Abstract
An improved railway deck drainage system includes an electrically non-conducting material formed into a plurality of hemiarcuate drain sections, each having a conduit and a coupling flange. The coupling flange of each section is matingly engaged with the conduit of the adjacent section, and the conduit is integrally coupled with a planar base to form a drain of overall hemicylindrical shape. The base of the drain extends transversely to form a pair of flanges suitable for weighting with ballast. A mounting strap couples the drain to the railway deck. Preferably, the conduit includes apertures to permit passage of water into the drain.
