Trains

The world's largest rail vehicle manufacturer has rolled out a zero-emissions train running on hydrogen fuel cells with a supercapacitor buffer. The four-car train is capable of 100 mph (160 km/h), making it the fastest hydrogen train to date.

If you want to maximize the number of trains that can operate on one line simultaneously, it's crucial that you know the exact location of each train at all times. A new system is designed to help, by analyzing the magnetic properties of the rails.

Four years after embarking on a two-year operational trial run in Germany, a bunch of Coradia iLint hydrogen fuel-cell trains have entered passenger service along a 100% hydrogen route in Lower Saxony.

We're seeing a growing emphasis on direct air capture technology in our efforts to combat climate change, and an interesting new take on this technology could see it put to use on railways around the world.

Australian mining company Fortescue has acquired Williams Advanced Engineering, and announced the two companies' first joint green-tech project: a battery-electric "Infinity Train" that'll haul iron ore without ever needing to plug in or fuel up.

Why bother transferring between a bus and a train, if you could just stay in one vehicle that travels on both roads and tracks? That's the thinking behind a new dual-mode vehicle (DMV), which is slated to begin operations in Japan on December 25.

Diesel-electric locomotives can be easily converted to battery-electric, says a new paper in Nature Energy, at a 20-year cost that can beat parity if emissions costs are taken into account. And there will be other benefits, notably for the power grid.

While the inspection of railway tracks is an important task, such inspections have to be performed when no trains are nearby. The new rail-riding Staaker BG-300 Railway Drone offers an alternative, as it just flies off the tracks as trains approach.

China has produced the first of a new breed of maglev trains capable of speeds up to 600 km/h, or nearly half the speed of sound. It says these will be the fastest ground transport services available on the planet.

As it eyes the future of sustainable transport through the development of advanced batteries and hydrogen fuel cell technologies, General Motors is now expanding these ambitions to include the world of freight.

Rail technology company Wabtec has demonstrated a new form of electric train technology that could help lessen the environmental footprint of heavy-haul freight services, reducing fuel consumption of an entire train by 11 percent in an early pilot.

Earlier in the year, LG Display showed its vision for the aircraft cabin of the future, which included transparent OLED partitions. Now the company has installed the technology in subway train windows.
