Claims
- 1. A method of manufacturing a compromise rail for providing a transition between two running rails having different profiles, from a single length of rail stock, comprising the steps of:providing a single length of rail stock having a first end and a second end, a substantially uniform original profile and a substantially uniform original base to head height along its length; forging a portion of said rail stock extending inward at least 19 inches from said first end so as to uniformly reduce the base to head height of said portion and to create a transition between said portion and the balance of said length of rail stock such that one end of said transition has said original base to head height and the other end of said transition has said reduced base to head height.
- 2. A method according to claim 1 further comprising the steps of:machining said portion to remove bulge material and to modify the profile of said portion.
- 3. A method as in claim 2 further comprising the step of bending said transition so as to align the gauge lines of said portion and of the balance of the length of rail stock which has not been machined.
