I was curious about the rationale behind the relatively small size (or more importantly length if the vacuum tube is to be kept small) of the pod in combination with its roomy luxurious interior further limiting passenger capacity per Pod. Doing some napkin calculations for a hypothetical one way Munich to Berlin route for example shows: Currently serviced directly by ~ 20 ICEs per day at roughly 450 passenger capacity per train, making for a capacity of about 375 passengers per hour. Assuming then that the pod based on what was shown comfortably seats 5 people plus luggage and items such as bicycles, we get to a minimum pod number of 75 Pods leaving Munich Station toward Berlin per hour to achieve the same capacity as existing high speed rail. The plans on the website show arrival and departure areas on either side of the pods so I'll assume they service two way routes. So for each multiple of 48 Seconds of time that passes between: entering the boarding slot shown on the render of the hyperloop hub, opening the doors for passengers inside to leave, Passengers clearing the pod for the next passengers to board, the next passengers boarding, doors resealing, and beginning to move out of the slot An additional Slot has to be reserved for full time use for the route Munich - Berlin If I then assume (largely guesstimating times here so result may deviate from reality) about 5 minutes for the full cycle between arrival and leaving the station again, which I would consider a good time if elderly passengers etc are supposed to be able to comfortably follow the schedule, then two zones of 3 pods each would be entirely dedicated to a Munich Berlin route. That means 10% of a main hubs capacity is used for servicing a single major route, limiting the number of major cities that can be connected realistically to around 10. I feel like that is not a bad number to start with, its still 10 major cities successfully connected after all, but with the relatively higher speed Hyperloop offers also comes extra induced demand, if its no longer a big undertaking to travel far, more people will, intensifying the capacity issue. If instead a pod was given a more efficient layout, akin to a planes passenger cabin, you could comfortably fit 10 or more people, relatively more per volume if pods are made longer as the ratio of useable volume to the total volume of the pod gets better the larger the pod is (simplified but should hold true for the dimensions being considered) Taking into account that trips are very short the needed travel comfort for it to stay an attractive mode of transport is much lower than what is being planned, time of travel wise youre essentially competing with your every day bus, not a luxurious private yet flying trans-atlantic like the current pod design would suggest.
You have no clue what you're talking about. In highly populated areas the costs nowadays to build a high speed railroad are immense, plus you have to deal with tons of laws and rules that really slow down these projects. They also need to buy out a lot of landowners to build that railroad. With high speed rail roads you have to deal with rivers, mountains, roads, highways, etc, but you're also dealing with weather, vandalism, and all kind of other issues. You won't have a lot of these issues if you go underground. Even 80% of the 286 km famous Japanese Maglev train route is underground. You clearly have no clue what you're talking about...

Hyperloop concept makes no sense. It's neither cost efficient nor easy to deploy solution. It'll be much safer to build magnetic trains track than to build sealed tubes with vacuum inside and either conventional or magnetic rails to allow cars to move somehow. Even if anyone builds hyperloop line in Europe... how this could work. Imagine 500km line without ANY STOPS to take an advantage on Hyperloop speed. Point to point - how many passenger can it take within one ride. One car? Or 20 cars? Can it pick up 300-400 passengers at least? What in case of any medical or technical emergency. What if this train stop in the middle of the tube. How fire or emergency department will access it? It can't. What if tube deforms due to the pressure differences? If it bends to the inside - train can hit it and crash. Really easy target for any terrorists as they'd only have to break the tube to cause an accident. You'd need to wire everything and measure tube deformations 24/7. That'd be insanely expensive. What if train depressurizes - there will be a huge difference in pressure. If there is a pressure leak in the train - everyone dies. Hyperloop is supposed to achieve speed of 1200km/h. To benefit from that you need a distance of at least 1000~km due to the acceleration and deceleration issues. Europe doesn't have countries as large as China. This speed is useless here unless you travel abroad from let it be - Germany to Portugal.
I do not think you have done a complete analysis. A Hyper loop is not super sonic, nominal speed is 1080 km per hour (kph) is 18 km per minute or 300 m per second at 5 m per second per second ( about 1/2 g) acceleration it takes 60 seconds to reach 1080 kph, and requires about 9 km (300 * 60 * 1/2 ). In a 700 km route with 14 off ramp linked stations (1 every 50 km) the off ramps will add an extra (9*14) = 126 km (22%) extra tunnel length. I do believe there are many inter city routes in Europe of at least 50 km, a trip that will take less than ( 60+60 + (32*5=160) ) = 280 seconds just under 5 minutes. A pod set every 4 km is more than 12 pods arriving every 5 minutes or 144 pod sets per hour, 1440 to 7,200 people and that only requires 24 pod sets of 1 to 5, 10 seat pods. Isolation hatch every km means that emergency services will reach the site of a crash from a close city within 5 minutes, also means that isolating a section will allow emergency services reach and return from an exit hatch next to a isolation hatch to reach traffic pile ups and other disasters within minutes.

Q - given this thing is in a "vacuum", the pod is going to have to carry sufficient air for the passengers and scrubbers to remove the carbon dioxide. Where are they?
I'd like to know how long it took to pull a 10millbar vacuum, no way it was as fast as shown in the video unless that was 10millbar under atmospheric. I mean seeing as you would at minimum have to pump that volume down to go into a tube that is already under vacuum. My guess is that it took the better part of the day to do that.
10 millibar is 1 % of atmospheric pressure. Not a very hard vacuum. 1 Cubic meter (m^3) weighs 1.3 Kg, lets assume the tunnel has a cross-section area of 10 m^2 (meters squared) and a length of 100 m. The mass of air to pump out is (10*100*1.3) = 1.3 Tonnes, a single 777 engine pulls over 75 tonnes per minute, so less than a second.or a tiny turbine could drop it in under a minute.
@mipmipmipmipmip im just happy they get to spend a lot of time with their families... assuming they weren't slaving away trying to make this thing live harder than john f kennedy.
I wonder how they could overcome the possibility of a capsule stopping with another one at mega speed behind it, no views to the outside world and the possibility that once inside the tube, if trains for some reason get stuck, people would have a limited amount of air to breath in their capsulesa vacuum.
So every time you have to use this system you have to pump a vacuum.. pressurizing and depressuring causes fractures and costs a lot of energy.... While i get the idea.. it just seems to have so many flaws.

I saw a system with jetbridges to solve the problem of passengers entering or leaving the pod. But the system will be too expensive to be viable.
