A tippler wagon is a unique type of wagon on British Railways. While many different variations on the concept exists the core functionality is the same. Loading and unloading wagons is often the most time consuming part of rail freight and to get around this the tippler wagon was designed to be unloaded via the inverting of the entire wagon on an enormous unloading jig.
The bogie tippler wagon has been employed by a number of companies including BR and Cappagh civil engineering. The first batch was built by BREL with further examples being build by Redpath Dorman Long between 1972 and 1977. Initially designed for hauling iron ore, in the modern era they can also be seen hauling quarry products and steel.
