Meaning of half-barrier | Babel Free

Definitions

At an automatic half-barrier level crossing, a lifting barrier that does not block the whole road when in the horizontal position, placed on the left side in the UK according to driving on the left, and mostly used on narrower or quieter roads instead of two lifting barriers either side of the railway crossing.

Examples

“[...] all crossings with lifting half-barriers will be equipped in this way. [...]. At level crossings where there are to be half-barriers, train-operated through track-circuiting, the barriers will be timed to lower fully about five seconds before the fastest train can reach the crossing.”
