Yesterday the first track of the Pollegio bypass, part of the junction between the old and new line, has been opened. The other track will follow next Monday. Until then one track of the old line will be used by work trains to dismantle the line itself (that's why only one track has been opened at the moment).

Below a video taken today:



And now the other junction south of the tunnel:



That's how the line through the village of Pollegio looked like:

When are the tests in the west bore of the Bodio-Faido scheduled to start? Was it next spring?

In a judgment of 9 July 2012, the Lombardy Regional Administrative Court accepted appeal No 1359 of 2011 and annulled Resolution No 33 of 13 May 2010 by the CIPE (Interministerial Economic Planning Committee) on the grounds that the technical committee that had assessed the environmental impact of the project had taken no account of the fact that the quadrupling of the railway line had actually been ruled out at the preliminary planning stage, as it had been deemed to have an excessive impact on local urban surroundings; the committee itself had apodictically affirmed that the impact in terms of vibration and noise would be neutralised by the mitigation measures included in the final project. The committee thus expressed opinions that would have called for further, more appropriate research and essentially anticipated the assessments that should have been made under the new environmental impact assessment procedure.
This is not just nimbys....

Are delays expected due to the bankruptcy of Alpine Bau?

hi, coccodrillo
what is exactly "lined"?
is that a layer of concrete that cover inside the tunnel?

The lining is the material posed on the walls and the ceiling that cover the rock.

It can be poured concrete like this: http://i42.************/5u0h9c.jpg

Or sprayed concrete: http://www.hightech.fi/direct.aspx?a...0&prm2=article

But the lining can also be made by bricks (usually in older tunnels, built up to around 1940), or be absent: where the rock is extremely strong and there are no needs to have an "aerodynamic" tunnel there is no lining at all, and you see the rock going through the tunnel.

What exactly are we looking at in these last five photos?

Excellent quality, by the way.

It is the old line near Pollegio being demolished, replaced by the new AlpTransit line including a junction.

See post #754 for the old line (third video) and the new one with the junction (first video).

Thanks. What's the plan for the old right of way? I assume it will be turned over to the village for general development, right?

I heard that a road for local traffic, walkers and bicycles with some kind of park amenities (trees, benches, etc) will be built. However the village of Pollegio has only 700 inhabitants, so nothing spectacular will happen! If it wasn't for the need of AlpTransit, the railway would have remained where it had always been. Even if it wasn't necessary to divert the old railway to connect it with the new one, I suppose it had been done because not moving the old railway would have meant building noise walls along both the new and old lines, so that basically it would have costed more or less the same.

See the map: https://maps.google.ch/maps?q=Polleg...o,+Ticino&z=17

I doubt, because civil works are nearly completed in the Gotthard BT (boring already ended in 2011), while as far I know Alpine is not involved at all in the Ceneri BT.

Southern CBT portal, 19.07.2013.

[IMG]http://i43.************/egu14y.jpg[/IMG]

Tracks, rolling stock and other machines of the construction sites are up for sale (seriously). Here is a driving trailer for passengers.

[IMG]http://i44.************/fyoa40.jpg[/IMG]

There is a complete railway here. The last narrow gauge work train ran not much time ago, likely between 10th and 15th July 2013. Here are flat wagons and tracks, considering that there were two narrow gauge tracks in each single track running tunnel, there might have been over 200 km of 900 mm gauge tracks, although not all in service at the same time. It is also likely that the Erstfeld (northern work site) and Bodio-Pollegio (southern) narrow gauge networks were never linked together. No narrow gauge trains have been used for the CBT, although half a dozen vehicles have been used for a nearby road tunnel built at the same time (a project urnelated to the CBT).

[IMG]http://i42.************/2z827mw.jpg[/IMG]

Bonus: noise barrier protecting some trees near the southern CBT portal. Because of a too much strict law, they ruined the landscape building high noise walls even where freight trains will become a thing of the past, like on the old Gotthard and Ceneri lines.

Hi Coccodrillo
I'am really intrigued by the track machinery, just wondering if you have photos or video of the machine in operation
Regards

Hi, if you look back a number of pages in this thread, there are some great pics of the tunnel and some of the machines used to build it.

There are certainly videos of track machines on YouTube, but myself I have never seen them in operation. I just have some photos of them taken during the Sunday/evening pause, and they are all above.

Thanks Coccodrillo, yes I have found many machines on Youtube but none quite like your photos. I was curious if they cut and pick up an entire track section at a time or if they are dismantled first.

Love the photos, please keep them coming as I am bit far away to see them for myself, hopefully Caio

Looking at the photos, I suppose that the two blue things are cranes that run on the top of the wagons, picking up entire sections of track (rails and sleepers), but I'm not sure.

However, in the last photo you can see some completed sections of new track, so that's possible. I have also seen piles of completed tracks on another section of line near the CBT, temporarily removed and put one above the other to allow working on the trackbed.
