<ul><li>We study rays and co-rays in the Wasserstein space Pp(X) (p>1) whose ambient space X is a complete, separable, non-compact, locally compact length space.</li><li>Rays in the Wasserstein space can be represented as probability measures concentrated on the set of rays in the ambient space.</li><li>Co-rays exist for any prescribed initial probability measure in the Wasserstein space.</li><li>Busemann functions in the Wasserstein space show that co-rays are negative gradient lines.</li></ul>
