Trains fail safe. If you cut the power to the wheels and apply the brakes, it will be inconvenient, but generally fine. Planes by their nature fail unsafe: if you cut the power they fall out of the sky and crash. So it's more difficult to design a signalling system for planes. Still, the idea seems good: couldn't we have a system that detects if the runway is occupied and broadcasts that information on ILS?
