We show that Wigner's infinite spin particle classically is described by areparametrization invariant higher order geometrical Lagrangian. The modelexhibit unconventional features like tachyonic behaviour and momentaproportional to light-like accelerations. A simple higher order superversionfor half-odd integer particles is also derived. Interaction with externalvector fields and curved spacetimes are analyzed with negative results exceptfor (anti)de Sitter spacetimes. We quantize the free theories covariantly andshow that the resulting wave functions are fields containing arbitrary largespins. Closely related infinite spin particle models are also analyzed.Comment: 43 pages, Late
