London (CNN) -- Close one eye, and it could almost -- almost -- pass for a regular underground train. Close the other, and it looks like a space shuttle from Star Trek.
The truth is somewhere in between. This is the long-awaited new Tube train for London, which features driverless technology, a single "walk-through" interior rather than individual carriages, and advanced air-cooling systems hidden behind the walls.
But it's not all change: the design includes the traditional London Underground colors and typography, as well as seats and interiors that are comfortably familiar.
"London's Tube is one of the most iconic trains in the world," says Paul Priestman, Director of Priestmangoode, the agency that designed the train.
"We are proud to have designed something that it is part of the very fabric of London life, celebrating all that's great about London's environment: cutting edge technology, rich history and diversity."
