Sorry, but I don't know. What is the cause of the delay, and what is the problem with the route, if you don't mind?

State Governor Erwin Pröll. He prevented this project from materialising with some made up environmental concernes for many years.

some of the BBT and brenner axis - north connection Austria/Germany:
http://brennernordzulauf.eu/sites/de...legungen_0.pdf

for the Austrian share the border region, the medium green option is the realistic one, tunnel Kufstein south - Oberaudorf north (to the orange option south end), the other both are from human and nature and cost calculations non realistic

total area, the mentioned green, followed from the orange one (paralell to motorway A93) and for Rosenheim bypass is the direct line of the blue ones the most likely option (following the road bypass B15 west tangent)
(purple ones are austrian dreams but non realistic, yellow makes no sence in general to bring impact to non impact regions and expensiver than the blue ones)

ÖBB uploaded a new project movie about the Semmering Base Tunnel with English subtitles earlier today:

Just curious... but wouldn't it make sense for the Austrians to go alone and build a straight connection Wörgl-Salzburg (ca. 70 km) with a tunnel all the way through Deutsches Eck and Germany to connect Tirol/Vorarlberg and the rest of the country?


From Salzburg Hbf counting I imagine a 3 kms of tunnel from Aiglhof through the built up area and below the airport in Salzburg, then a 20 km tunnel from A1/Walserberg in Salzburg to Lofer in Tirol, built and maintained by the Austrians. No stops or anything on the German side at all needed (possibly not even a ventilation nor emergency shaft if that can be arranged to the Austrian sides of the border - The railway would stretch for 10-12 kms through German territory). From Lofer to St Johann it is already a quite wide and flat valley with several degrees of freedom for tunneling depending on solution (as short or as long tunnels could be built as needed), from St Johann to Wörgl there would be one 7-15 kms of a tunnel before connecting to current Inntalbahn near Wörgl if the railway follows the road B178 closely.


The benefits would be immense for Austrian railway traffic. The Austrians get a new 250 km/h railway connecting east and west. The current route between Salzburg-Innsbruck (going through Rosenhem in Germany) would be shorted by 55-60 kms and to top it up the railway line Munich-Verona would open up for more capacity. It would also let the current Salzburg-Tirol railway line get a shortcut between Wörgl-St Johann (Kitzbühel might not be happy about it as it'll be bypassed by this, but I am sure some satisfying solution for the traffic can get worked out). Imagine going 130 kms between Innsbruck-Salzburg in just 35-40 mins instead of 105-110 mins.


Of course a better railway between Wörgl-Munich is still needed. I was just thinking of this railway line as the next base tunnel/Koralmbahn-project for the Austrians. Would Germany have any reason to object this proposal?

We might build that at the day money starts growing on trees.

Well yes there are some other projects for the next 10 years up and running, such as these base tunnels that are being built and referred to here.


But if we wish the project to start, in say the year 2030, once all these base tunnels have been completed planning for this should start now. Not at least there has to be negotiations with the Germans for the passage through Deutsches Eck. My hope is that a project which undertunnels the country and doesn't affect it in any other way in its 10-12 km passage of the country could skip the usual German planning process, or at least would limit reviews to only such technical areas like projected changes in water flows etc. A German "Planfeststellungsverfahren" is a true nightmare in every bureaucratic sense of the word.

Status update for the Koralmtunnel:

The southern tube will be completely excavated by the end of this year. The miners are only 3 km apart. The northern tube has 10 km to go.

Still, it's a very impressive project that I look forward to hearing more about as it's built.

Brenner Basis Tunnel (BBT), Contract Mules 2-3, Italian Section, Bolzano (BO)

There is progress now (2018) with the Brenner Base Tunnel on the Italian side. The Tunnel Boring Machines (TBM) are just beginning their main tunneling runs from near Bolzano towards ending up at the Austro-Italian border and are the first on the main project to use construction railways with tunnel locomotives for supplying lining materials of segment ring sets, pea gravel for grouting, conditioning chemicals and man-riding. The contract for TBMs for boring the main project twin running tunnels on the Austrian side down to the Austro-Italian border has not yet been awarded, so a good prospect of also having tunnel locomotives here.

For the Italian side Contract Mules 2-3, two different sizes of TBMs are used for each of the main running tunnels and for the exploratory tunnel, the contractor Astaldi/Ghella will be using tunnel locomotives supplied by the German builder SCHÖMA Christoph Schöttler Maschinenfabrik GmbH, 49356 Diepholz. There will be the smaller locomotive of Model Type CHL60G for use in the exploratory tunnel and the larger main running tunnels will serviced by the heavy duty Model Type CFL200DCL. Of the consortium partners, Ghella will operate the TBM in the Eastern running tunnel and Astaldi will operate the TBM in the Western running tunnel. There will be as many as circa 20~30 locomotive units supplied over the next two years.
Brenner Basis Tunnel (BBT), Exploratory and Service Tunnel, Contract Mules 2-3, Italian Section - Astaldi/Ghella/Pietro/Cogeis/PAC jv (C) - Herrenknecht TBM DoubleShield Rock S-1054 6.82 m od x 14 900 m (12/16~_/21)

Brenner Basis Tunnel (BBT), Main Running Tunnel, Contract Mules 2-3, Italian Section - Astaldi/Ghella/Pietro/Cogeis/PAC jv (C) - Herrenknecht TBM DoubleShield Rock S-1071 "Flavia" [Ghella] 10.6 m od x 19 900 m (_/18~_/22)

Brenner Basis Tunnel (BBT), Main Running Tunnel, Contract Mules 2-3, Italian Section - Astaldi/Ghella/Pietro/Cogeis/PAC jv (C) - Herrenknecht TBM DoubleShield Rock S-1072 "" [Astaldi] 10.6 m od x 19 900 m (_/18~_/22)
To understand the Italian sections there is a good diagram located here:
