=== Smart Mutex === [[File:Smartmutex.png|thumb|Smart Mutex allows two trains to pass while blocking two others]] The Smart Mutex is a mutex sign that checks the paths trains (will) take through the mutex zones, allowing trains to pass that don't have a path intersecting with one another. This allows multiple trains to cross an intersection at the same time provided they can safely pass each other.
智能闭塞区间会检测列车通过区间的路线，允许路线不互相影响的列车通过。这允许多列车同时穿过交叉路口，前提是路线不会互相影响。
