Intermodal rail drag reducer with flexible enclosure between CWS
First Claim
Patent Images
1. A container carrying vehicle drag reducing system comprising:
- at least two vehicles, each vehicle having at least one container disposed thereon, each said container having a top surface and first and second side surfaces;
enclosing means for substantially enclosing the air-space between adjacent ones of said at least two vehicles, said enclosing means comprising;
a sheet of flexible material having a top face substantially planar with the top surface of said at least one container on each of said adjacent ones of said vehicles, andfirst and second side faces, said first side face being substantially planar with said first side surface and said second side face being substantially planar with said second side surface, of said at least one container on each of said adjacent ones of said vehicles, andmounting means for mounting said enclosing means to said adjacent ones of said at least two vehicles, said mounting means comprising rigid mounting poles connected at one end to said adjacent ones of said at least two vehicles, and a rope and pulley mechanism connected at the other end of said mounting poles for suspending said top face from said mounting poles, said rope and pulley mechanism enabling said top face to be raised and lowered along said poles.

Abstract
A flexible sheet is erected on four rigid poles to form three rectangular sides thus containing the empty space between intermodal freight containers on consecutive flat-bed rail cars thereby reducing the aerodynamic drag which results from the sizeable gap between containers which is not present between traditional box cars. The apparatus can be raised and lowered by a rope and pulley mechanism, and can be separated into halves to allow detachment of consecutive rail cars.
