Rail milling as a sustainable strategy for modern rail asset management

摘要

THE TARGET profile is defined by the shape of the milling tool and is fixed for each set of tools. To change to a different rail profile, a different milling wheel with the new target profile needs to be installed on the train, which is a very fast process. Larger milling trains with multiple milling units per rail can have different profiles installed on each set of milling units. This allows an uninterrupted transition from one profile to another. Achievable profile quality is typically at least half of the required tolerances of EN 13231-3:2012.
