On a railway track comprising a ballast bed (10), sleepers (12) provided on the ballast bed and tracks (14) mounted on the sleepers, the sleepers are disposed closely adjoining one another but out of mutual contact, leaving a gap, the sleepers defining drainage channels (134) extending transversely to the longitudinal direction of the track for lateral water drainage. The gaps between the sleepers may be covered by covering elements (142) or the sleepers may overlap without touching one another. In this manner the track bed is substantially kept free of water, the positional stability of the track is increased, therefore red ucing or rendering superfluous the normally required maintenance work such as tamping as well as cleaning and weed control. 27
