High-Speed Transportation of the Future: Is 760mph Possible? | FD Engineering

Virgin Hyperloop out of business 8 months ago.

[@toraxmalu]

not only that - Musks Hyperloop aswell and all the other attempts of this "technology". It was a still birth from beginning. That starts with keeping the evacuated and emptied tube sealed and void of air, goes on with "how to prevent a disaster in case of a collapsing section" and ends with "how to bring out the air in a short enough time"… with the bullet trains we've already the technology and it is compatible with the existing track-system - you need "only" upgrading the existing tracks and adding new straighten sections to reach really high speed. and 300 km/h (180 mph) should be enough to cover long distances…

[@Bob-Jenkins]

​@@toraxmaluElron's Hype rust bucket line has been completely dismantled now. First they removed part of it for a train track, (irony much) now it's all gone and replaced by car parks. I mean the jokes practically write themselves, actually the whole thing is a joke in and of itself. They should be figuring out how to get passengers in and out of the "vacuum"…maybe they'll have oxygen bottles available in the gift shop. Expansion joints for a track 100's of km long, the top and bottom of a metal tube will expand at different rates, so it's not just about length but also having it turn into a roller coaster of doom. It just seems like an illogical project, and I'm not the one in the family with PhD's, so I could be way out of line with my concerns. As long as the "white paper" is as well thought out as the Cyberchuck, what could go wrong.

[@kibashisiyoto6771]

I don't know why anybody thought it would be cheaper than high speed rail. Musk originally claimed it would be 1/10th the cost, even though it requires roughly the same amount of steel and concrete, but laid and maintained to much tighter linear tolerances. And then it's still a low capacity system if you use any reasonable safety factors for braking distances, etc. Also, I'd like to see somebody solve the problem of dynamic amplification. This is what sets up vibrations within the tube structure. Hyper loop would be traveling at such speeds that the dynamic amplification factors would be much higher than has been engineered for before.

[@celebrityrog]

Hyperloop and contrained vacuum tube transport is simply science fiction. Point blank, nothing about the hyperloop is innovative and speeds achieved in the tube can be achieved outside the tube. If you're trying to kill off friction, design the train to be more aerodynamic, like the ones in Japan. But as far as I can tell, pneumatic tube travel ended back when Subways became a thing.

What could possibly go wrong traveling inside a vacuum tube expanding and contracting over huge distances at high speed? 1. The tube would buckle down under atmospheric pressure. 2. Any loss of capsule pressure would doom the passengers, caught in a speeding tube without emergency exits.. 3. Any mechanical failure would trap the passengers inside a vacuum tube without emergency exits. … Death trap

[@Hans-gb4mv]

1) we know how to build tubes that can withstand the pressure. Hell, look at an aircraft, how thin its skin is and the pressure diff between the inside and outside. 2) emergency oxygen can be carried on board of the capsule, just like in an aircraft 3) in case all traffic is stopped, the tube can be pressurized and you could still include emergency exits.

[@douglasengle2704]

China's CF600 maglev EMS prototype train testing at over 600 kph with goals of 800 kph is very likely the first practical high speed maglev. It levitates at at standstill and requires no landing gear. A new maglev train standard in full scale implementation should start a new much wider loading gauge of about 8 meters wide or more. A double width loading gauge has been envisioned and was provided for at the beginning of the railroad age on 1840s UK dual track railways that were designed to occasionally have double width carriages using the inner rails of the dual tracks. Maglev trains don't have the load limits of the rail wheel interface and are able to support loads distributed across the track bed. An 8 meter wide loading gauge would allow the easy transport of large assemblies overland greatly changing the world. Three TEU shipping containers should be able to fit across a cargo car's width. An 8 meter wide loading gauge would allow stability for three passenger levels. The first level might best be used for cargo with perpendicular side simultaneous drive-on drive-off of automobiles and cargo containers that could take place in a one minute stop. High speed cargo might make profit. Passenger trains tend to not make profit. The second and third levels could be luxury continues passenger space with vista dome roofs for passengers to see forward watching the scenery. This configuration would allow more comfort for the same number of passengers in 1/4 the length of today's popular single level trains that stretch out several city blocks. The train can depart as soon as the automobiles are loaded with enough space around the parked cars for passengers to take their time collecting themselves to exit their cars and go upstairs to the passenger areas. Loading and unloading needs to be staged and simultaneous to allow 1 minute stops. The unloading and loading of roll on cargo and automobiles should be able to work much like a traffic light stop and go. High transfer passenger stations could have exit and entry between the staton at all levels of the train to speed loading. Rural stations with small numbers of people would have loading at level 1 cargo level with passengers having to go up internal stairs to the passenger levels. Having train speeds much above 1,000 kph (621 mph) which can start causing sonic booms has little time saving advantage when stopping every 160 km or 100 miles because of time spent changing speed and stopping for a one minute stop. With changing speed these stops would only be a bit over 10 minutes a part. This would mean if intending to have regular stops within reasonable driving times to train stations it would be better to allow sightseeing from a passenger train staying below the speed of sound than to put into a vacuum tunnel to enable super sonic travel where there is little to see. Using 2/3 of the running speed of 621 mph to give a rough average speed of 400 mph wound mean such a train could cross the width of the USA of about 3200 miles in 8 hours. All very high speed trains need incrementally cheap to free electricity for their huge electrical demands such as their own hydropower generators with unlimited water. New technology nuclear power is likely the next closest option. The Japanese SC maglev has a loading gauge width that is similar to cape gauge railways of 3'6" gauge common throughout Japan that is significantly less wide than the current standard gauge Shinkansen bullet train. The SC maglev uses a non static levitational system dependent on the train reaching about 140 kph before it starts to levitate. Below that speed the train has to use retractable landing gear. These aspects make the Japanese SC maglev not desirable for a new train age where much wider loading gauge and no landing gear are desirable.

[@mls515]

I've been on the Chinese high speed trains. Very impressive, over 300 km/hr. I bet they just took the land they needed to build the lines. And I bet they had no lengthy environmental reviews, no legal challenges, no hold-ups over half-extinct crickets or any other nonsense that slows these projects to a ridiculous pace in the west.

[@madsam0320]

Using high speed trains to ferry cars long distance is a brilliant idea. The average use of a car is commuting and shopping trips with occasional long distance trips per year. There is no need for lugging a heavy battery for EVs, bad for the environment and limited resources. A small car is comfortable enough for short distance, for long distance, even the most luxurious car is quite a tiring experience. On a train, there’s no need to drive, and we can relax with dining and washroom facilities.

[@raghunathkrishnan5124]

The problem with any maglev system is the cost per mile. Germany pioneered it the 1980s with TransRapid but they could prove running only one commercial one in Shanghai so far. Japan's L0 maglev is still a test track. They promised 2034 for passenger traffic. China is starting up.

Even IF they solve all technical obstacles there will never be financial and/or political unity to make them real. At best a limited US and EU domestic system could be built again IF cost gets low enough and political unity winns the long run. It is a interesting idea but not a realistic one. To make a workable system you would need a air filled tube with fans pulling air into ducts in the pod exhausting it below and behind, like a hovercraft having skirts to guide the airflow. you then have magnetic guide tracks on the sides and below and a wireless induction charger at the top to continually recharge/power the pod. That powered by solar panels covering the top 1/3 of the tube and with batteries along the track to provide backup power or even night travel. I do not know if you get a sonic boom if you suck away the air in front of the pod but I would think it unlikely as the pressure never builds on the leading surface. This should allow supersonic travel at a fraction of the cost compared to flying.
