Mac's RFID lab on track to saving subway workers' lives

Radio frequency technology developed in a partnership between McMaster University and Bombardier and aimed at saving lives on subway tracks is now ready for sale. The project team is on the road in Atlanta this week demonstrating the technology to transit authorities, hoping to find a buyer.

Final testing is still under way on TrackSafe, which uses radio frequency identification tags worn by track workers to offer warning when trains are approaching. An alert is also issued to the train operator.
