Train-kilometre

Unit of measurement representing the movement of a train (see A.IV-05) over one kilometre. The distance to be considered is the distance actually travelled. When a breakdown of the traffic in train-kilometre is requested by type of train without ‘mixed’ as a category, and when mixed trains cannot be classified in either the passenger transport or freight transport category, the train-kilometres travelled by them are computed separately and subsequently allocated according to one of the following methods classified by order of preference: - proportionately to the passenger and freight gross hauled tonne-kilometre (see A.IV-14); - proportionately to the passenger and freight vehicles or axle-kilometre; - according to fixed coefficients.
