TGV Unveils High-Speed Trains of the Future (cnn.com) 98

An anonymous reader quotes a report from CNN: French railway company SNCF and train manufacturer Alstom have unveiled the first completed TGV M, a next-generation high-speed double-decker train that features a longer, more aerodynamic nose -- perfect for hurtling across the French countryside. Alstom dubbed the new train "the TGV of the future." TGV stands for Train a Grand Vitesse, meaning high-speed train. This swanky new design will premiere on the Paris rail network in 2024 and across the country over the following 10 years.

TGV is one of the world's most famous high-speed train brands and has been a staple of European rail travel since the early 1980s. Back in 2018, SNCF, the state-owned French railway company which controls TGV, ordered 100 TGV M trains (also known as Avelia Horizon trains) at a cost of 2.7 billion euros (around $2.7 billion). An additional 15 trains were ordered in August 2022. The majority of the trains will operate within France, but Alstom has said 15 will ride the rails internationally. TGV M will operate at the same maximum speed as the previous generation of TGV trains -- 350 kilometers per hour (nearly 220 mph). "In 2022, we don't want to go faster," said Alstom spokesperson Philippe Molitor told CNN Travel, explaining that the goal instead is high speed trains that accommodate more people while consuming less energy.

TGV M trains don't just have 40.5-centimeter (15.9-inch) longer noses than their predecessors, they're bigger all round. Roomier carriage interiors can accommodate up to 740 seats, compared to the current maximum of 634. TGV Ms also got what manufacturer Alstom calls "unprecedented modularity," meaning the train's interior configuration can be easily adjusted. A carriage can be converted from second class to first class and back again, or adapted to allow space for oversized luggage or bikes. There will also be dedicated on-board passenger social areas to offer variation and flexibility on longer journeys. According to Alstom, the design improves TGV's current energy efficiency and carbon footprint, with 97% of the train's components now recyclable. It also boasts better accessibility -- there will be a lifting platform to allow wheelchair users to independently board the train, and an on-board sound system to aid visually impaired travelers. Larger windows will make the most of views while the TGV's lighting will adapt depending on natural light outside.

  • In North America, you've got vast distances and, over much of the continent, cold temperatures that make high speed rail an engineering challenge. On the other hand, you can provide downtown to downtown service, which saves a lot of time when you compare it to landing miles out of town, then taking some kind of shuttle over gridlocked roads to get to the same place.

Maybe some of those distances are a bit short, but the traffic on the QEW, 401 and 400 demonstrates how roads donâ(TM)t scale. There might even be sufficient demand for Toronto-NYC and Toronto-Chicago, with a similar model to how Eurostar has taken customers from airlines on the London-Paris and London-Brussels routes, but

      You think it doesn't get cold in Europe?

        This isnâ(TM)t high speed rail! The tolerances are much lower. Siberia would be one of the more challenging places with regular temperature ranges from sub -40 to over +35 Celsius, which I suppose would cause quite a lot of rail expansion and contraction. That said, Russia does have some ~250kph lines on the European side, and plans for a 400 kph line between Moscow and St Petersburg - if they can do it here, the environ

        While this is true, the temperatures are still quite different (not to mention snow volumes!). Having lived in Wisconsin, Switzerland and currently Denmark (amongst other places), I can tell you that southern Wisconsin is far colder in the winter than anywhere else I’ve lived.

          I, for one, am looking forward to trying out these new high-speed double decker trains. Travelling by train in Europe, city centre to city centre, with free WiFi & seats that face each other with tables in between & plenty of room for luggage, is so much more civilis

      In North America, you've got vast distances and, over much of the continent, cold temperatures that make high speed rail an engineering challenge.

      This is true of N America as a whole, but there are plenty of regions that have population densities similar to Europe that could be well served by high speed rail. The City Nerd Youtube channel did an episode a while back highlighting pairs of cities 400mi apart that had at least 10 local flights/day between them. These could all be candidates for rail links. And once you had enough city pairs linked, it starts making sense to link up regional hub cities with longer range rail.

      Well, I don't think anyone is thinking about building HSR links to Omaha.

      Shinkansen shows that a large HSR network can be operated profitably. And if you're thinking, "Well, Japan is a small country," I suggest you consult a globe. If you were to drive the entire length of the Shinkansen network from its southernmost to northernmost station, the drive would be over 2000 km and take 20 hours -- roughly comparable to driving from New York City to Miami. There are transportation corridors *within* North A

      • TGV is kind of in between; it can cover its operating costs but paying back the capital investment out of operating revenues is never going to happen.

        I wonder what the calculation would be for our federal interstate freeway system.

      • Sigh, Japan is a whole 377,973.89 km2 compared to the USA hitting in at 9,833,520 km2. Your 2000km train ride is closer to what it would take to get from San Diego to Seattle, one way.

        Then we take account that most of USA was built up with the car as the main mode of getting around. Japan on the otherhand has been around for many centuries and would likely be all around harder to get around with a car. The train probably stops at every little village's center and they are very likely walkable or at the very

          HSR only competes with airlines up to about 500 miles. San Diego to Denver is about 1,000 miles.

          But San Diego to Los Angeles, Phoenix, Las Vegas, and San Francisco/Sacramento are all feasible by HSR. Also possibly El Paso and Albuquerque, but Reno, SLC and Denver have some tricky topography to build through, and that drives up the cost of construction exponentially.

          • by hey! ( 33014 )

            I think that depends. Beijing to Shanghai is China's most successful line; the train trip takes 4 hours 18 minutes and covers roughly 1200 km. A direct flight takes 2 h 20 m -- significantly shorter, however you then have to factor in security and getting from the airport downtown if that's your destination. So flying is at best marginally faster, and the train is competitive even though the route is 50% longer than you stay is the maximum viable HSR route.

            But we do have to be careful about drawing anal

          • Okay, I live in San Diego (obviously) but more specifically Lakeside, about 25 minutes from both the airport and the train depot that would go to LA. If I were to use only public transportation, I would first have to travel 7 miles to the nearest trolley stop. To get to the coaster is anywhere from 1 to 2.5 hours, depending on the time of day.

            It's a doable bicycle ride to the trolley, although not very safe given our public surface road traffic, but then WTF do you do with your bike? No where to safely put

        • by hey! ( 33014 )

          I'm not sure what you're sighing about; I was saying that linking all of the USA by HSR doesn't make sense, particularly because it is extensive in two dimensions like China. However the East and West Coasts could each be served by a network that might look similar in geometry and extent to Japan's. The Midwest is a possible candidate for a more 2D network if you will, linking cities like Minneapolis and Chicago, or Saint Louis to Cleveland.

          • I must of took your comment a bit wrong at the time I read it.

            Don't get me wrong, I would love it if we would invest into a really useful public transportation system, but even in Democrat strongholds, we still don't have the political will to pull it off. It's very frustrating.

        • Then we take account that most of USA was built up with the car as the main mode of getting around
          Actually it was not. For long time it had excellent long distance and local train systems. Those got intentionally bankrupted - I think the oil industry was behind it. The people involved alll got convicted, I think you can goole that up.

          The train probably stops at every little village's center
          No they don't. We are talking about high speed trains, not local trains.

      • The original HSL between Paris and Lyon paid itself in about 10 years. It has since then paid itself nearly twice over.

        Profits are down from what they used to be due to lowcost airlines (which are **heavily** subsidized). The whole TGV network (running the trains) is a for-profit operation, it is not subsidized. It pays for track access charges that cover infrastructure costs. Same thing for Eurostar and Thalys.

        High speed rail is almost always a profitable business.

    • Parts of Japan and China have similarly cold winter temperatures and high-speed rail works reasonably well there.
      • To add to your point, China is also a similar size to the US, and has long distances to connect, but yet have successfully built a HSR network. Whats crazy is that they've done it all in the last ~15 years. They had almost no HSR in 2007, and now they have the worlds longest HSR network with something like 25,000 miles of track.

    ... are their larger wheels. Two carriages share a bogie with 4 wheels between them, so the wheels have more space and can be larger than in conventional carriages where the wheels must be crammed below the passenger deck. With their double-decker layout the TGVs only allow a connection between carriages on the upper deck and the lower deck sits between the bogies.

    The higher ride comfort made possible by larger wheels is very noticeable.

    • by hackertourist ( 2202674 ) on Saturday September 17, 2022 @02:58AM (#62889015)

      There are a bunch of factors that contribute to the TGV's ride comfort.
      1. Long sections of rail are welded together so you don't get rail gaps every 30 meters.
      2. Track is laid to tighter tolerances.
      3. TGVs have excellent suspension.
      4. The shared bogie design means the coupling between cars has no slack, so you don't get jerk as the train begins to accelerate or decelerate and that slack is taken up.

      • Who modded this as insightful?

        I don't think the poster has been on a train since 1950. All those features (except the shared bogie) are standard on modern railways, and modern couplings don't have slack anyway. But perhaps he has American railways in mind, they are about 70 years out-of-date.
        • by hackertourist ( 2202674 ) on Saturday September 17, 2022 @05:21AM (#62889121)

          I've been on TGVs, and on regular trains in the Netherlands and the UK. 2 weeks ago, I had several train journeys in the UK on old-style segmented rails. It's also easily noticeable that the lateral acceleration on regular trains is far greater than on any TGV high-speed section. Welded rail and shared bogies are becoming more common, but are not universal yet.

          • There is plenty of jointed track in the UK on secondary and branch lines, and there are lines where the standards of maintenance and alignment are not up to fast (conventionally fast) main line standards. The point I am making is that continuously welded rail, good alignment, and good suspension are not the sole prerogative of the TGVs. Also, I'd like to know on what trains in the UK you found coupling slack - unless it was a heritage line.
        • Jakobs bogies are actually quite common, especially on trams.

  • by johnw ( 3725 ) on Saturday September 17, 2022 @02:17AM (#62888979)

    I doubt it will "premiere on the Paris rail network". There would be no point in a TGV if it just ran around Paris. Their whole purpose is to cross France in as short a time as possible and the French government aims to eliminate short-haul flying in France.

    It might premiere on routes to and from Paris, but then most TGVs are on those routes anyway.

    • They aren't talking about Paris the inner city. They are talking about frequent trains from Paris to neighbouring cities. Many TGVs do not cut across the entire country.

    • the French government aims to eliminate short-haul flying in France.

      Such a goal seems obvious to everyone, except to the french government, unfortunately. If this is one of their goals, they hide it very well.

    • by Badoit ( 2618265 )
      SNCF use separate power cars at the ends of double-deck ('Duplex') TGVs, because the passenger cars have, necessarily, lower floors than single-deck ones, and that means there's no room for the traction equipment (transformers, inverters, etc) to be placed under the floor, as is now common in single-deck designs.
      • by spth ( 5126797 )

        The Japanse E1 and E4 series are double-deck high-speed (240 km/h) trains with distributed traction.

        AFAIK the Stadler KISS for Caltrain (to enter service in 2024) will run at 201 km/h, and thus will be a high-speed (AFAIK the usually used definition requires speed above 200 km/h) double-deck train.

        • by Badoit ( 2618265 )
          The KISS platform looks to European/British eyes like a commuter or regional multiple-unit, and, according to Railway Age, and others, the Caltrain ones have a maximum speed of 110 miles per hour (177 kilometers per hour). Still, nice trains.
    • Please check facts before you post.

      Alshom are a major train building company who will make whatever the customer orders. They make inter-city trains, metro trains, trams (streetcars), monorails and freight locos. They build trains for the London Underground for example. In the case of TGVs, they are multiple units (ie have several power cars), as are practically all modern passenger trains.

      While the Japanse South Manchurian Railway used a locomotive for its 134 km/h service (the fastest in Asia at the time) in the 1930s, Japan has been using distributed traction since they introduced high-speed trains (to the world) in the early 1960s: https://en.wikipedia.org/wiki/...

    ...our trains get worse. 1. Smelly dirty toilets, if the train has one. 2. Disinterested grumpy staff, I have plenty of video to prove this. 3. Ticket prices triple mainland Europe. 4. Unreliable arrival times. 5. Trains the same boring boxy clunky shape as the 70s/80s, with cram em in plastic seats. 6. With the exception of Liverpool Street, each station is still based on visionless dull 30s architecture. Compare Paddington to New York's Grand Central. Enough said. I went to Paris in 1989 and even then, the Metro and trains were more modern/futuristic and efficient than the best British train today, inc the Intercity 125. This is what happens when your country is run by the oil companies who would prefer we and trucks burn through petrol stuck in traffic. (I have an EV, so don't do the pollution think locally anyway.) Emigrating soon, back to US, although France tempts, where vision and imagination lead the way.
