Rail collision avoidance systems need to detect cars not trains
The German Aerospace Centre (DLR) has developed a system to prevent trains colliding with each other. Each train would carry a radio system: as soon as two trains were within radio range of each other, they would exchange information about their position, speed, loading gauge and planned route. If the system detected a potential collision, drivers would be warned.
The system is seen as a backup to existing signalling systems.
For details, see the DLR website
Collisions between trains do happen - notably, just outside Brussels earlier this year. But because of a fail-safe signalling system, disciplined and well-trained drivers and 175 years of learning from accidents, they don't happen often.
Sadly, far and away the most common collision is between a train and a vehicle on a level crossing. Something which could detect THAT and warn train drivers in advance really would be valuable.
Either that or an injection of that rare commodity, common sense, into the heads of all road vehicle drivers!
