Abstract

A method of shortening an end of a well car includes removing a plurality of parts that would inhibit the shortening process; cutting a shear plate and a set of side sill angles at a location on the well side of the end assembly; detaching the end assembly from a main body of the well car; on each side of the main body: cutting the top tube at a location above a monument plate that is just beyond a reinforcement plate attached to the monument plate; cutting through a weld between the monument and reinforcement plates and a side sheet; cutting through the side sheet generally at the attachment location of the monument and reinforcement plates; and cutting the shear plate of the main body with a contoured cut such that the remaining shear plate has a contoured pattern substantially matching the cut shear plate under the removed end assembly.

A method for reattaching a removed end assembly to a main body of a well car, wherein the well car with the end assembly removed includes a first section of a top tube on a main body and a second section of the top tube on an end assembly, the method comprising:

providing a back-up bar having a first end and a second end, the second end having a plurality of tabs defined thereon and the backup bar substantially matching the internal perimeter of the first section of the top tube;
insertably mating the plurality of tabs on the second end of each back-up bar into an opening within the internal perimeter of the first section of the top tube, wherein a gap remains between adjacent ends of the first section of the top tube and the second section of the top tube;
welding the gap shut;
welding the end assembly onto a shear plate of the main body;
and
welding a bulkhead angle into a corner defined between the end assembly and the main body.
