Yes, but extend the line to Altdorf, and then somehow to Stans or Luzern along the Vierstattersee. Then they should build the old plan for a 3 track line form Interlaken via Spiez to Zweisimmen. Then you can have the Galcier meets Golden Pass express. From St. Moritz to Montreux, that would be fantastic.


And for the longest tunnel, if they ever decide to build the north extension for the Gotthard, it's pretty easy to extend the lenght with more then 10 km.

I always thought it would be great to have the Brünig line connected to the Monteux-Zweisimmen line.

From Altdorf to Stans could be hard, but it could get over the Seelisberg, with a cogwheel section, would shurely be a scenic track.

You can do Switserland on a low budget, just don't do anything expensive! (Yes, best travel tip ever!)

I like to go through the tunnel too, but it won't be as impressive as the old line.

A while back China was talking about digging a tunnel from Taiwan to the mainland, a distance which at its narrowest point is roughly 125km. Whether it happens remains to be seen, but I think as the train to Lhasa proves, if they have the technology, very little else stands in their way.

Press release of 06.09.2006
Milestone in the Gotthard Base Tunnel – First Breakthrough by a Tunnel Boring Machine

The first tunnel boring machine (TBM) in the Gotthard Base Tunnel started out in the east tunnel from Bodio in November 2002. Two months later, the second TBM started driving in the west tunnel. A number of different geological zones had to be overcome along the approximately 15 km route to the multifunction station at Faido. The highly diverse geology impaired driving progress. Modifications to both TBMs brought sharp improvements. In December 2005, with 38 metres, the TBM in the east tunnel attained the highest daily advance rate of any TBM in the Gotthard Base Tunnel to date.
Today's breakthrough at Faido took place with the expected precision. With a tunnel diameter of just under 10 metres, the deviation per 100 metres of tunnel length must not exceed 1.5 millimetres. Continuous measurements showed that the specified accuracy was maintained along the entire length of the drive. At breakthrough, the deviation of the TBM was only 2 cm vertically and 5 cm horizontally.
More than 1000 guests attended the breakthrough celebration in the multifunction station and watched as tunnellers from Bodio and Faido shook hands. In his celebratory speech, Peter Zbinden, CEO of AlpTransit Gotthard Ltd, praised the precision and quality of the work, and thanked the TAT Consortium, the GBT South Engineering Consortium, and the approximately 1000 tunnellers and engineers from Faido and Bodio for their achievement.
A Construction Site Open Day will be held at Faido on Saturday, September 16, 2006, from 9 am to 6 pm. Members of the public will have a unique opportunity to see the cutting head of the TBM.

Press release of 16.09.2006

New visitor record at AlpTransit construction site open day in Faido

Record at the AlpTransit Gotthard construction site open day in Faido: On Saturday, September 16, 2006, almost 6,000 visitors took the opportunity to view the gigantic cutting head of the tunnel boring machine and to inform themselves about construction of the world's longest railway tunnel.

The rush already started in the early hours of the morning: Nearly 6,000 people from all over Switzerland and the Lombardy region of Italy visited the construction site at Faido. The date was deliberately set soon after the breakthrough on September 6, 2006, so that visitors would have the opportunity of marvelling at the huge cutting head of the tunnel boring machine. Access to the multifunction station at Faido was provided by shuttle buses which transported the visitors through the 3 km long access tunnel under the mountains. The visitors were interested to receive from the engineers and project team members who were present knowledgeable explanations about the machines being used for the construction process.

Saturday's event was the only Construction Site Open day being held by AlpTransit Gotthard Ltd on the entire Gotthard axis this year.









Press release of 09.10.2006

More than 100 Kilometres Cut Through the Gotthard

Early this morning the second tunnel boring machine in the Amsteg section also reached its destination – about half a year earlier than planned. Since January 2004, Gabi II has cut 10,700 metres of the west tunnel. Of the total length of the Gotthard tunnel system of more than 153 km, 100 km have now already been excavated.
At 3.37 this morning, the tunnellers in the Amsteg section of the Gotthard Base Tunnel could finally complete driving with the Gabi II tunnel boring machine (TBM). This is approximately half a year ahead of schedule. Between when it started cutting in January 2004 and today, the machine has cut 10,700 metres in the west tunnel. Only about 185 more metres remain to be excavated before the boundary to the Sedrun section is reached. For technical reasons which were planned, this remaining distance will not be cut with the TBM but by drilling and blasting. This work will start in the new year and last until summer 2007.
The Gabi II TBM will be dismantled underground by February 2007 and the individual parts transported out of the tunnel on the construction railway.
After cutting the same distance of 10,700 metres in the east tunnel of the Amsteg section, the Gabi I TBM already reached the end of the mechanically driven length of the Amsteg section at the start of June 2006. Dismantling of this machine is already at an advanced stage.
Driving on the other sections of the Gotthard Base Tunnel is also progressing well. A few days ago the total distance cut reached 100 km. This means that of the total length of the Gotthard Base Tunnel of more than 153 km, approximately two thirds have now already been excavated.





Press release of 26.10.2006

Gotthard Base Tunnel: Second tunnel boring machine arrives in Faido

After driving some 13.5 km – three years and eight months after starting out from Bodio – the second tunnel boring machine reached the multifunction station at Faido. The breakthrough took place in the afternoon with a deviation of only a few centimetres.
The second tunnel boring machine (TBM) started out in the west tunnel of the Gotthard Base Tunnel from Bodio in February 2003. A number of different difficult geological zones were overcome along the approximately 15 km route to the multifunction station at Faido. Technical modifications to the TBMs in both the east and west tunnels enabled the advance rate to be improved. In December 2005, with 38 metres, the TBM in the east tunnel attained the highest daily advance rate of any TBM in the Gotthard Base Tunnel to date.
Today's second breakthrough at Faido took place with the expected precision. With a tunnel diameter of approximately 10 metres, the deviation was only a few centimetres.
With the arrival of the second TBM in the Faido multifunction station today, mechanical driving in the Gotthard Base Tunnel is currently at a stop. Both of the machines in the south will be overhauled and transported through the Faido multifunction station. In about six months time, they will resume driving in the direction of Sedrun. As planned, the cutting heads of both machines will be enlarged by 60 cm, because in view of the greater depth of rock and the consequently higher rock pressure between Faido and Sedrun, the tunnels will be cut with a diameter of 9.40 metres.
The two tunnel boring machines between Amsteg and the boundary of the Sedrun section have also reached their destination six months and nine months ahead of schedule respectively. The TBMs will be dismantled underground and the individual parts transported out of the tunnel on the construction railway.
Driving on the other sections of the Gotthard Base Tunnel is also progressing well. The 100 km mark has already been passed. This means that of the total length of the Gotthard Base Tunnel of more than 153 km, more than two thirds have now been excavated.

I check out your thread occasionally but usually I check the tunnels site.

Keep it only a couple of years to go until completion.

I only go to the tunnel site after I see one of your updates. I appreciate the reminders on this fascinating project - thank you. Please keep posting when there's news.

I should indeed post more in this topic.

The total costs of all the Neat projects are now projected to be 24 Billion SFr. That will probably even be higher as the total construction of the Gotthard and Ceneri Base tunnels will take atleast another 10 years.

The TBM are being revised and transported to the other side of Faido station, where they will be used to excavate other (about) 12 km of tunnel.
