1.1 - Multiple wagons
A wagon composed of permanently-coupled units, or multiple wagon, is a combination formed by
several frame-bodies, each of which is equipped with running gear permitting it to be moved
individually, for example, on a workshop track.
This combination is provided at the two ends with draw and buffer gear of the conventional type
(according to UIC Leaflets 520 and 526-1 - see Bibliography - page 11). Coupling between units is
obtained by means of special components which cannot be separated in normal operations.
A multiple wagon can be formed either from 2-axle vehicles or from bogie vehicles.
When the wagon is composed of two units, it is called a couple.
1.2- Articulated wagon
An articulated wagon is a wagon formed from units connected to one another by an articulation
arranged at right angles with the intermediate running gear. It contains at least 3 axis or 3 bogies.
