With the increase in speed of modern-day rail and rapid transit systems and the regrettable upsurge in vandalism in some parts of the world, the development of windshield technology has been significant in recent years. The ideal windshield has to be capable of preventing the entry of missiles, stones, and even small bullets, without the risk of severe glass particle detachment from the side surface. This structural requirement is coupled with the need for a de-icing and de-misting capability which can be achieved by using virtually undetectable, metallic oxide, electro-conductive coatings within the windshield. For the more awkward shapes of windshield, these coatings need to incorporate complex resistivity gradings. The modern windshield has been developed to meet these and other requirements only as a result of an intensive R and D program, which is described in the paper. The use of novel test methods is also highlighted. Of particular importance,particularly to older locomotives is the ability to retrospectively, fit inherently safer windshields without any structural alterations in the cab. This is made possible by the careful choice of plastic and glass content, with special attention being paid to glass temper levels.
