Trains at both intersections will run correctly. They will not block the intersection and the ride will be smooth.

'''Correct use of bi-directional signals'''<br>
To prevent trains from getting stuck nose-to-nose at bi-directional signals, they have to be placed very carefully. There are basically only two situations where they should be used:
