Artikel 35

1. The gates and half-gates of level-crossings shall be clearly marked in alternate stripes of red and white, red and yellow, black and white, or black and yellow. They may, however, be coloured white or yellow only, provided that a large red disc is displayed at the centre.
2. At all level-crossings which have neither gates nor half-gates there shall be placed, in the immediate vicinity of the railway line, sign A, 28 as described in Annex 1, section A. If there is a light signal giving warning of the approach of trains or sign B, 2 ‘STOP’, sign A, 28 shall be placed on the same support as the light signal or sign B, 2. Placing of sign A, 28 is not mandatory at:
(a) An intersection between a road and a railway track at which rail traffic proceeds very slowly and road traffic is regulated by a railwayman making the necessary hand signals; or
(b) An intersection between a railway track and either an earth-track (dirt road) where traffic is very light, or a footpath.
