      Yeah, all the infrastructure is designed to withstand that. For example, all the tunnels have "muzzle brakes" like on artillery guns to dissipate the shock-wave from the trains exiting at 300 kph and above. Otherwise there's probably be detonations every time a train passes through.

      All the technology that has made France put on the podium of the advanced nations comes from the desire of De Gaulle and then the following presidents (and not only in 1981 but from the 1960s of the projects that were finalized in 1980/1981) to invest in rail transport (TGV), telecommunications (Minitel), energy (nuclear power plants), air transport (Concorde), the space programme (Ariane rocket) car transport (motorways) and finally the army (aircraft carriers, nuclear submarines, nuclear missiles, fighter jets...).

    Fun fact:
    They told the driver not to go over 575 km/h, due to danger of ripping off the catenary (power wires) due to standing waves, because there was danger of train being faster than wave inside the wire, made by pantograph. Wires were tensioned to 600km/h standing wave.

    The secret of this success is a perfect alliance between the rails and the train. The TGV tracks are built with absolutely drastic specifications, which allows for perfectly linear rails, without any disturbance, over a very long distance. This is why at more than 500 km/h, you do not feel any vibration or jolt when you are on the train. The train, for its part, has an electric propulsion system of unequalled power, allowing it to sustain this speed, and it also has a revolutionary suspension system allowing it to eliminate any jolt.
    In France, thanks to the TGV, you can travel from the centre of Paris to the centre of Bordeaux in 1 hour 55 minutes, whereas by plane, the time for boarding and disembarking, and the travel time between the city centre and the airports, it will take you 3 hours in total.
    And incidentally, electricity in France is nuclear or renewable, therefore zero carbon...
    The plane for domestic flights in France is totally out of fashion
    And you are right, the TGV record is 574 km/h but in commercial use, it runs at a speed of 320 km/h (200 mph). Records are there to allow an increase in the commercial speed, with a 100% guaranteed safety level. With each new record on a given section, the SNCF authorizes an increase in the commercial speed.
    There is also another consideration to have: it is the cost of electricity. If we drive beyond 400 km/h, the friction is such that we consume much more electricity proportionally. Commercially, it therefore becomes difficult to profit from driving at speeds exceeding 400 km/h, even if it is entirely possible.
    And about China, it's not comparable with the TGV, because it's a magnetic levitation train. The TGV is using classical rail system which is much less expensive and complex to set up

Les Shinkansen ont leurs propres rails qu'aucun autre train peut utiliser. Donc aujourd'hui les TGV sont toujours les trains les plus rapide du monde sur rails classiques, et c'est un énorme atout économique, car les TGV peuvent rouler sur les rails classiques, alors que les Shinkansen et encore plus les maglevs demandent des infrastructures bien plus couteuses et inutilisables par autres choses.

    As a railway enthusiast living in eastern France I can tell you ; for this record they “Tweaked” the line- with a higher frequency (31kV) higher over banking in the curves and a stronger tension in the overhead wires - and the Train - slightly bigger wheels for the “Motrices”… After the record run they had to “maintain” the line and opened it several weeks later…
    I remember the record being broadcasted live in the national news that day !
    Btw, the speed of 320km/h is enough and higher speeds demand an excess in energy consumption. For the European market it seems to be enough.

      Higher overbaniking? Are you sure about this one? Cause it would mean pretty important works on a line just for a speed record, to be then restored to normal high-speed banking in order to open the high-speed line for service...
      That's way too much hassle to change the rail geometry twice, so close to the opening date.
      Plus, there was regular testing for commercial services at the same time, and they would have to do it all over again if they had changed the geometry.
      Changing the voltage, frequency, intensity, and pulling tension of the catenary is just tweaking, it's quite easy. But changing the canting (over banking) is a whole different world, it's structural and requires a lot more precise and complicated works than catenary tweaks...
      Plus, I've never heard that the line was structurally modified for the speed record.

    It was shown on TV, and I remember they explained that everything was optimized to be as fast as possible, the catenary was stretched so that the train wouldn't catch up with the "waves" created by the pantograph which would essentially cut off the power supply, rails had been renovated on that stretch of track (or maybe it was the latest line to be built? Can't fully remember), and yeah, basically no one on board, and a way shorter train than what's in circulation.

    This train was a special test train for the record, although the two locomotives were from the main serial units, their wheels were modified and the central cal also had two powered bogeys to augment power to weight ratio, the catenary is usually about 25 kv but was raised to 31 kv to not burn the circuitry.
    That train set has 3 coaches, a usual TGV has eight, a double set has sixteen. On Atlantic line to Britanny, the sets have ten coaches and twenty as a double set, those can reach 500 m long in that configuration.
    The Eurostar had 21 coaches and the central car was an additionnal power car with some boost given to coach 1 and 21 to the two locomotives for extra power needed to start up the train from a standstill from the bottom part of the Channel tunnel, a security requirement.
    The normal speed on High Speed Lines in France is 300 kph, some go up to 320 (like the Eastern one which has the longest straight section of all HS lines in France. The latest lines could be theorotically by brung up to 350 kph if needed.
    As a matter of fact, the first high speed modern projects were drawn by an inventor, Jean Bertin, with a ROCKET hovertrain on a inversed T shaped concrete track. Of course, the TGV is a train that is compatible with existing infrastructure so it was less expansive to build than a complete new network of small units that wouldn't have given the necessary passenger capacity anyway... not to mention tha the oil crisis came at that very moment to make kerozene powered trains prohibitive...
    Note that, contrary to the usual way, the train runs on the right side. (however the HS lines could run a train on either side anyway, the signals are designed to allow this).
    Notice the electric bolts from the contact with the catenary. It's physical tension was increased to maximum for it to hold the shockwave of the pantograph running at such speeds. (it's usually already double the pysical tension of a normal catenary, here it's four times ! )
    In 1991, an Atlantic TGV set with similar modifications reached 515,3 Kph.
    The objective of that test was to go over 150 m/s, hence the train name V150. (150 meters being approx the length of the train set itself)
    The advantage of the train is that usually, you have stations in town instead of away from the town like an airport.
    When Japanese Shinkansen opened in the sixties, it was called "The Bullet Train" for a reason...
    China caught up a lot in the last few years. 30 years ago, it had among the worst trains of any big country in the world... China bought a lot of tech from Europe and Japan to mix the whole in their own fashion. Their HSTs are now a mix of German and Japanese trains, mostly.
    Running faster is possible, however, the faster you go, the more demanding the train is in maintenance and mostly in Electricity. It's bloody expansive. China can affort it to boast that they can run the fastest trains (and the distances in that country also kinda call for it), but how many COAL powerplants do they need to run those lines???
    No wonder they are going nuclear these last few years... The Three Gorges Dam can only do so much.

    The SNCF has a very union culture with long standing traditions. Well, one such traditions was that train drivers and engineers would invite their families aboard for test runs, specially the most prestigious ones. That was until the 2015 Eckwersheim derailment when it became immediately obvious why that was a terrible idea. 11 people died, luckily all the children onboard survived (yes, incredibly there were children, and that was quite normal until then). I think to this day those are the only fatalities in the history of the high speed network.

The V150 set consisted of two motor cars, with three double-decker passenger cars inserted between them. It had larger wheels and increased AC voltage from 25 kV to 31 kV. The engines powering the three bogies were rated at over 25,000 horsepower.

    This train was a heavily modified prototype, all the axles were motorized instead of the normally 4 extremity axles only, radius of the wheels was augmented, tension in the catenary was upped from 25 to 31 KV, only 1 pantograph, shorter composition, it was a one of a time trial. They got the record for the fastest railway stock on a closed to exercise railway.
    The record for a train in exercise configuration is held by the Italian ETR400 - Frecciarossa 1000, which in standard configuration reached on the Turin/Milan high speed rail the speed of 396,4 kph during the campaign to get omologation for a commercial speed of 360 kph, which was not reached by 3,6 kph ( omologated commercial speed is the maximum reached speed divided by 1,1). The train is the fastest omologated train in Europe with a max commercial speed of 350 kph, and as of today works in Italy, France and Spain with projects to expand in Belguim, Netherlands, Austria and Germany.

Doesn't take away from the fact that it's impressive AF. And living in France, the TGV is a ton of fun because I can do Lyon to Paris in about 2 hours; driving it's anywhere from 4 to 5 hours if there's no traffic.

    The reason TGV trains run so smooth is the flatness of the tracks - at upwards of 350km/h you really can't have any bumps or deviations - inertia of the (already quite high mass) train increases by the cube of velocity, so it would be putting enormous forces on the tracks and suspension of the train at high speed, and passengers could get jolted. This test used just a few cars to reduce mass and air resistance; TGV trains has two powered motor cars; one at the front and one at the back. Any additional passenger cars would just increase weight and air resistance of the train, thus lowering the max attainable top speed and stressing the tracks more.
    TGV also features the boogies between each car, rather than under the cars. This helps to increase comfort, as well as reducing weight and rolling resistance (one less boogie needed for the full train).
    Fun fact: they mention the motor cars pulling 800 amps off the grid, at 31 kilovolt. That's nearly 25 megawatts of power! So a small city's worth of electricity just to power one single, short train at high speed. :D That's mainly because of air resistance, which also increases exponentially with velocity.

According to the technical specifications for the interoperability of the high-speed rail system, high-speed trains should be able to reach “around” 200 km/h on upgraded lines, at least 250 km/h on new high-speed lines and “in appropriate cases” a speed of over 300 km/h (190 mph). For high-speed rail vehicles, all components of the railroad system must be adapted to the higher requirements. In addition to the high-speed train, a special high-speed line and a correspondingly efficient train control and safety system are required.
    Vehicles for high-speed transportation are predominantly electrically powered. Diesel or gas turbine traction units have been tested on several occasions, but are the great exception.
    In rail transport, a high-speed line is a railroad line on which speeds of at least 200 km/h are possible. Some international definitions provide for higher speeds. In addition to an appropriate alignment, which must be able to withstand the high loads, high-speed lines must not contain level crossings, and passenger safety systems must be provided if trains pass the platform at speeds above 200 km/h. The overhead line must also meet special requirements. Special demands are also placed on the overhead line: Contact wires made of a special alloy are used to improve electrical contact and prevent flying sparks.
    With the long acceleration (around 7 km) and rapid braking distances (over 3 km) involved in high-speed traffic, the traditional signaling system with track blocks is no longer suitable for covering trains, as the block spacing and slippage paths would have to be immensely long. This also conflicts with the short train sequence required by the timetable. High-speed trains are therefore no longer controlled at specific points along the route by fixed railroad signals with requests to stop or slow down, but by constant radio contact.
    Essentially, the following factors limit the increase in maximum speed:
    - Smooth running
    - Wheel/rail adhesion
    - Air resistance
    - Power transmission
    - Noise development
    - Economic efficiency
    - Operational coordination

    It must be taken into account that this is not a normal train, it was extremely and specifically modified to beat the speed record, that includes the Track and Overhead line itselves, it's the fastest train on rails but not the fastest one built in series. That said, it was amazing to see that on TV.

    This TGV (fast-going-train or Train à Grande Vitesse) is only met for records and tests. The true train is two locomotives and up to 8 cars. The record, still french TGV, is 357 miles per hour. Normally, on a TGV, you travel around 200 miles per hour daily.

    In Indonesia, our Bullet Train goes at a speed of 600 km/h or 372 mph, but is pulled by 3 units of F-35 Lightning 2 haha.. Just joking. Actually our bullet train called WHOOSH only 350 km/h or 218 mph at regulated of operating speed, max speed testing record at 260 mph. In fact, the run is smooth and not shaky at all but we felt a little bit dizzy at speeds above 300 km/h. But I think, even a bullet train is more safer of transportation than an airplane. Please uncle, check out or react to the video of many foreign travelers who have used it like Wasseem Way, Alexander White or others.

    You have Acela Express on the NE corridor which hits 150mph with the new generation of trains set to go even faster. Unfortunately it can only do those speeds for pretty short sections of the entire line. California is currently building a high speed line that will reach European speeds and a line is planned from California to Las Vegas that will be similar. Apparently Texas is in the very early stages of planning a high speed line too, so maybe in years to come the US will have a few genuine high speed trains of your own.

    Meanwhile the Amtrak express is still waiting on a sidetrack due to a slow-moving freight train with a faulty bogey...

    This is a world record of a conventional train going on conventional tracks.
    The trains going faster in China and Japan aren't conventional, they have magnetic tracks and of course they go faster both during tests and with passengers.

    Mach 0.45.
    Sadly I don't think we'll see supersonic trains in our lifetimes.
    _Maybe_ transonic
