1 week agoTron on the Tube: London Underground's new trains are being tested on the Piccadilly line
The new trains are the first of a fleet of 94 new trains being built in Yorkshire at the moment, and will eventually replace the Piccadilly line's existing 50-year old rolling stock. However, before passengers can ride the new trains, they need hundreds of hours of testing and assurance that they will work as expected. And testing has been underway ever since the first train arrived in London last year.
