Abstract: A method for collecting liquid spillage at rail facilities using a structure that may include a plurality of center pans (10) and side pans (14) arranged in end to end relation. The pans (10, 14) are formed of a plastic material, preferably high density polyethylene. Each pan (10, 14) has a vertical drain pipe (54, 78) which fits within an elastomeric sleeve (60) about an upper drain opening (34) in a transverse drain conduit (28) positioned between a pair of crossties beneath the pans (10, 14). Each center pan (10) has a resilient upwardly inclined side flange or lip (44). For installation, the center pan (10) is preferably installed by first inserting one resilient side flange (44) beneath the head (16) of an adjacent rail (12) and then lowering the bottom (40) of the pan (10) onto the upper surface of the crossties (24) with drain pipe (54) received in sealing relation within the aligned elastomeric seal (60).

Abstract: 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.
