Eye in the sky
Satellite navigation for U.K. trains is under consideration by the rail industry. Tracking trains from space would make it possible to know where every train in the country is at any time, preventing collisions and lessening congestion delays.
They've been trying to do something similar with New York's notoriously bunchy buses, but the tall buildings have made it hard for to transmit accurate signals.

I understand that, if (and it's not likely in anything but the long term) such a system is implemented, it will be based around the European Galileo satnav rather than the older GPS.
Galileo is designed (their web site tells me) to cope with uban areas unlike GPS or GLOSNAS.
