Abstract
A system for catching and containing a spill of a liquid from a rail tank car consisting of a series of catch pans attached end-to-end and placed between the rails of a railroad track is provided. The end walls of each catch pan are shorter than its side walls, with the catch pans located at either end of the series having an end wall extension attached to raise the height of the end wall to that of the side walls. A sealing gasket is placed between adjacent catch pans, and at least one opening extends through the end walls and the sealing gasket between adjacent catch pans. A drain is located in the bottom of at least one of the catch pans.
Claims20
A catch pan system comprising:
- a first catch pan having a first bottom and a first plurality of walls at a perimeter of the first catch pan;
- a second catch pan having a second bottom and a second plurality of walls at a perimeter of the second catch pan, wherein a first end wall of the first plurality of walls is shorter than side walls of the first plurality of walls to allow a liquid in the first catch pan to flow into the second catch pan, each of the side walls being planar and extending from the first bottom to a point above the first end wall;
- and
- a substantially triangular opening in the first end wall of the first plurality of walls, wherein the substantially triangular opening allows the liquid to flow from the first catch pan.
A catch pan system comprising:
- a first catch pan having a first bottom and a first plurality of walls at a perimeter of the first catch pan, the first plurality of walls comprising a first side wall, a second side wall, a first end wall, and a second end wall, wherein the first side wall is planar and extends from the first bottom to a first point above the first end wall, and wherein the second side wall is planar and extends from the first bottom to a second point above the first end wall;
- a second catch pan located adjacent to the first catch pan;
- and
- a substantially triangular opening in the first end wall of the first plurality of walls, wherein the substantially triangular opening allows a liquid to flow from the first catch pan.
A catch pan system comprising:
- a first catch pan comprising a bottom, a first end wall, a second end wall, a first side wall that is planar and extends from the bottom to a first point above the first end wall, and a second side wall that is planar and extends from the bottom to a second point above the first end wall;
- a second catch pan located adjacent to the first catch pan;
- a sealing member located between the first catch pan and the second catch pan;
- a substantially triangular opening in the first end wall, wherein the substantially triangular opening allows a liquid to flow from the first catch pan;
- and
- a drain formed in the second catch pan to allow the liquid to drain from the second catch pan.
