This is physical infrastructure, with a steel railroad and with railroad engines, locomotives, and cars that could do damage to themselves and other people's property if they collide, so yes, an element of coordination has to happen, as it happens now in the U.S. It actually does work.
Cependant, le principe est sensiblement le même. Il s'agit d'une infrastructure matérielle — une voie ferrée, des locomotives et des wagons qui peuvent s'endommager ou causer des dommages à la propriété d'autrui s'ils entrent en collision.
