History Gated level crossings were mandatory from 19, but initial rules were for the gates to be ordinarily kept closed across the highway The original form of road level crossing on British railways dates from 1842 onwards, it consisted of two or four wooden gates (one or two on each side of the railway) When open to road traffic, the gates were closed across the railway toAlso known as pedestrian user friendly intelligent crossings – these are similar to pelicans but Once the signaller or crossing keeper has pressed the 'down' or 'lower' button the sequence is fully automatic up to and including the red lights flashing, they then being able to stop the barriers from lowering by either pressing a 'Stop' button or releasing the 'Lower' button depending on crossing style, but with the red flashing lights showing
