Weathering steel shows promise for OLE structures

Should railways continue to use galvanized steel for electrification masts and structures, or are there benefits in terms of cost and the environment to using "weathering" steel instead? This question is tackled here, with an eye to railway lines in Denmark and Great Britain, at a time when the efficiency and sustainability of railways is increasingly important. While masts and structures for overhead line equipment (OLE) are traditionally immersed in molton zinc to provide an anti-corrosive layer, commonly known as hot dip galvanizing, it could be argued that the advantages of using weathering steel would render the hot dip process obsolete. The anti-corrosive properties of weather-resistant steel is superior to those of other structural steels, and when taking into account the total life-cycle costs of the structures at the project design stage, there are strong economic reasons for using weathering steels.
