The rail industry has been around for centuries, but it is not stuck in the past. On the contrary, it is constantly evolving and adopting new technologies and innovations to improve safety, efficiency, speed, and sustainability. In this article, we will explore some of the most exciting developments that are shaping the future of rail travel.
Superfast Maglev Trains
Maglev trains are trains that use magnets to levitate above the tracks, eliminating the need for wheels and reducing friction and noise. They are currently the fastest form of rail travel in the world, reaching speeds of over 400 km/h. The Shanghai maglev train, which connects the airport to the city, is the fastest in operation, covering 30 km in just 7 minutes1.
But maglev trains are not stopping there. The next generation of maglev trains will be even faster and more efficient. For example, the Chuo Shinkansen line in Japan, which is expected to open in 2027, will use superconducting magnets to achieve a maximum speed of 505 km/h, cutting the travel time between Tokyo and Nagoya from 90 minutes to 40 minutes1. China is also developing a prototype of a super maglev train that could reach 1,000 km/h in a vacuum tube1.
Autonomous Rail
Autonomous rail is the use of artificial intelligence, sensors, and communication systems to operate trains without human intervention. Autonomous rail can enhance safety, reliability, and capacity by reducing human errors, optimizing traffic management, and increasing the frequency of trains. Autonomous rail is already in use in some urban metro systems, such as in Shanghai, Dubai, and Sao Paolo2.
However, autonomous rail is not limited to metro systems. It can also be applied to long-distance and freight trains, as well as to maintenance and inspection tasks. For example, Rio Tinto, a mining company, has deployed the world’s first fully autonomous heavy-haul rail network in Australia, which transports iron ore from mines to ports using driverless trains2. Another example is the Robel Mobile Maintenance System, which uses robots to inspect and repair rail tracks2.
Biometric and Microchip Ticketing Systems
Biometric and microchip ticketing systems are technologies that use biological or electronic features to identify and authenticate passengers, eliminating the need for physical tickets or cards. Biometric ticketing systems use facial recognition, fingerprint scanning, or iris scanning to verify passengers’ identities and grant them access to trains. Microchip ticketing systems use implanted or wearable devices, such as smart watches or rings, that communicate with readers at the stations or on the trains.
These technologies can offer several benefits for passengers and operators, such as convenience, security, and efficiency. Passengers can enjoy a seamless and contactless travel experience, without having to worry about losing or forgetting their tickets. Operators can reduce fraud, save costs, and collect valuable data on passenger behavior and preferences. Some examples of biometric and microchip ticketing systems are the FacePass system in China, which uses facial recognition to allow passengers to board trains without scanning a QR code or ID card3, and the Biohax system in Sweden, which uses microchip implants to enable passengers to pay for their journeys with a wave of their hand3.
Active Suspension Systems
Active suspension systems are systems that use sensors, actuators, and controllers to dynamically adjust the distance between the wheels and the carriage of a train, depending on the track conditions and the speed of the train. Active suspension systems can improve the ride quality, stability, and performance of trains, especially on curved tracks. They can also reduce wear and tear, noise, and energy consumption.
Active suspension systems are already in use in some high-speed trains, such as the Shinkansen E5 series in Japan, which uses air springs and dampers to control the vertical and lateral movements of the carriages2. However, active suspension systems can also be applied to conventional and metro trains, as well as to freight trains. For example, the University of Birmingham has developed a novel active suspension system that uses hydraulic actuators and a model-based controller to reduce the vibrations and sway of trains2. This system can increase the speed of trains on curved tracks by up to 13%, and reduce the energy consumption by up to 6%2.
Hydrogen Fuel Cell Trains
Hydrogen fuel cell trains are trains that use hydrogen and oxygen to produce electricity, water, and heat, without emitting any harmful pollutants. Hydrogen fuel cell trains are a green and sustainable alternative to diesel trains, which are still widely used in many parts of the world. Hydrogen fuel cell trains can offer similar performance and range as diesel trains, but with lower operating costs and maintenance requirements.
Hydrogen fuel cell trains are already in operation in some countries, such as Germany, France, and China3. The first hydrogen fuel cell train to enter commercial service was the Coradia iLint, developed by Alstom, which started running in Germany in 20183. The Coradia iLint can reach a speed of 140 km/h and travel up to 1,000 km on a single tank of hydrogen3. The hydrogen is stored in tanks on the roof of the train, and the fuel cells are located under the floor. The electricity generated by the fuel cells is used to power the electric motors that drive the wheels, and the excess electricity is stored in batteries for later use. The only emission from the train is water vapor, which is released through the exhaust pipes.
