The Problem With Fast Trains: What Happened to Hovertrains?

49876 ratings | 4268606 views
In 1974, a French train sets a speed record, exceeding 250 miles per hour. But this train is unlike any other before it. Instead of rolling on train wheels, it hovers on a cushion of air. In the 1970’s hovertrains were seriously being considered the solution to slow, antiquated railways, which increasingly had to compete with new superhighways and even intercity air travel. Without the rolling resistance of train wheels, hovertrains promised greater efficiency and much higher speeds. By feeding high pressure air through lifting pads, hovertrains float on a cushion of air much like a hovercraft. One of the most widely known hovertrain prototypes was called the Aerotrain. Lead engineer Jean Bertin and his team in France, designed several versions, including one that could carry 80 passengers. The i80HV was powered by a turbofan sourced from an airliner, producing over twelve thousand pounds of thrust. At the front, a 400 horse power gas-turbine supplied high-pressure air to hover the twenty loaded train a quarter of an inch off its guideway. The British and Americans also experimented with hovertrain technology, incorporating the linear induction motor for improved efficiency. British research led to the development of the RTV-31 Tracked Hovercraft, and the American’s developed several prototypes, culminating in the development of the Urban Tracked Air Cushion Vehicle (UTACV). But like their counterpart the Maglev, Hovertrains failed to revolutionize rail. Hovertrains, Maglevs, or any other innovative alternative to rail has to compete with nearly a million miles of rail line already in existence. With stations and infrastructure built-out in nearly every city in the world. The limitations of conventional railways were overcome not a single innovative leap forward, but by incremental improvements. Existing rail networks were modernized with sections of track that could handle higher speeds. New signaling technologies were developed along with more advanced wheelsets. #Hovertrain #Aerotrain #TrackedHovercraft #YesterdaysFuture The first 200 viewers to sign up at https://brilliant.org/mustard will get 20% off their annual premium subscription Want to help Mustard grow?

It is a shame you failed to mention Spain, which through RENFE and it's AVE program (Alta Velocidad España, also the Spanish word used to refer to big bird species) operates de LARGEST High Speed Railway network in the whole of Europe. AVE trains have a cruising speed of 310km/h around the aproximately 5000km of railways built throughout Spain.

In a word: oil. As long as oil companies keep making trillions of dollars every year we will NEVER see high speed mass transit like this in the US. Big oil wants us enslaved to them. Its only a matter of time before they destroy Tesla - the oil companies fear any technology that replaces fossil fuel, and they will KILL anyone who gets in their way. Research the man who created a hyper efficient carb and combustion chamber for autos. He mysteriously died, and his research materials and prototypes vanished.

Rothschild , Rockkfellers etc.... make too much money out of oil and cars to let this go down for trains . In the 60 's , GM and other car companies bought inter city bus lines . At first , they gve the same service as old owners . Then , they start reducing hours , number and other facilitating ideas so that peoples said to themselves : I'm better off with a car after all. And that what has happened . Do you realy think that crooked more than hell LBJ , who became billionnaire a few months after becoming US president , who was deeply involved in Texan oil , JFK assassination and Viet Nam false flag war triggers was realy working for train solutions?????? Hell will never be enough warm for peoples like LBJ, such a crooked man , even HRC is not up too.

SO you talk shit about the USA when WE invented Maglev tech in 1910... AMERICAN CITIZEN Emile Bachelet invented it. French born but American due to that little thing called freedom and the fact that we were far ahead of any other nation. In fact, the USA is responsible for just about every technological advancement in the 19th century and the 20th century into this 21st century. You know, the industrial revolution that started after the USA invented petrol fuels... yeah that was us as well. So, France tried and failed as usual while we, the USA perfected Magnetic levitation that WE invented in 1910.. yeah not impressive France. Oh and that jet board they "invented" is from the USA as well because we also invented Jet engines as well as the fuel to power them. Not to mention the drone technology that is used widely and the computer you typing on. Seriously, show some respect. France would be speaking German right now if not for us, the grand ol USA!!! I have been to France and they can have it. Dirty as can be with water running down the streets to rinse feces down into the city drains.. IT IS SO DISGUSTING! WE have a homeless problem in some cities but there is a huge difference between homeless folks and a national acceptance of shit rolling down the street in EVERY CITY. What you fail to realize is that WE are a nation of every people around the world, they came here in search of freedom and found it. In other words, we are all of you, just the best of you together in one place. Your welcome.

Interesting video, thanks! I rode on a Japanese demo maglev train at Expo '86 in Vancouver. Smooth! Now I'm working on high speed transport over water. My evolving Ground Effect Craft design with its latest improvements should be far more seaworthy than previous ground effect craft, flying just over the waves at small aircraft speeds with very low fuel/energy usage.

Compared to a high speed train it has a lot of disadvantages. The capacity of those units is pathetic compared to a TGV, since the oil crisis operating costs would be increased and not to mention the noise and polution it would take in the city centers. Maglev is a better alternative but only for long distance lines

aftonline (1 month ago)
The problem with high speed trains is not the trains themselves but the infrastructure needed to support them. In theory, vactrains could travel faster than the Concorde over long distances, but nobody can afford to build the vacuum tunnels, particularly across oceans or across mountainous regions. Even maglev lines, which have already been built across short distances such as the Shanghai airport train, would be prohibitively expensive to build over the thousand-mile plus distances where they would really shine. The bottom line is always the bottom line.

The number one problem? My guess is terrorists! They could easily cause a catastrophe, with a derailment or a blown bridge. My 2nd guess may be money.

A lot of facts and a few fallacies. Adoption was not stunted due to recessions. It was stunted due to lobbying. Airlines don't want more efficient ground travel cutting into their profit margins. That's why in the US, Amtrak is still a government funded service - were it to go fully private, you'd see private investments in that infrastructure. Hyperloop may or may not turn into a thing, but it being private means there is at least a chance of something coming of it. The real concern is whether or not there can be a complete end-to-end solution. A person has to be able to get on whatever and go wherever. That's hard without infrastructure, which costs a lot of money to create. Improving the current rail system is fine and likely way cheaper, but does it make sense for the long term? In a perfect world, we would have capital-to-capital trains with no other stops at highest speeds possible; dirigibles for in-state city-to-city travel (think Sac to Los Angeles, as an example); planes for more expensive (because it's faster) travel to states or international. No city or state capital should be able to refuse to implement any of those three. Just adding back dirigibles alone would likely cut the majority of traffic for commutes.
