摘要

The system has a barrier and a detector (3). The barrier has a panel (5) pivotable with respect to a mast (4) containing a controller (6) for opening and closing the panel and the detector is coupled to the controller so that when a tram is detected the panel is automatically opened. A remote controller coupled to the controller has a separately operated remote control device (7) for a security post.
