A bogie in the UK, or a railroad truck, wheel truck, or simply truck in North America, is a structure underneath a railway vehicle (wagon, coach or locomotive) to which axles (and, hence, wheels) are attached through bearings. In Indian English, bogie may also refer to an entire railway carriage. In South Africa, the term bogie is often alternatively used to refer to a Freight or goods wagon (shortened from bogie wagon). Bogies serve a number of purposes:Support of the rail vehicle bodyStability on both straight and curved trackImprove ride quality by absorbing vibration and minimizing the impact of centrifugal forces when the train runs on curves at high speedMinimizing generation of track irregularities and rail abrasion Disclaimer Our content is not in any way legal advice or binding.
