London is implementing driverless trains in the Tube

London is getting ready to welcome new Tube trains for the next 40 years. Last week, London unveiled the new cars to the public for the first time, and when the trains finally hit the tracks starting in the mid-2020s, they’ll bring an appreciable list of improvements to riders. With the new design, you’ll be able to walk the entire length of the train, which frees up lots of space that was wasted just from closing off individual cars in the past.
