# Level Crossing (Trummery) Order (Northern Ireland) 2004, Paragraph 12


The arrangements shall be such that the protecting railway signals can only be cleared after the barriers are fully lowered and after the ‘crossing clear’ push-button has been pressed. Unless the protecting signals have been cleared for another train, all the barriers shall rise simultaneously either after the ‘raise’ push-button has been pressed or automatically as soon as the train has passed clear of the crossing.
