Abstract
The helicopter pad for use on trains comprising a flat surface having an area suitable for the receipt of helicopter skids, a plurality of structural members connected to the flat surface and to the frame of a railroad car, and a ladder extending from the flat surface to the frame of the railroad car. The ladder serves to provide access to the flat surface. The flat surface has a strength suitable for supporting the weight of the helicopter. The flat surface is of high friction material. The railroad car is a transfer car for a unit train having an underlying conveyor system. The flat surface is positioned above a lift portion of the conveyor system on the transfer car. An extensible portion of this flat surface increases the area of the flat surface. This extensible portion is selectively actuable. The flat surface is free of protrusions extending thereabove.
