermediate heading at Sigirino. Both construction projects have therefore taken a major step forward towards their respective scheduled openings in 2017 (Gotthard) and 2019 (Ceneri).

The year 2008 was highly successful for AlpTransit Gotthard Ltd. The work continues as scheduled and as things stand today, there is nothing to prevent the opening of the Gotthard Base Tunnel at the end of 2017 and the Ceneri Base Tunnel in 2019 as planned.
Overall mobility in Switzerland is forecast to grow by 15-30% between 2000 and 2030. Public transport is set to grow even faster, increasing its market share at the expense of car travel. For its part, SBB is forecasting an increase of 45% in passenger traffic in the same period. There are several contributory factors including general growth, changes in attitudes to mobility, developments in population and workplace patterns, the competitive effect of road traffic on rail, and not least a growing ecological awareness among broad strata of the population. If we are to cope with this growth, the continued expansion of rail services is essential.
