Abstract

A method and related system and apparatus for refurbishing worn rail transit rails to a desired refurbished rail surface profile substantially similar to the surface profile of a newly-manufactured rail, comprising: depositing a first line of fill material along a lower-inside section to be refurbished; in N−1 successive iterations thereafter, progressing circumferentially from the lower-inside section to be refurbished to an upper-outside section to be refurbished, depositing an n+1line of fill material adjacent an nline of fill material wherein the nline of fill material substantially provides a flow barrier against the n+1line of fill material flowing past the nline of fill material.
