Next-gen London underground display

Below is a mockup of my fantasy next-generation London underground on-platform display, which would not only show you exactly where incoming trains were on the line (and update their progress in real time), but also which carriages were more or less crowded (achieved by sensing passenger body heat or possibly carriage weight, to account for all those suitcases). That way, you could increase your chances of boarding and the platform announcers wouldn't have to keep telling new arrivals to move along the platform.

Go on TfL/CBS Outdoor - you've already got the screens...
