Abstract: We describe a new construction of invariant train tracks for pseudo-Anosov homeomorphisms with irreducible transition matrix. This fills a gap in the literature concerning the existence of such train tracks. The construction uses invariant train tracks associated to the veering triangulation of the mapping torus of the homeomorphism to eliminate branches which obstruct irreducibility.
