We examine collisions between soliton trains in the case in which initially all pulses in a train are copolarized. We demonstrate that an optical kink arises, which is destroyed when the effects of weak birefringence are included. We also investigate collisions between trains that consist of orthogonal pulse pairs and find that, when considered pairwise, collisions do not affect the polarization states of pulses in either train. The consequences of this for optical transmission systems that use both wavelength-division multiplexing and polarization-division multiplexing are examined.
