In New Zealand, we don't call tunnels 'base tunnels', but the Rimutaka tunnel would meet the definition of a base tunnel:

Also I think the Kaimai tunnel would:

Both these tunnels pass more or less through the base of their respective mountain ranges.

Is it already known what bridges over Drau and Mur will look like on the Koralm Railway? (or this thread is only about tunnels?)

To my knowledge there will be no bridge over the Mur, but one Drau crossing:

I thought it would be more special. You're right, there will be no bridge over the Mur (I looked at the approximate map in the first post), but there should be two bridges over the Drau.

And that´s why the Koralm Tunnel schould be renamed into Koralm Base Tunnel in the first post of this thread.
Unfortunately I don´t know how to force KingNick to do that.

The 2nd bridge will be the "Jauntalbrücke".

The Koralmbahn will cross the Drau at the same place, where the current railway line St. Paul - Bleiburg (opened only in the 1960ies) now crosses the Drau.
Parts (at least the pylons) of the existing 420m long 95m high bridge will be also used for the Koralmbahn.

Photos of the existing Jauntal-bridge:

It should be added, that the main purpose of the Koralmbahn is not the improvement of the connection between Graz and Klagenfurt.

Together with the Semmering-tunnel it will form a new modern axis from Vienna to the South with shorter travel times from Vienna to Klagenfurt and Italy.

Of course it will be a big advantage also for Graz. Now Graz is basically a dead end in the railway network, as the line to Klagenfurt/Villach and Graz are splitting in Bruck/Mur.
In the future trains from Vienna to Klagenfurt/Villach and beyond to Italy will run via Graz. This will also improve the Vienna/Graz-connection (more trains).



Current and future travel times (with Koralm-line and Semmering-tunnel):

Wien Meidling - Klagenfurt:
current 3h51 (one train per day: 3h46)
future ~2h55 / ~2h30 (IC-service / accelerated express service with less stops)

Wien Meidling - Graz:
current 2h30
future ~2h00 / ~1h45

Graz - Klagenfurt:
future ~0h55 / ~0h45


Travel time Wien - Venezia could then be ~5h30, but that also depends on the train path in Italy.
The 5h30 is based on 2hrs from Tarvisio BV to Venezia Santa Lucia, which I calculated with current infrastructure data (according to the fasciciolo linea of RFI), 2 intermediate stops (Udine, Venezia Mestre) and a buffer of 10%.

As it is today the Italian railroad official do not seem very interested in border crossing trains. In fact they seem to do their outmost to ruin cross border passenger rail. I hope this is going to chance, the sooner the better.

Some more infos:

http://www.bmvit.gv.at/verkehr/eisen...bbt/index.html then Streckenpanung

For example, here http://www.bmvit.gv.at/verkehr/eisen...0118-02458.pdf (22 MB) the detailed path of the tunnel (note that the Pfitsch/Vizze access tunnel at km 39 will not be built, and the Mauls/Mules access tunnel modified to replace the Pfitsch one).

Something in Italian about the southern access to the BBT: http://www.ferroviabrennero.provinci...o_informativi/ (very very far in the future)

Some notes about the Italian section (I suggest to continue there, as the project is directly linked to the BBT and the Austrian works and as none of the projects along the Brenner axis would make sense alone, except the quadrupling of the Inntalbahn).

The base tunnel ends in Franzensfeste/Fortezza, from where the line would continue in a first phase to Waidbruck/Ponte Gardena, roughly this: https://maps.google.ch/maps?saddr=A2...sz=13&t=m&z=11 (it should open together with the BBT to reduce the ramp from 22 per mil to 12)

Another section would bypass Bozen/Bolzano: https://maps.google.ch/maps?saddr=A2...sz=12&t=m&z=12 (to reduce noise in the city and increase capacity in the city station and the flat junction of the line to Mals/Malles, note that between this and the previous section there is already a 13 km long, straight new tunnel built in the 1990s, so that there is little interest to duplicate it)

A third section would bypass Trento, but I doubt it will be built soon.

Then new tracks would fill the gaps between these new sections of line, but as this would mean 200 km (from the BBT to Verona) of new line nearly entirely in tunnel (as it is planned now), I sincerely doubt we will see it this century. I think the first section I described above will be built as without it the BBT looses a lot of its usefulness (this section will eliminate the need of bank engines pushing trains uphill), but I doubt the other sections will be built before 2050 (except maybe Bozen/Bolzano bypass, which is in a more advanced planning stage).

I have noticed that a lot of regional trains running on the Südbahn (near vienna) are using the ÖBB 1044/1144, however, 2-3 years ago they were run exclusively by 1016/1116 locomotives.
Can someone explain to me why that is? Did they reassign the Taurus locs to the railjet program?

Germany wasn't able to come up with any plans so far. Much talking, no action at all.

It's even worse than for the Gotthard northern access lines...

********

By the way, is there a link that shows how much has been bored, as is the case for AlpTransit?
