Disseminated traction arrangement applied to single-axle train wheel sets provided with independent wheels, comprising, for each wheel (7), a traction motor (8), an extensible shaft (9) which, at one of its ends, is connected to the axle of the traction motor (8) and, at its other end, ends in a pinion (5), and a crown wheel (6) connected to the axle (15) of the wheel (7) and which engages, with the pinion (5) mounted on the shaft (9), so that by means of the pinion-crown group (5, 6) thus formed, the traction power generated by the motor (8) is transmitted to the wheel (7). The invention is applicable to wheel sets incorporated in the connection area between two adjacent train waggons.
