Vacume tube transport (Russia?)

Due to the vast distances involved, a vacume system of transport may be coming to Russia sooner than you think,  giving great speed and time savings, thus being a direct competition against domestic airflights.

Could be the future, I wonder?

That'd be the Hyperloop funded and started by Elon Musk then.

Could well be between LA and SF before Putin gets a ride.

I used to be with it, but then they changed what `it` was.
Now, what I`m with isn`t it, and what`s `it` seems weird and scary

Meanwhile all we get in the UK is 19th century twin rails, which is supposed to be capable of carrying high speed modern trains, though if a leaf gets on a rail, heaven help us 

PS...Cost is the overiding factor in the UK and is usually a poor outcome by committee. I remember back in the late seventies, I was with a consortium that wanted to bid for a new overhead monorail above the streets to replace the old Glasgow circular tube line, but renovation of the tube went ahead instead.

The monorail was the future with some stations going directly into large shops. Pity it never happened as it would have looked good.

We used to be the innovators in the UK, but sadly other countries are taking the lead in better high speed transport, where the vehicle is safely wrapped round the track or as in this case within the track, instead of the antiquated twin rail system of yesteryear.

Im in Saigon now and they are currently spending billions of dollars on an underground system here which would appear to be miles ahead of anything we have, certainly in glasgow.....i don't understand how they can afford the money here but not in the UK.....

Hyper tube and Richard Branson in the news again and looks like a go ahead to be installed in India....

Now as a Sifi fan I think it is a move to the future with very high speed train transport (estimated at 600MPH). Using maglift technology in a vacuum tube, to reduce friction.

Only downside is the vacuum tube system, assuming they can create a vacuum in such a massive volume of a tubed system,  and the dangers involved if the tube is damaged to atmosphere or train occupants exposed to the vacuum.

Any above ground system is open to the modern world of terrorism, though it could be buried. I just see such problems with the system, including terchnical problems with steel expansion and contraction with temperatures, some sort of expansion gasket system would be required.

It really sounds like the future but there are a lot of things to overcome on Security, safety and technically.

Pune to Mumbai 90 miles is now going ahead...2.5 hour car drive will now be 25 minutes by vacuum tube. (approx 200MPH)

Abu Dhabi to Dubai 80 miles is now going ahead....2 hour car drive will now be 12 to 18 minutes by vacuum tube. Depending on speed quoted. Also the diameter of the mockup train compartment here seems very large and spacious compared to previous test tracks. so would require a very large diameter tube to contain it.

1200kmh =745mph quoted in this video, the figures are not correct here...
Checking on other websites quote 500MPH maximum.
So they are going all out, and not the current 300 MPH advised restriction
WoW...Typical fast drivers in the Middle East :D



Other systems on the cards, of interest to us....

Based on current 300mph advised restriction on speed (being new technology/first test tracks) would be...
Sydney to Melbourne 400 miles 300mph = 1.33 hours  (1 hr 20 min)
Glasgow to Liverpool 200 miles 300mph =  0.66 hours (40 min)
Edinburgh to London 500 miles 300mph =  1.66 hours (1 hr 40 min)
These times will decrease if higher speeds are allowed at later date.
Also many USA routes and other world routes being considered.

There is always critics of new technology, myself included as an engineer we always have to question our designs, and ensure the best solutions for efficiency and safety.

Although i love the idea of fast transport for the masses,  which may be even safer that airplane travel. Here we have a guy busting the hyperloop idea, due mainly to vacuum seal problems with thermal expansion due to sun and weather, and even creating the vacuum in the first place for a tube of such length.

I have not seen any data on solutions, but like an oil pipeline that has pumping stations every so often, I would think they would have to segmented sections of tube with opening doors that have vacuum pumping for that specific section. There would be dangers in that if a vacuum door did not open in sequence before the train reached it ...BANG!, so safety systems would have to be very strict.

Here is the Hyperloop busted video, and see what you think.....
