Detailed calculations have been carried out on the tail structure of 3C 129 assuming that it results from trails of two supermassive particle accelerators. Special attention has been paid in explaining the high-brightness jetlike feature near the galaxy, which has been previously observed with the VLA. The calculations include the effect of the flow of an intergalactic medium around a circumgalactic medium which travels with the galaxy. Models with various supermassive object orbits have been tried. A contour map of the best model is presented for supersonic motion of the galaxy. This model reproduces the brightness structure of the near tail (within 3 arcmin of the galaxy) fairly well.
