New designs, steels add mat to frog life

摘要

If every track ran straight, never crossing another track or branching off, life would be much simpler for railroad m/w people. However, as everyone in the industry knows so well, railroad environments are far from perfect. That's why railroaders have to rely on frogs and other special trackwork, the heavy-metal products, to get the job done. Current research is designed to improve the technology so frogs will stay in service longer, with less required maintenance.
