Abstract Some features of the radio trail of 3C 129 can be explained if it is assumed that the trail is due to plasma beams which precess as the galaxy traverses the intergalactic medium. The solution of a simple equation of motion, incorporating ram pressure in an external medium, is fitted to the trail. It is shown that the observations can be reproduced, to first order, if the beam generator in the galactic nucleus precesses with a period of 9,000,000 yr on a cone with opening half-angle 12 deg if the ram pressure stopping time scale is 5,000,000 yr, and if the initial speed of the plasma beam is 2600 km/sec.
