	The mutex sign handles mutual exclusion: it blocks trains ~~from~~ entering while another train is already inside ~~the zone~~. Once the zone is freed up again, the waiting trains are allowed to continue movement. This sign is useful in combination with switcher signs to avoid crashing trains. Levers attached to the base block are toggled while a train is inside the mutex zone.		The mutex sign handles mutual exclusion: it blocks trains entering a zone while another train is already inside.
