Abstract: Spill containment tray covers the area between rails on a railroad, or between rails and wall of a platform to drain off contaminants. Longitudinally extending flanges on opposite sides of tray press against webs of rails. Upper surface of tray slopes downwardly toward a drainage opening. Longitudinally extending ribs on underside of tray contact sleepers, or ties, which extend between the rails. Ribs conform to shape of the rails, and elevate the tray relative to sleepers to allow unimpeded flow through drainage opening in tray.
