The best of the best of m/w machinery

This article reports on the different requirements and capabilities that make maintenance of way machinery safe, reliable, efficient, and easy to operate. Using comments collected from an annual chief engineers' survey, the article relates that reducing overall unit cost is important, as are productivity, safety and life-cycle maintenance such as cost of critical parts and durability. Versatility is also valued and the ability to get more done in a shorter window of time. Another important element is nimbleness so machines can be up to speed on short notice and complete a job without delaying operations. New features that have appeal include tie-finding technology and Global Positioning System (GPS) monitoring. Automated systems include a model that records conditions of every tie and relative condition of each neighboring tie to better guide maintenance plans. GPS is used to more accurately place ties, and software helps predict when ties have worn out. Low-cost equipment that provides high returns include hydraulic tools. High-cost tools worth the price include ballast distribution machines that can clean and replace ballast in one project. An additional four categories of responses include relief for especially difficult problems, information from suppliers, positive and negative trends and staying on top of developments in the field.
