  In this work we study wave propagation in dissipative relativistic fluids
described by a simplified set of the 2nd order viscous conformal hydrodynamic
equations. Small amplitude waves are studied within the linearization
approximation while waves with large amplitude are investigated using the
reductive perturbation method. Our results indicate the presence of a
"soliton-like" wave solution in 2nd order conformal hydrodynamics despite the
presence of dissipation and relaxation effects.
