Hmm, ok I haven't met any person in my life that found the railjet comfortable . And I've to use it often for ~7 hours from Vorarlberg to Vienna (and sometimes even further to Budapest). Afterwards my back hurts all the time! Luckily there's at least a fast night train with comfortable compartment coaches!

Tilting is currently - as far as I know - also disabled in Germany. It will be enabled again, but they have to deal with some technical things before.

I think tilting was active also in Austria, but the traisn didn't run faster (which is the basic idea of tilting), as the infrastructure was not suitable for higher speeds. So the tilting was just for comfort reasons (less lateral acceleration).

Austrian ICE network:

This map is wrong....

There is only 1 ICE-line to Austria (Frankfurt - Passau + Wien), plus there are some single ICE-trains from Germany to Innsbruck via Kufstein as well as via Mittenwald. But these are single trains, not what I would call a line (IMO a train line has to offer regular intervals and at least 2-3 daily trains per direction).

No ICE-trains are running between Vienna and Muncih nor between Vienna and Bregenz.

Frankfurt via Passau to Vienna
Munich via Salzburg to Vienna

And Dortmund via Passau to Vienna (ICE 22). Hence, the map is wrong in not showing Hamburg.

Vienna - Bregenz was an Austrian ICE line untill 2010 and is now (fully?) replaced by Railjets. So is Vienna-Munich.

Today was the groundbreaking ceremony for the 27,3 km Semmering Basetunnel that will reduce travel time between Vienna and Graz around 30 Minutes. It's part of the so called "Baltic-Adriatic Corridor".

Großkoalitionäre Eintracht von Steiermarks Landeshauptmann Franz Voves und seinem niederösterreichischen Pendant Erwin Pröll. Opposition wettert gegen "Kuhhandel"
Gloggnitz - Zwei Tunnelröhren von 27,3 Kilometern Länge, zwölf Jahre Bauzeit (bis 2024), 3,1 Milliarden Euro Kosten: Das sind die Eckdaten des Semmering-Basistunnels (SBT), für den am Mittwoch beim künftigen Nordportal in Gloggnitz/NÖ der Spatenstich erfolgt ist. Die neue Südbahn, Teil des transeuropäischen Verkehrsnetzes, wird die Fahrzeit Wien - Graz um ein Drittel verkürzen und den Zuwachs im Güterverkehr bedienen, gleichzeitig bleibt das Unesco-Weltkulturerbe Ghega-Bahn über den Semmering erhalten.

Why is the planned tunnel curving so much? Drastically easier geology?

Gloggnitz (northern portal) is at 439 m asl, Mürzzuschlag (southern portal) is at 679, so it will be so curvy and long to reduce the maximum slope to 8 per mil (1 in 125).

Current tracks look hideous assuming the curves are up-to-scale.

Many parts just 60 or 50 km/h.
Smallest curve radius is just 190m....


A more detailed map of the current line (1:200.000 map):

How come Austria, no poor country, hasn't upgraded this important sector of their network ever since???

Two reason:

1) For political reasons the tunnel has to hit daylight again before the town of "Mürzzuschlag" and the track would be to steep for heavy freight trains if going straight.

2) To avoid rock layers containing lots of water.

Actually this is the so called "Semmering Basistunnel neu", so there have been plans for a different tunnel 30 years before. They actually already started drilling sounding boreholes in 1994, but had to face major water inlets to cause the whole tunnel being flooded. After that the very powerful Prime Minister of the federal state of Lower Austria, Erwin Pröll, was blocking the whole project for legal and political reasons.

It took 10 more years to come up with new plans, which also pleased "Pröllusconi" and another 6 years to finally start digging again.

Another factor, why it took so long was the ÖBB itself. They completely focused on their power horse, the Westbahn, and did not care that much for other railways. But now there's the political will to make the Südbahn just as good as the Westbahn starting with the Brenner Base Tunnel and the Koralmbahn connecting Graz and Klagenfurt.

The new track does not look very intelligent to me, it makes a large detour. Compare with the road there, the road makes a much more direct path. The green one looked much better.

That explains why the green route is not viable ... water flooding and all.

But not why something along the road route was not considered. The road seams quite streight, and has a small tunnel. Even if the speed would be slower, it might end up with the same time as a large detour would be avoided.

It's not just flooding. A straighter route would have a steeper grade, which would have been problematic for freight trains.

That's the reason, yes, cause now they need extra locos for freight trains. Operational wise very complicated.
