China has been working on a next-gen subway train that’s lighter, faster and high-tech. Now it’s getting a trial run in Guangzhou.
The Guangzhou government says the new train can reach speeds of 140 kilometers per hour (87 miles per hour), which is 75% faster than current subway trains. This is because it’s made of carbon fiber composite, making it 13% lighter. It’s also 15% more efficient thanks to the addition of a silicon carbide inverter and permanent magnet synchronous motor.

But the train isn’t just faster. It includes high-tech upgrades like translucent touch-panels for windows, although it’s not yet known what those touch-enabled windows will be used for.

The trains are also said to have better sound insulation that will reduce the noise in the cars by more than five decibels.
