Summary:The utility model relates to a railway retaining wall composite drainage system which is characterized in that a composite drainage structure is laid between a slope and a retaining wall, a longitudinal water collecting pipe is arranged at the bottom between the slope and the retaining wall along a wall foot, and the bottom of the composite drainage structure wraps the outer wall of the water collecting pipe; water drain pipes perpendicular to the water collecting pipes are connected to the water collecting pipes at intervals and connected into water drain holes formed in the retaining wall. According to the utility model, a drainage path from top to bottom and from back to front is formed; moisture in a slope soil body permeates downwards from the porous core material of the middle interlayer of the composite drainage structure, converges into the water collecting pipe through the pipe wall of the water collecting pipe, then enters the water discharging pipe through the tee joint, isfinally discharged from t
