FAQ
The minimum traffic interval is based on the applicable requirements that ensure a necessary level of safety. On the one hand, by the on-line traffic speed, and on the other hand, by the length of the station platform and the time of embarkation and disembarkation of passengers. For single uPods this interval is 25-30 seconds. uPods that are electronically coupled in a train can leave the station one after another with a minimum interval of 2-3 seconds (this is, for example, the interval of cars on the autobahn).
uST Transport & Infrastructure Complex can operate 24/7 on intercity lines (as on railroad) and 20/7 on city lines (as in subway).
Yes, they are GoA4 in the grade of automation (IEC 62290‐1) – unmanned, with central control.
uPods can be located both in special holding stations (“parking lots”) and on the spare lines of stations and in the garages with repair shops (depending on the performance of uST Transport & Infrastructure Complex). During off-peak hours, electric rail cars, if necessary, are removed from the line with the help of appropriate infrastructure components and placed in special holding stations or in service and repair areas.
There are no structural limitation, and the only one is the vertical curvature radius of the track over the support, which determines centrifugal accelerations (no more than 1 m/s2), and thus the comfort for passengers when passing a support. For instance, for a speed of 500 km/h, both horizontal and vertical track curvature radii (including on supports) must be at least 20,000 meters. The combination of structural solutions in uST string rail overpass and rolling stock includes the support saddle, high bending stiffness of the track structure, highly tensioned holding rope, and pneumatic suspension of the wheels, which ensures any required traveling smoothness of uPods, including when passing a support. If necessary, the support section can have reverse curvature of the track (concave curve with bending in the middle of a span), that is the passenger not only will not feel overloads, but on the contrary, his weight will decrease to some extent when passing a support.
Unfortunately, you cannot be 100% sure to guarantee that any component will not fail. However, so far, we have not yet recorded a single malfunction in power supply. The onboard traction electric drive is equipped with a mature cooling system that has independent loops, the products are tested in climatic chamber, the tropical uCar has been successfully operated in the UAE for more than three years already.
We should also highlight that a failure of the traction power supply (e.g., electric substation) will not stop the traffic on the line. Even a failed part of the electric drive system won’t stop the complex, as each system in it is duplicated. Besides, if there are any power supply problems on rails, the onboard emergency battery of uPod will produce enough power for at least 100 km of journey.
Yes, uPod can move at the same speed in reverse direction as a shuttle. The movement direction of the rolling stock is determined by the design of the undercarriage, suspension systems, traction electric drive control systems and the external contours of the body. The main types of uPods will be operated without any reference to directionality, as this solution is universal, which also allows reducing the operating costs. At the same time, of course, there are also solutions with unidirectional movement, which is a priority in a number of projects, especially with large passenger and cargo flows.
uST Transport & Infrastructure Complex can be designed both for operation in freezing climate (down to -60 °C) and for in tropical conditions (+50 °C with extension of operating temperature up to +55 °C).
Today, string transport is operated both in temperate climate (the bottom temperature limit is -40 °C in Belarus) and in the tropics (up to +55 °C in the UAE).
As for rainfall, uPods are undergo sprinkling tests with rainfall intensity of at least 2-3 mm per minute, which corresponds to a heavy tropical downpour.
Humidity is up to 100% inclusive under appropriate conditions of the climatic region.
Wind stability for the complex to operate in a standard version is 90 km/h (25 m/s). Anything higher – up to 250 km/h (70 m/s) – is possible in a special version based on customer requirements.
Probably. Our uPods are prepared and already operated in harsh conditions, including sandstorms, in Sharjah (UAE). The possibility of operation is ensured by a number of structural solutions in the infrastructure components of the string rail overpass, rolling stock, including a mature filtration system and installation of various cleaning systems. Such systems include, for example, a device to clean the rolling surface of the rail from stuck sand or the traction module blowing system.
Prestressed strings are elements in which tensile stress state is created in various ways, so in its design essence it is a prestressed bearing reinforcement. The company mainly uses reinforcing ropes.
The vertical load is distributed to supporting towers, installed at intervals of up to 2 km. The string rail track structure looks light and delicate: it does not block the sky and preserves natural landscapes along the route of laying tracks.
The strength of a string rail in such structures is ensured by choosing materials with certain strength characteristics, selecting the necessary rigidity and creating a tensile prestress state, which holds the superstructure.
- Flexible – standard payloads up to 20 tons, speeds up to 150 km/h and long spans up to 2 km that can reach up to 5 km when using composite strings, such as carbon fiber.
- Rigid – maximum payload up to 100 tons, high-speed modes up to 500 km/h, short spans up to 60 m.
- Semi-rigid – increased payload up to 30 tons, speeds up to 350 km/h, short spans up to 60 m.
- Semi-flexible – a combination of semi-rigid and flexible – increased payload up to 50 tons, high-speed modes up to 500 km/h and long spans up to 2 km that can reach up to 5 km when using composite strings.
The most material-intensive and expensive overpass of the listed ones is rigid, while the lightest and most inexpensive is flexible.
The energy consumption of uPods is 2–3 times lower than in traditional modes of transport using steel wheels or a magnetic cushion. If we compare this figure with road transport, including a traditional electric car on pneumatic tires, then it is 5–7 times lower.
Conventional electric vehicles use pneumatic tires, which, when worn together with asphalt, emit soot, benzopyrene, phenols and other carcinogens (more than 100 of them) into the air, while some carcinogens are contained here in greater quantities than in automobile exhaust. At UST Inc. this problem is solved due to the use of steel wheels of a special design – more efficient, for example, in comparison with railway wheelsets.
A uPod is more environmentally friendly than a traditional electric vehicle, which consumes several times more electricity and takes up space on a city road, which leads to traffic jams in which toxic substances are released. uST vehicles move above the ground and eliminate the problem of traffic jams.
Noise and vibration from uST transport is significantly lower than from a railway, tram or monorail. It has already been studied that, for example, in the Moscow metro, the presence of a passenger will be safe only for the first three seconds. Further, negative factors begin to affect the human body – an isolated and compressed space, powerful electromagnetic radiation, as well as the strongest noise and vibration. While uPods do not have even a small share of such a negative impact on a person.
uPods, including those assembled into trains, can have different capacities – from 2 to 250 passengers. Their design is separate modules, combined into a composition through a rigid or electronic coupling. Such a train is capable of transporting up to 50 thousand people per hour, that is, at the level of the metro and the railway. The number of sections and their capacity depends on the passenger flow. The uPod is driven by a traction electric drive. Speed and route control are provided by automated control systems.
uST transport can carry different types of cargo: bulk, liquid, piece, special, as well as sea containers with a nominal length of 20 and 40 feet. Their loading and unloading occurs automatically. Speed and route control are provided by automated control systems. Cargo transport is capable of carrying up to 100 million tons of cargo per year.
The string rail overpass is located above the ground, so collisions with ground vehicles (buses, cars or agricultural machinery), pedestrians or animals are impossible. The prestressed track structure maintains the operability of the uST complexes even if one or more supporting towers are damaged in the event of natural disasters or other force majeure circumstances. In such a situation, the string rails will sag more, but they will not break and their performance will not be impaired. The collapse of the track structure is also excluded in case of damage and rupture of individual strings (up to 50% of their total number), for example, as a result of a terrorist act.
Features of the uST transport and infrastructure complex elements make it possible to use it in regions with difficult climatic conditions. Pre-tensioning of rails solves the problem of temperature deformations and allows transport to operate at abnormally high and low temperatures.
The change in the characteristics of the rails under the influence of temperature is included in the project so that it does not affect the performance of the uST complexes, as well as the speed limits and the comfort of transportation. When the temperature changes, the length of the string rail does not change – the structure is prestressed and only the tensile stresses in the rail change, which ultimately makes it possible to abandon the expansion joints that affect the performance properties. The safety margin of strings is such that they will be broken only if they are cooled to the temperature of liquid nitrogen – about −200 °C.
The uST transport overpass in terrestrial conditions is designed for a temperature difference of 120 °C: from −60 °C to +60 °C. It is resistant to snow drifts up to 10 m high, icing and sandstorms, floods up to 10 m high and tsunamis, heavy rains and fogs, storm winds up to 250 km/h, earthquakes of 9 points on the Richter scale and other extreme impacts, including vandalism and terrorist acts, if such impacts are considered probable in the project, even with a probability of once in 100 years.
Control systems for uST transport and infrastructure complexes are automated. Using the technical vision of the uPod onboard control system, they continuously read information from the track structure, monitor the fulfillment of the route task, and also instantly respond to obstacles and threats. Their task is to ensure comfortable and safe transportation of passengers, as well as reliable and trouble-free transportation of goods.
The systems receive, process and analyze information thanks to sensors and fully control the route and speed of movement, independently make decisions to reduce speed or stop if obstacles are detected on the route. It provides for real-time data exchange with elements of the transport and infrastructure complex, as well as obtaining up-to-date information from other uPods.
Automated systems provide control over the state of safety in the uPod cabin and coordinate the processes of embarkation and disembarkation of passengers. The systems are able to recognize the actions of passengers that may pose a safety risk and take measures to prevent dangerous situations. For example, acts of terrorism and vandalism.
The number of personnel required to maintain the operation of the complex is determined individually for each project, but it is much less than, for example, on a traditional railway or on high-speed roads with a magnetic cushion. uST facilities need mechanical engineers, telemetry and communications engineers, locksmiths, mechanics, security guards, and other traditional professionals.
The costs for the construction of a specific uST transport and infrastructure complex depend on the planned volume of traffic, estimated speeds, the nature of the terrain and climatic conditions, the type of logistics tasks and, accordingly, the design option. At the same time, factors such as the total length of the route are important (the longer it is, the cheaper the subsequent kilometers), the terrain (plain, sea shelf, foothills, mountains), the height of the supports (the higher the path is placed, the more expensive it is), the strength of the underlying soil (sand, rocky soil, swamp), the presence of obstacles (rivers, lakes, gorges), etc.
Compared to existing overpass transport solutions (monorail, cable car, light rail transport, high-speed tram, metro, etc.), the cost of construction and operation of uST complexes is several times lower, primarily due to a decrease in the material consumption of all elements of the complex, as well as due to reducing the construction complexity. In the production of rolling stock, i.e. rail electric vehicles on steel wheels, a small consumption of structural materials is also required. The absence of massive drives, powerful frames, heavy undercarriages and wheelsets significantly reduces the cost of rolling stock production.
Resistance to external influences and durability of the string rail overpass provide low operating costs. Regular replacement of the complex elements is not required, while service intervals are significantly increased in time and mileage. The service life of the overpass before overhaul is from 50 years, while for the rolling stock this figure is from 25 years.
Maintenance of the transport complex requires work on pre-trip inspection of rolling stock and interval inspection of track structures by automatic devices as well as periodic testing of the control system with related subsystems.
It is easier to integrate a string rail overpass into an already formed urban environment than to build a new metro, railway or highway. The light string rail track will harmoniously fit into the architecture of any settlement, cross city streets, roads and rivers, and, if necessary, pass over parks and low-rise buildings. Existing communication networks can be integrated into the transport overpass, no radical re-planning of the city infrastructure is required. Passenger stations are combined with anchoring structures. Stations can be used as commercial real estate, placing cafes, shopping and entertainment centers, hotels, pharmacies and other facilities in them. Stations can also be used as additional advertising space. Due to this, the payback period of uST complexes is reduced.
The capacity required to power uST systems varies by project. Depending on the logistics, the number of stations, length of the complex, passenger traffic, traffic speeds, and power consumption will be determined. In any case, uPod fleet, with similar transport work, will require approximately 5 times less primary energy (starting from fuel combustion in a power plant) than, for example, a Tesla electric vehicle fleet.
Therefore, uST is the “greenest” transport of all possible, including in comparison with traditional electric vehicles and magnetic levitation trains.
Transport and infrastructure complexes of Unitsky String Technologies are characterized by almost zero environmental impact and low noise level. Electric rail vehicles on steel wheels run on the most environmentally friendly form of energy – electricity. Transport should peacefully coexist with nature, and not be at enmity with it, complement it, but not replace it – this is the approach the company adheres to when developing its solutions.
Ecologically clean string rail roads are dotted on the ground. This advantage, with the widespread use of transport and infrastructure complexes, can save vast territories for land users, which would otherwise be occupied by traditional transport communications. For example, under roads and railways, soils which area is five times bigger than the territory of Great Britain have already been destroyed on the planet. Vegetation will remain in the areas saved by uST, annually replenishing the atmosphere with billions of tons of life-giving oxygen. The severity of environmental pollution problems will then decrease to a safe level.
UST Inc. is an engineering company primarily that has the status of a scientific organization in Belarus. Our employees are involved in the development, production, service, testing and marketing of our uST transport and infrastructure complexes. The company is developing due to its investors who believe in technology and its scaling, launching global projects in different countries and continents. They do not invest directly, but through special crowdfunding platforms.
The competitors of UST Inc. are transport systems of the “second level” above ground, such as cable cars, light rail transport, elevated and underground metro, monorail, trains on a magnetic or air cushion. The main advantage of uST is the significantly lower cost of the transport and infrastructure complex with lower operating and transportation costs.
Any transport is created for the sole purpose of providing a transport service, where the following criteria are decisive: the cost of service, the safety of service, the availability of the service (in time and space), its comfort, energy efficiency, resource intensity, environmental friendliness, etc. As for the complex of these parameters, so and for some of them, uST has no equal among the listed and promising competitors. Behind this are not emotions, but the laws of physics.
