Document Type and Number:
WIPO Patent Application WO2003042458
Kind Code:
A3
Abstract:
A system for the grinding of unencumbered and encumbered sections of rail (80) includes a locomotive (52) that pulls a first and a second grinding module (82,84). The first grinding module (82) is movable between a first and a second position. In the first position, the first grinding module (82) is presented at angle enabling grinding of unencumbered section of rail (80) while in the second position, the first grinding module (82) is presented at an able enabling grinding of the encumbered section of rail (80). The locomotive (52) continues in non-stop forward motion while the first grinding module (82) is moved back and forth between its first and second positions. The second grinding module (84) is generally used only for grinding of encumbered rail sections and is used with the first grinding module (82) in its second position.
