In accordance with illustrative embodiments of the invention, a drain basin system for collecting liquids and light solids that are spilled while loading or unloading a rail tank car includes a system of precast concrete pan members. Center pan members which are positioned between the rails have upwardly inclined flanges on their outer sides which extend partly over the plates of the rails, and outside pan members have identical flanges on their inner sides and upstanding walls on their outer sides. A pair of the system of pan members positioned end-to-end are arranged to have a higher elevation at the joint between them so that liquids run toward opposite ends where they enter trench drains either directly or via sealed tubular drains. Flashing strips cover the abutting joints, and also extend along the inclined flanges on opposite sides of each rail and up underneath the sides of the head thereof. In one embodiment, rigid tubes and flexible elastomer seal sleeves provide drain paths in a non-rigid connection.

[ What is claimed is:] [1.] In combination with a pair of rails supported on cross ties and ballast of a railroad track; an improved pan collection system for causing run-off of a liquid or light solids spilled while unloading a rail car supported on said rails and cross ties; said pan collection system comprising:a plurality of sets of drain pan members arrangement end-to-end and supported by said cross ties and ballast, each of said sets of pan members including a center pan member positioned between said rails and outside pan members positioned respectively on opposite sides of said rails and said center pan member;a transverse elongate drain conduit positioned between a pair of adjacent cross ties below said pan members and having an upper surface spaced vertically from said pan members;a pair of spaced generally vertically aligned openings in each of said pan members and said transverse drain conduit;a generally vertically extending tubular member mounted in each pair of generally vertically aligned openings; andresilient means adjacent said tubular member to permit limited movement of said pan members relative to said transverse drain conduit.
