Then every vehicle that crosses the border on the railway, including the locomotive, gets “VACIS-ed”, if I may turn that noun into a verb. It then is inspected to see what is in that container, that railway car—to see whether there are bad things in there or bad people in there.
Ensuite, chaque véhicule qui franchit la frontière, y compris la locomotive, est passé au VACIS, puis inspecté pour voir le contenu du conteneur ou de wagon pour voir s'il contient des choses ou des personnes illicites.
