Thanks to London, we have all seen how effective underground railways can be. The London underground rail track was however done around the 1860s. As the world grows in population, solutions are needed for the vibrant sustainability of population needs. These needs include traffic management and alternative solutions to on-surface routes. Let’s have a glimpse at the future and plans in place for the Hyperloops and Underground Tunnels modes of transportation. 

Understanding the Underground Tunnel Transportation

Underground tunnel transportation involves moving people and goods through tunnels below the earth’s surface. This concept began in 1863 with London’s Metropolitan Railway, the world’s first underground line, designed to reduce street-level congestion. Today, it has evolved with more advanced technologies, including hyperloops and subterranean roads.

Underground travel uses tunnels for various vehicles, from traditional trains to innovative systems like the hyperloop. Which moves pods at high speeds through vacuum-sealed tubes. This mode of transport is particularly appealing in urban areas, where above-ground space is limited and traffic congestion is severe.

The benefits of underground transportation include increased safety from reduced potential for accidents, faster travel times free from surface barriers, and lower traffic congestion. However, challenges like high construction costs, environmental disruption during tunneling, and potential pollution issues remain. 

Elon Musk’s Boring Company is exploring new possibilities in this field. By creating tunnel networks for electric vehicles, aiming to simplify urban travel. An example is the LVCC Loop in Las Vegas, a system designed to transport people quickly during large events.

As technology advances, the implementation of these systems could become more practical. Also could become widespread, potentially transforming how we think about city travel.

What are Hyperloops?

Hyperloop is an innovative transportation system envisioned to drastically reduce travel time over long distances. Originally conceptualized by Elon Musk in 2013, the hyperloop proposes transporting passengers and freight in pods that speed through low-pressure tubes. The pods are designed to either float using air skis. Like an air hockey table, or through magnetic levitation. Minimizing friction and allowing speeds of up to 750 miles per hour.

The system operates by enclosing the pods in tubes from which most of the air has been removed. This design reduces air resistance, enabling the pods to achieve high speeds efficiently. Musk imagined the hyperloop as a “fifth mode of transport,” different from traditional trains. This is due to its high speed and the technology used to minimize travel resistance.

One of the major advantages of the hyperloop is its potential to be faster and less expensive than cars and trains. Also less polluting than airplanes. The idea is that hyperloop could ease congestion on busy roads. Providing significant economic benefits by improving connectivity between cities.

In practice, prototypes and developments in hyperloop technology have shown varying degrees of success. For instance, a team from the Technical University of Munich set a speed record for a hyperloop pod at 288 mph. However, challenges remain, including high development costs and technological hurdles. The high development cost and not much funding had driven out companies like HyperloopOne. Despite these challenges, the hyperloop remains a compelling concept for the future of transportation. It promises ultra-fast, efficient, and sustainable travel.

Engineering Behind Hyperloops and Underground Tunnels

Hyperloops and underground tunnels are designed with sophisticated technologies that maximize speed and efficiency while minimizing friction and air resistance.

Hyperloop systems work by propelling pods through low-pressure tubes, significantly reducing air resistance. The core principle is similar to vactrains, but Hyperloop operates at approximately one millibar of pressure, which is significantly lower than atmospheric pressure. This partial vacuum is necessary because it allows the pods to travel at high speeds while minimizing aerodynamic drag.

The pods are designed to levitate with air-caster “skis.” These skis use a thin cushion of air, supplied under pressure, to lift the pod off the tube surface.

Airflow is managed at the front of each pod by an electrically driven inlet fan and an axial compressor. They direct high-pressure air from the front, where it tends to accumulate and slow the pod, to the back. This mechanism not only helps to maintain speed but also provides the necessary lift by directing some of the high-pressure air to the air-caster skis.

Challenges and Safety Concerns with the Hyperloop Underground Tunnel

One of the primary challenges in Hyperloop technology is maintaining a low-pressure environment over long distances, which is critical for reducing air resistance. Also, maintaining the tube’s structural integrity against external and internal pressures is critical, especially as the system expands to accommodate longer routes.

Tunneling techniques must consider geological variables, environmental impact, and urban infrastructure. Further, the integration of tunnel systems with Hyperloop technology must ensure that the capsule’s inner surfaces are smooth to maintain high speeds.

The design prioritizes passenger comfort despite high speeds. The projected maximum inertial acceleration within the pods is around 0.5 g. This is manageable for human passengers and comparable to the experience of a commercial airliner during takeoff and landing. Providing such comfort while reaching speeds of up to 760 mph demonstrates the delicate balance of aerodynamics and engineering in Hyperloop systems

What are the Active Hyperloops and Tunnel transports in the World in 2024?

There are different ongoing projects around the world for the hyperloop and underground tunnel transportation. The two most prominent ones that will soon (or currently) be widely active are the Vegas Loop by The Boring Company and the European Hyperloop Initiatives.
