  2. Level crossing signals - Wikipedia

    en.wikipedia.org/wiki/Level_crossing_signals

    The time interval may be controlled by a level crossing predictor, an electronic device which is connected to the rails of a railroad track, and activates the crossing's warning devices (lights, bells, gates, etc.) at a consistent interval prior to the arrival of a train at a level crossing. [1]

  3. Level crossing - Wikipedia

    en.wikipedia.org/wiki/Level_crossing

    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 or the road etc. crossing over or under using an overpass or tunnel.

  4. Level crossings by country - Wikipedia

    en.wikipedia.org/wiki/Level_crossings_by_country

    In Norway, level crossings have crossbucks colored in a white background with a red border, with similar lights to the German crossings, although the white light flash when the crossing is clear, instead of a yellow warning light, and the red light flashes, as do the lights on the barriers.

    After the Ufton Nervet rail crash, there have been increased efforts to review the placing of level crossings and to eliminate them where this is practicable.In the UK it has also been suggested that cameras similar to the type used to detect drivers who run traffic lights be deployed at level crossings, and that penalties for ignoring signals should be much more severe.

    Isolated control is where the timings of the junction or crossing are not linked to any other junctions or crossing. Failures: If power is still available, a flashing amber light is used to warn of an intersection. Methods to distinguish the main road from the secondary road (and hence right of way) include using yield (give way) signs, stop ...

  7. Polish railway signalling - Wikipedia

    en.wikipedia.org/wiki/Polish_railway_signalling

    Normally, level crossing warning signals display no aspect (i.e. are unlit). They light up in the front of an approaching train which is the first clue that the system is working correctly. Level crossing warning signals are unrelated to other signals, therefore in case of Osp1 signal a train must proceed at 20 km/h regardless the higher speed ...

  8. Level junction - Wikipedia

    en.wikipedia.org/wiki/Level_junction

    A level junction (or in the United Kingdom a flat crossing) is a railway junction that has a track configuration in which merging or crossing railroad lines provide track connections with each other that require trains to cross over in front of opposing traffic at grade (i.e. on the level).

  9. Crossbuck - Wikipedia

    en.wikipedia.org/wiki/Crossbuck

    In contrast to the American "railroad crossing", Australian signs say "railway crossing" or "tramway crossing". (Most cases where a tram in its own right-of-way crosses a road do not use a crossbuck and so are regular intersections rather than level crossings.) Different countries may classify the sign differently.
