    Booked a trip yesterday, without knowing this has happened. ~1h off my usual trip time, which I got accustomed to in the last two decades. It's extremely awesome!

    Actually, the tunnel itself was only 17 years:

    1998: Start of construction of the Koralm Railway

    2008: Start of construction of the Koralm Tunnel

    2018: Breakthrough Koralm Tunnel

    2020: Final Koralm tunnel breakthrough

    2025: This announcement (https://orf.at/stories/3414173/ in German)

      Given the terrain and the amount of tunneling needed, completing such a project in 17 years isn't that bad.

      Seems software neckbeards on HN are equally as guilty of underestimating the difficulty of other people's work like the managers they complain about.

    Just yesterday B1M published an interesting video about the future longest tunnel between Lyon, France and Turin, Italy. It will be more than 50km, deeply below the Alps. The project has finally secured funding, from both countries and EU, and is on track.

        Isn't Italy a little geologically unstable?

        I'd be a bit nervous, going through a long tunnel, in a region known for vulcanism and earthquakes.

        • whizzter 21 minutes ago
          Italy isn't a puny country, it's over 1000kms between Sicily and the Alps (Like LA to Albuquerque), seems the fault lines reaches northern Italy (about 100km from the alps) but the amount of larger quakes seems smaller there.
        • AnimalMuppet 51 minutes ago
          It is unstable, but (I think) more so in the south. I'm not sure that the Alps region is unstable.

      It would be brilliant. Currently the Paris-Milan train line is barely competitive with flying between the two; knocking off 2-3 hours from the trip would make it around 4 hours in total, which is very competitive with flying (1h30 flight, but both CDG and Malpensa are big airports far outside the city, with significant time wasted getting to them, through security, etc). And of course it would be massive for Lyon - Turin, and Lyon - Milan too, where flying wouldn't even make sense any more.

    Its sister tunnel - the Semmering Base Tunnel [0] - is scheduled to be completed in 2030. These two combined greatly reduce the travel time from Vienna to Graz and Klagenfurt (combined 1h 15m time saving).

    You don't hear that much about great engineering projects today, yet it's still an incredible feat to build those.

    Interstate 70 in Colorado is very problematic. It is constantly backed up. Colorado needs to learn from this and get serious about rail for shipping and for human travel.

    Austria is the only European country I've been to that doesn't have cheap affordable intercity buses. Seemingly none at all. It was kind of strange... Does anyone know why?

    The only options to get around was the expensive train system - and anyone I asked was bewildered why I would want to take a bus.. Maybe next time I should look in to carpooling or some other options. How do low income people get around typically? I need to go to attend a conference, but it's not cheap coming from Asia

    EDIT: Seems I was wrong! Sorry. There are buses, (maybe fewer than other countries?)

      >Does anyone know why?

      Small county with small market monopolized by few politically connected local players in every major sector of the economy who sometimes enjoy regulatory protectionism from the government to keep foreign competitors out and turn a blind eye on racketeering practices.

      That's how everything, including stuff made in Austria is more expensive than the same stuff sold in Germany even though wages are lower.

      Same issues like in other small markets like New Zeeland except Austria being an EU member should have more pressure from free trade competition but that doesn't always work in favor of the consumers.

      Flixbus definitely exists in Austria, but people generally take the train, which is much faster and more comfortable.

      There are various discount membership plans available that sometimes pay for themselves after just one round-trip or even one-way ride, and on the most popular connections there's now a private operator competing with the state-owned railway.

      A yearly flat-rate ticket for intercity trains is also relatively affordable for EUR 1400 per year.

        >Flixbus definitely exists in Austria, but people generally take the train, which is much faster and more comfortable.

        Not always true. The Graz-Vienna(Airport) trip is often quicker by flixbus than by OBB train.

        Trains in Austria are quite slow , often travelling at the same speed as cars on the highway or often times even slower.

      • contrarian1234 1 hour ago
        Oh really? I took the Flixbus from the Czech Republic and is stopped near the border and then after that it was train only. Maybe I ended up in a weird spot then! I just checked and there are indeed buses in-country. Strange that I somehow couldn't find any then

        Thank you for the info!

        • lxgr 1 hour ago
          There's definitely bus service (not just Flixbus, also Regiojet and probably others) between Vienna and Prague.
    • b0vinat-- 1 hour ago
      That part of Europe has historically loved its trains. The train is more than transportation there. It’s an institution and part of the culture. Have you been to a toy store and looked at the precision and cost of the train sets? They don’t just ride the train, the train is part of who they are and what they love, starting when they’re small children. The trains run on-time, they’re clean, and overall they tend to be more modern. In addition, people walk.
    • tomw1808 1 hour ago
      yes, we do, e.g. flixbus. and some others I think. Haven't been traveling for a while by bus around Austria. Apples/Oranges probably, but I do know vienna<->bratislava has like 3-4 different companies operating the same route with similar busses at similar times with different prices.

      And talking about apples/oranges, let me add apples/bananas: Vienna to Budapest by train cost a lot when booking via öbb. And not a lot when booking via Regiojet.

      The problem is the offers are all scattered around imho.

      • jack_tripper 42 minutes ago
        Yep, single tickets on Austrian ÖBB is not cheap at all without subscriptions or discounts.

        Prices are good only if you use it regularly as a commuter via a yearly subscription (Klimaticket), but for one off trips, prices are more expensive than flying.

    For those that can read German, here is a little article that explains some of the obstacles over time:

    First, this is a massive accomplishment. When I looked at the Wiki page: https://en.wikipedia.org/wiki/Koralm_Railway

    ... it looks like a multi-multi-multi-phase project. Hats off to making this work.

    Second, I noticed how long it took to build this tunnel: Koralm Tunnel -> https://en.wikipedia.org/wiki/Koralm_Tunnel

    It is 33km, and it took from 2008 to 2025 to build it. That is a damn long time! The Toei Oedo line in Tokyo is 40+km and was built in about 10 years. My guess about the wild difference: The geoengineering of the Koralm Tunnel is way more complex, and/or the rock is much harder. Can anyone with experience in this area comment? I would like to learn more. I guess that most of central Tokyo is aluvial plains (Shanghai is similar), so you are basically digging through clay and sand -- easy stuff for modern tunnel boring machines.

    • monster_truck 3 hours ago
      The rock they dug through for Koralm is, no hyperbole, about as bad as it gets. It's the gnarliest part of what's under the Alps and required them switching back and forth between boring and blasting.

      Being two separate tunnels, it also needs twice as much excavation work. It's also ~25x deeper than Toei Oedo (4000ft vs 157ft). At 4000ft the rock itself is 45-50C!

      • manarth 2 hours ago
        The Koralm tunnel has a different temperature gradient, as the depth is a consequence of a mountain on top of the tunnel, rather than an increased proximity to the earth crust/core.

            > "The undisturbed rock temperature varies from 10 °C, in tunnel sections close to the portals, to 32 °C in the tunnel centre"
        
        32°C is still a significant engineering concern, but not as consequential as 45–50°C.

        https://www.sciencedirect.com/science/article/pii/S088677982...

        • monster_truck 45 minutes ago
          Looks like they reported a peak of 39C in the summer. Either way I figured that would still be pretty miserable, especially if it gets up around 100% humidity.

          Assumed they would at least have their own air in the bits that didn't have aircon/ventilation while it was being built. They don't even need to do that anymore! The ventilation systems they used are as advanced and bespoke as the boring machines.

          Because they were blasting too, they couldn't utilize full-face pressurization of the entire tunnel to maintain negative pressure to suck all of the fumes, dust, silicates, etc out like they would if it was only boring. That's 1-3kPa, "leaks are jets of air, can pull an airlock door closed hard enough to break bones" territory.

          Instead, they have a bunch of dedicated supply and exhaust vents going to the surface (some up to 2m in diameter) and sets of connections between the two tunnels with huge axial fans. It allows them to selectively apply "slight" negative pressure to any of the individual segments when they need to clear them. 50Pa is ~10x what you encounter in a negative pressure highrise. It is described as a "constant slight breeze"

          I found this short video on some of the safety features of the finished tunnel. It almost looks "too serious", like something out of a James Bond movie https://www.youtube.com/watch?v=I8trt96huf0

      • sweezyjeezy 1 hour ago
        It's also really hard to make the tunnel remain a tunnel over its expected 150 year lifespan - given that it basically runs through a fault line. They had to study and test local geology for about 15 years, build certain sections to expect some movement over time, as well as kit everything out with a lot of sensors.

        Overall an amazing achievement, and unsurprising it took this long to figure out!

        • monster_truck 39 minutes ago
          After seeing some of the safety features in a short video I linked in another comment, I get the impression that this is either going to last much longer than 150 years or something so catastrophic will happen that nothing that could have been built would've persisted.
      • throwaway2037 2 hours ago
        Good point about "boring vs blasting". I didn't think about that. I remember reading about the longest tunnel in Japan between Honshu and Hokkaido (Seikan Tunnel). I recall that it was entirely hand drilled due to unusual soil conditions. I wonder if that would still be true today with state of the art tunnel boring machines.

           > Being two separate tunnels, it also needs twice as much excavation work.
        
        Yet another great point. At some of the Toei Oedo stations, you can see a miniature model of the weird overlapping twin tunnel boring machines. So, in theory it is two tunnels, but in practice, it was dug as a single, weird overlapping twin tunnel.
    • DoktorL 1 hour ago
      You also cannot directly compare a metro line to intercity rail. That line in Tokyo was like what, 20th they built all in the same terrain, they are really good at this by now. Meanwhile, rail tunnels are usually bespoke projects.
    • nasmorn 3 hours ago
      It is very strange that countries like Austria, Japan or Switzerland have some of the best rail systems in the world even though their bridge and tunnel requirements are huge. In the US building rail on any terrain seems to be more expensive than basically anything one can build in Austria.
      • kaon_2 3 hours ago
        Not strange at all! If you want to go by car you must build even more tunnels. Mountainous regions favor rail just like urban areas do. Furthermore, 19th century investments into rail still pay off in mountainous regions, because once you build a railway bridge or tunnel, you are kind of dumb not to use it. In the USA competition from trucks or cars is much tougher.
        • bluGill 1 hour ago
          Note the US has the number one freight rail system in the world by most measures (there are lots of ways to measure this depending on how you want to abuse the statistics). Some of this is Europe has better river routes to work with (I don't know Asia), but some of this is Europe has focused more on passengers to the point where freight is unable to get through forcing trucks.
          • browningstreet 10 minutes ago
            And still, to drive on highways in the US is to drive between trucks.

        Here is a huge/difficult island with only 55K that has tons of tunnels: https://maps.app.goo.gl/abcnXtRNs9QdVkhC8

        Population size, density, terrain, etc. have nothing to do with it.

      Geography I guess[1].

      Kanto is flat, it's the only region in Japan that could sustain feeding such a massive population and could allow building the first mega city on the planet.

      Combine that with the massive engineering and rail experience Japanese have, and it's no surprise imho that combined with favorable geography they could build it quickly.

          The Japanese islands are situated in one of the most geologically active regions on Earth, primarily characterized by multiple subduction zones where four major tectonic plates, producing 'new' Earth, emerge.

      Is there any design? It's just the flag and a title + subtitle.

      Also, the EU is the most efficient government in terms of overhead, and having seen some of it up close not wasting time or money on "unifying design languages" for every single funding billboard is very much EU style. Just copy-paste by some local authority in Powerpoint in most cases, I bet.

      • wongarsu 3 hours ago
        Looking at the modern iterations of the program guidelines for these programs, especially [1] and [2], you basically have to use the flag, the text over, under or to either side of the flag (your choice) in one of 6 fonts (Arial, Auto, Calibri, Garamond, Tahoma, Trebuchet, Ubuntu or Verdana), and have some rules for minimum distance, minimum size and proportionality. They absolutely could have made those two match visually. But each program offers premade banners that match the design criteria, and those don't always harmonize. As you say, nobody cared

          That's simply not true, the EU subsidy budget is dwarfed by each country's national budget. From https://eubudget.europarl.europa.eu/en/how-it-works/ :

          The EU budget [..] accounts annually for around 1% of the EU's GNI (gross national income), or around €160-180 billion. National public spending by EU countries averages nearly 50% of their respective GNI.

          I mean, see Brexit; there's a bit of a "what have the Romans ever done for us" aspect to a lot of euroscepticism. Some of the more Brexit-y regions were also amongst the poorest, and thus the largest beneficiaries of EU funding (eg https://www.theguardian.com/uk-news/2016/jun/26/cornwall-fea...)

          The idea is to show people the benefits of the EU, essentially. It is unclear how well it works.

          Cornwall, say, had reason to feel hard done by; it was the second-poorest NUTS 3 region in Northern Europe. It's just that they were directing their ire at Europe, and not at the national government where it belonged. All but one of the ten poorest NUTS 3 regions in Northern Europe were in the UK pre-Brexit (along with the very richest NUTS 3 region, inner London), and there's a reason for that.

          (Of course, the problem is now solved by Brexit; as the UK no longer participates in Eurostat, _none_ of the poorest regions in the Eurostat statistics are in the UK!)

          • mytailorisrich 1 hour ago
            Yes, I remember Wales received a lot of EU funding for infrastructure and there used to be those "funded by the EU" signs everywhere. They voted in favour of Brexit.

            I think this sort of things does little to convince people. The road network was there and working before the EU, it is still there and working now.

            Especially, people were well aware that the UK was a consistent net contributor to the EU budget so knew that EU funding for infrastructure was not reallly a benefit.

        • brnt 2 hours ago

            Austria is a net contributor to the EU, contributing 30% more than it receives (very roughly contributes 3 billion and receives 2).

    • fzeindl 3 hours ago
      It is mostly within budget, estimated in 2005 were 5.5 billion €, total cost as of today are 5.9 billion €, the difference being largely attributed to the pandemic and later addition of sections.
      • franciscop 3 hours ago
        Sure, I'm just pointing out that this article doesn't follow the HN Guidelines, so I was confused at not seeing any mention of the budget within the article:

        > "Please don't do things to make titles stand out, like using uppercase or exclamation points, or saying how great an article is. It's implicit in submitting something that you think it's important."

              I opened the article expecting to see news about the budget and how they stayed within it, since that SEEMS like the biggest surprising news in a project like this. How is that overly pedantic?

                I understand your expectation. That said, I think it's ok to add detail in commentary when the article doesn't mention it explicitly. So continuing to go upon the point that the article didn't mention the budget makes you seem as pedantic.

                There are non-English articles on the budget too.

            • fzeindl 2 hours ago
              In a world where large infrastructure projects regularly exceed their budget by 100-1000%, 7% is huge.

              It is important to show people that that is possible in government projects.

              If you find a more concise way of saying „with unusually small overrun of it‘s budget“ tell me.

              Also there were sections added after the initial estimate.

              • tomhow 1 hour ago
                Does the site mention the budget and completion time/cost at all? I can't find it from a quick browse/search of the site. It's taking editorializing to a whole new level to add details that are not in the linked article or site at all.

                The right thing to do in this case is find the best source for this information (about the budget, schedule and completion time/cost) and make that the URL of the submission. Please email us the best links you know of about this ([email protected]) and we'll consider updating the URL.

        That’s incredible! The project managers and contractors should collaborate on a book about how they did it. Heh staying on budget should be the norm and not the exception but irl a 20 year large infra project coming in that close is something to celebrate and learn from.

        To contrast, HS2 here in the UK has cost £40 billion (€45 billion) to date with a further £25 billion (€28 billion) allocated, for a largely superterranean route of 230km.

          As badly as HS2 has been run, apart from the tunnel length (where HS2 has not too much more than this project) these projects are night and day different. Not just that HS2 Phase 1a/1b is almost double the length and significantly higher design speed (360km/h vs 250km/h), but they are in a different league in terms of civil engineering from the info I can see - this seems to have less than 80 structures (overpasses, bridges, underpasses etc.) whereas HS2 has 175 bridges and 52 viaducts, and some of those are massive (including the longest railway viaduct in the UK).

            Doesn't tunnel beat any of those structures in terms of cost/complexity?

              Not necessarily because no one lives underground and there are probably no existing things like property, gas lines, electricity lines, sewers, pipelines, roads, etc to avoid or reroute. And very little in the way of habitat.

              The longest road tunnel in the world only cost about 100 million in the 90s for 25km so tunneling isn't always a gigantic Big Dig style clusterfuck.

              In terms of legal complexity, it's fantastically easier than picking your way across and near thousands of individual plots of very expensive land owned by people with solicitors salivating at the potential fees, expensive private infrastructure, nature reserves and so on.

                Big Dig style clusterfuck is because the simplicity and cheapness you're talking about only apply to tunnels through mountains, less so to those underwater and definitely not to tunnels under big cities i.e. land that people live on, which comes with all the complexity.

                • georgefrowny 2 hours ago
                  Yes, and the Austrian route is mostly in that category under the Koralpe Massif rather then the very politically awkward Home Counties (NIMBY Central, and very rich NIMBYs at that).

                  Hence why tunneling does not necessarily mean a stunningly expensive project. We just hear about the HS2s and Big Digs because they reverberate for decades with all the legal battles.

                The big dig is probably the last major success of American infrastructure. Referring to it as a clusterfuck is representative of why we'll never get another one.

                  IT is also correct - it costs way too much for what we got. It will be nice for future generations that don't have to pay for it, but it doesn't look like a good investment. Now if the costs were more reasonable it could be a great investment.
                  • MangoToupe 1 hour ago
                    I don't see how you're justifying this. Yes the costs overran, but the investment would have been worth it at 4x the end cost. It made boston one of the nicest cities in the country, even if it still sucks ass to drive in.

            HS2 also includes major stations - a 6 platform one almost entirely underground in west london, a multi-platform extension in central london, a new station in central birmingham, a new 4 platform outside of Birmingham

          Would be interesting to read how the Austrian project was contracted out? It seems in the UK the big construction companies have got very good in extracting a lot of money from customers, wonder if things were different in Austria with this project.
          • aa-jv 2 hours ago
            Austria tends to have pretty rigorous bean-counters overseeing budgets like this, especially when it comes to public-good services such as railway.

            It is one of the things that makes living here so .. infuriating at times .. but also .. rewarding.

            • zzbn00 1 hour ago
              Interesting. In UK, I think the big construction companies would hire these bean-counters then use them to out-manoeuvre the ones that are hired to replace them. Quickly nobody knows what a reasonable price is, and the govmnt has to go with choice of one out of two overpriced bids. (I have no direct experience, this is just what it looks like from an observers perspective)

        • monster_truck 3 hours ago
          7x longer for 11x the cost seems pretty good all things considered.

          Always thought it seemed like a waste to not also dig out a bunch of storage while we're down there. I'm sure there are good reasons we don't

          • oniony 3 hours ago
            It's not seven times longer. The Austrian line is 130km with 50km of tunnels.

                        Length  Tunnels  Bridges   Stations   Cost
                Koralm  130km   ~50km    100       12         €6b
                   HS2  230km   ~75km    100+      4          €74b+
            
            Obviously this does not give any indication of the complexity of each project. Tunnelling and building railway through a metropolis I would imagine is quite challenging.
            • monster_truck 33 minutes ago
              HS2 is five sets of twin bore tunnels, so there is more "tunnel per tunnel"
            • rsynnott 2 hours ago
              As far as I can see, the 6bn is _just_ for the big 30km tunnel? Presumably the rest of it cost more.
            • shevy-java 3 hours ago
              Still seems insanely more expensive in the UK. I understand they have a higher cost to carry because their project is indeed more complex, but that's like a almost 13x more expensive variant, while not even being two times the length.
            • orthoxerox 2 hours ago
              Sounds like you might want to build the whole HS2 underground to save money.

        Started in 1998, apparently without a budget, which came 7 years later, and was completed within…mostly…budget, but not really since it was 7% over budget.

        Which also begs the question; why is a railway project page on HN at all, regardless of anything else?

    > Crossing the Koralpe massif more quickly and with more comfort. That’s what the future of train travel from Graz to Klagenfurt looks like. With the Koralm Railway, you will arrive at your destination even quicker. The fastest connection will shrink from three hours to just 45 minutes.

    There aren't any big mountains between Graz and Klagenfurt. It's an hour on the Autobahn. That it took three hours by train... well, they just had shitty railroad? Best of luck, Southern neighbors!

    • syberspace 2 hours ago
      There is, the Koralpe massif. Previously to get to Klagenfurt from Graz you first had to go north through a somewhat tight valley for about 50km before the train would turn to the south-west towards Klagenfurt, again tough alpine valleys, and with a lot of stops inbetween. The new route goes south/south-west immediatley, is very straight compared to the old route, and has at most 3 stops.

      > they just had shitty railroad

      The terrain is just hard railroad had do huge detour on this section

      Look at map: https://mapy.com/en/turisticka?x=15.0703419&y=46.7076432&z=1...

      Passes in those mountains are only ~1200m above valley level (~1650 abs). Yeah, perfectly ok to run railroad there.

      Your autobahn climbs 600m on this section (to 1050m absolute) - it's way to high for railway to be effective.
