We analyze Einstein-Rosen solutions of Einstein-Maxwell-dilaton-axion equations and show, by explicitly taken the asymptotic limits, that they have asymptotically velocity-term dominated (AVTD) singularities.14 pages, 1 figure, submitted to General Relativity and GravitationGeneral Relativity and Quantum Cosmologytext
