Maintaining the 150-year-old infrastructure in London’s Underground network is no easy task. The workers at Tube Lines have to move people, equipment and materials into the tunnels each night to perform the necessary work on the Jubilee, Northern and Piccadilly Lines. They’ve only got about 4 hours to do their repairs, however, so speed is of the essence.

But safety matters too. Until recently the company’s workers had to look up proper safety protocols in a 20,000 page manual that was printed out into a bulky binder. That meant precious minutes were wasted looking up information instead of getting work done.

The solution was to switch for binders to Windows 8 mobile devices, in a way that was manageable, efficient and customised to their needs -- using the most secure tablet platform available.
