An even faster alternative is being developed with Hyperloop, a mode of transport that uses pods travelling through low-pressure (near-vacuum) tubes. Whilst the idea of travelling through frictionless vacuum tubes is a century old, it is entrepreneur Elon Musk (known for his ventures PayPal, Tesla and SpaceX) who is behind the current developments. Making the design open source and holding initial competitions have spurned collaborative efforts into developing the technology – for example Hyperloop Transportation Technologies draws on over 600 team members across the world from R&D and commercial partners, whilst Hyperloop One was the first company to test a full-scale Hyperloop in 2017 involving all combined components (Kobie 2017b). Both companies have proposed routes across the world with planned speeds of up to 700 mph. Building these would require less ground space than high-speed railway lines, run on less energy and thus provide savings of both cost and time (Field 2017).

Another important example is hyperloop, sponsored by Elon Musk (Virgin Hyperloop 2019). Now this rather a theory, but with possibilities for becoming real in the future. Hyperloop is a train traveling with the speed around 700 mph in a tube in a vacuum. Wherever possible it is supposed to be powered by renewables, like solar installations covering the whole top of the tube.

Hyperloop is a faster and greener mode of transportation conceptualized by Elon Musk at SpaceX (SpaceX, 2013). It describes a feasible solution for achieving near-sonic speeds at ground level. Hyperloop consists of pods travelling in a low-pressure tube, accelerated by linear induction motors and gliding over a cushion of air. Figure 34.1 depicts the design of the hyperloop system. Solar panels on the tube can generate energy much more than the operating requirement of the system (SpaceX, 2013), and hence it produces an extremely low carbon footprint which is calculated to be 5 to 6 times lesser than air travel and 2 to 3 times lesser than railways (Taylor et al., 2016). This makes hyperloop a worthy competitor for mainstream transportation systems of the future, especially in the environment of smart cities.
Can hyperloops substitute high speed rails in the future?

While High-speed rails are being used by passengers in numerous European and Asian countries, Hyperloop services are emerging and are expected to operate in the forthcoming years. Hyperloop is based on the Maglev system, which utilizes magnetic properties to propel a pod towards its destination in a vacuum at high speeds. This eliminates the use of wheels in pods and thereby removing any friction from the track (Abdelrahman et al., 2017). In terms of operation, Hyperloops are comparable to a subway system but have fewer stops within a city. A typical Hyperloop system would have passenger capsules going in either direction inside two tubes of diameter 2.23 m. A pod would travel at a maximum speed of 750 mph and accommodate 28 passengers (Dudnikov, 2017; Rajendran & Harper, 2020). In contrast, a subway car has a capacity of approximately 54 seated commuters (Rajendran & Harper, 2020).

These days, high-speed trains with more than 200 km/h transport passengers and goods worldwide. Recently, a pilot of a new generation of rail transportation fleet called Hyperloop with a speed of 1220 km/h has been implemented. Such high speeds trains will require comprehensive research to control the stability of the path and the number of differential settlements. Placing a pile below the train tracks is one way to decrease these settlements. However, when the thickness of the loose layer of the soil is high, especially on the train track, which requires settlement control at a long distance, there is no economic justification, and it is almost impossible to reduce the settlement to zero under such conditions. Control of the differential settlements of the path is essential in designing the high-speed rail lines to avoid train derailment and keep passengers safe because even the slightest movement can cause irreparable damage. Special measures should be taken to quality control of soil improvement methods. The soil improvement methods depend on different factors such as train speed, type of soil, embankment height, and thickness of soft and loose sediments. The soil under the railway embankment is improved by several techniques such as deep soil mixing, geosynthetics, stone columns, and concrete piles methods.
Hyperloop transport technology assessment and system analysis
Published in Transportation Planning and Technology, 2020
The propulsion of Hyperloop in the vacuumed tubes would be by external linear electric motor that provides a periodic re-boost every 70 miles (Musk 2013). An electric compressor fan mounted on the nose of the pod would actively transfer high pressure air from the front to the rear of the vessel and simultaneously create levitation, as well as air suspension when travelling at very high speed. The energy required to power the rotor on board the vehicles and the compressor of the fan is to be transmitted via a discrete magnetic linear accelerator affixed to various stations along the tube. The design and control of the proposed discrete long stator linear motor pushers in the vacuum tube, of the fan and compressor on board the vacuum sealed Hyperloop capsules still need to be developed, tested and proven experimentally.
