Virgin Hyperloop Being Built in India - Looks Like a Tube of Death

I would hope there's a openable section every X number of metres.
OK but how do they get the car to that point? And how do they get you down? And how do they recover you in the middle of nowhere? lol
I think you're overthinking it. Life's dangerous and we all have to die at some point, and with climate change on the horizon, rather sooner than later.
Might as well die trapped inside an overly futuristic gizmo that doesn't serve a function, at least none that's not better met with classical public transport.
Cherrypickers and so forth I'd imagine. They'd need to invest on having it available to arrive in decent time across the line though, you're right.
Going from 3.5 hours to under 35 minutes, zero direct emissions. But yeah, better met with classical public transport.
If you were born at a different age, you would probably be saying that about horse drawn carriages.
They have to do maintenance, right? There are probably hatches or doors every certain number of sections, along with walkways or corridors within where workers can perform upkeep.
You can literally see the access ports (or at least what appears to be access points) on every section :-P
(I'm an engineering inspector..lol)
If the train had to come to an emergency stop and people needed to evacuate the train, you can see from the interior shot of the tunnel, there are walkways at either side to allow people to walk single-file down the tunnel. There probably will be an emergency exit and stairs positioned every quarter mile or so to allow people to get out.
That isn't a walkway. Those are the rails for the train.
And looking at the door for the train, unless it opens like a minivan door, I don't get how anyone is getting out of it while it's in the tunnel.
All the possible answers to these questions seem much more desirable than when the equivalent is asked of the next-fastest form of transportation.
The distance between Mumbai and Pune is roughly 150 kilometers. Taking 35 minutes to cover that distance, the average speed is 257mph. This is slightly faster than conventional trains, but not by much. The fastest conventional train in service runs at ~220mph, though the conventional speed record is 357.2 mph. This hyperloop would run at about the same speed as a maglev train (268 mph), which is at least more proven technology.
You know there are railroads without roads next to them right? Perhaps they can drive inside the tunnel in an emergency? There can be access roads at certain distances?
Also this.
They'll have emergency oxygen reserves and oxygen masks, not unlike an airplane, and they will have little backup motors and deployable wheels that will drive them to the destination or a safe point should things go awry.
Is this the near vacuum version, or the "basically a tube above ground" version?
If it's a near vacuum version I'd love to know how they've got around some of the problems.

Yeah it's much more dangerous than the current public transport in India
Weren't people clamoring for this shit in California when Elon Musk wanted to build one? Now it's actually getting done somewhere and it "doesn't serve a function"?
You know most railroads aren't stuck in an elevated tube, right?
How do you get out of a subway train? You get out, walk down the track to an entry point in the tunnel..
Supposing it has high throughput, high reliability, and manageable long-term costs, I see no issue with this. However, there have been too many failed high profile gadgetbahns for me to view this with anything more than cautious skepticism. I wholly expect this to be a waste of public resources producing an exclusive, expensive transport system for the upper class.
The Indian flag is a gorgeous thing. Surely they would have thought of all possible danger scenarios. Come on guys.
Bullet train = cutting lots of trees.
Do you ask yourself these questions when you fly in a plane over the ocean? lol
As far as I'm aware, these systems are built to operate in a vacuum. Can't really walk down the tracks.
Is hyperloop safe?
Safety is our number-one priority and we're designing hyperloop to be inherently safer and more reliable than maglev or high-speed rail. We have no at-grade crossings (by far the leading risk posed by trains), so there are no interactions with other forms of transport or wildlife. We are fully autonomous, so there is no driver related error. We are immune from most weather events. We will have multiple emergency braking techniques, triggering an immediate braking of the vehicle. Vehicles will have a full suite of life support systems, and we have the ability to re-pressurize the tube if needed. We strive to surpass the safety of all existing transport systems, and have a dedicated safety team to work with regulatory authorities to define and implement best practice safety protocols.
How is hyperloop going to get certified by safety agencies and regulators?
We realize that for this technology to be commercially viable it needs to be safe and reliable. Safety is our number-one priority and we are making sure to spend the necessary time to further develop and test our technology. While we work on our technology, we simultaneously work with governments around the world to ensure our technology is safe, regulated, and intermodal. More than two-thirds of the hyperloop systems fit under existing regulatory standards – across aerospace, rail, and automotive. But for the remaining third, we'll need a new standard. We've already begun the early stages of the certification process and look forward to continuing our work with regulators to meet existing regulations where appropriate and create new ones where needed.
What happens if there's a sudden breach in the tube?
Our tubes are constructed out of thick, strong steel and are very difficult to puncture or buckle. We're designing and constructing the tube and pods explicitly to handle down to 100 Pa of pressure or more (equivalent to air pressure at 200,000 feet above sea level), changes in air pressure, and to safely tolerate small leaks, holes, and even breaches without suffering from reduced structural integrity.
If there was a leak or breach in our tube in an operational system air would leak into the tube. The affected vehicles would slow down due to the additional air pressure, or require a power boost to get them to the next station. The pods will be built to withstand even sudden air pressure changes safely. We will also have the ability to section off parts of the route and re-pressurize sections in the case of a significant emergency. Every pod will have emergency exits if needed, but mostly pods will glide safely to the next portal (station) or egress point in the event of an emergency. Additionally, we are building sensors throughout the system to notify of any leaks or breaches and we would be able to identify and perform maintenance to resolve any leaks quickly.
I would suggest they would eliminate the vacuum issue if they needed to get people out of there.
