On average, there is a level crossing each 2 kilometres (1.2 mi). [43] [44] An emergency button is installed on every level crossing in the country, allowing members of the public to report emergencies at a crossing to authorities, such as stalled vehicles or other obstacles. [45]
Each Landau level is degenerate because of the second quantum number , which can take the values =, where is an integer. The allowed values of N {\displaystyle N} are further restricted by the condition that the center of force of the oscillator, x 0 {\displaystyle x_{0}} , must physically lie within the system, 0 ≤ x 0 < L x {\displaystyle 0 ...
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]

Following the 1920s and 1930s, when custom-built bodies were available with a split front and rear roof design, the use of landau changed from a functional feature on limited production cars to of a decorative feature in some higher market segment production cars. [11] The term landau fell into disuse from the mid-1940s until the late-1950s. [12]

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.
