Gated level crossings were mandatory from 1839, but initial rules were for the gates to be ordinarily kept closed across the highway. [6] The original form of road level crossing on British railways dates from 1842 onwards, [6] [7] it consisted of two or four wooden gates (one or two on each side of the railway). When open to road traffic, the ...
Level crossing signals are electronic warning devices for road vehicles at railroad level crossings. Level crossings can be operated in various ways. In some countries such as the UK, the warning devices are more often than not activated by remote control, I.e. an operator pressing buttons. However, the majority of countries have automated systems.
Irish level crossings are nearly similar to UK level crossings, in that they have a preliminary amber light before the red lights start flashing and the barriers descend. Crossings are the same on the whole island of Ireland, and are either of the old gated variant, or are automatic. Ireland has automatic crossings that have full barriers.
A level crossing is an intersection where a railway line crosses a road, path, or (in rare situations) airport runway, at the same level, [1] as opposed to the railway line crossing over or under using an overpass or tunnel.

The construction of new level crossings is generally not permitted, especially for high speed railway lines and level crossings are increasingly less common due to the increase of both road and rail traffic. [4] Efforts to remove level crossings are done in the UK by Network Rail and in Melbourne as part of the Level Crossing Removal Project.

They are used where a track circuit requires reinforcing with additional information about a train's location, such as around an automatic level crossing, or in an annunciator circuit, which sounds a warning that a train has ...
