Artikel 1

1. On every railway line carrying a considerable volume of international traffic, which crosses the frontier between two adjoining countries, the competent authorities of those countries shall, wherever examination cannot be satisfactorily carried out while the trains are in motion, jointly examine the possibility of designating by agreement a station close to the frontier, at which shall be carried out the examinations required under the legislation of the two countries in respect of the entry and exit of passengers and their baggage.
2. Where two adjoining countries designate several stations of this kind along their common frontier, the number of such stations on either side of the frontier shall, so far as possible, be equal.
