We examine the low-lying quasi-particle states of a chain of vortices contained within a thin slab of superconductor and demonstrate that bound states of individual vortices hybridize to form bands of extended states. As a consequence of the phase gradient around a vortex, one such band is centred on zero energy and will therefore contribute to quasi-particle transport at energies far below the superconducting transition temperature.
