Instruction Manual Mason Bogie 2-6-6T Electric LIve Steam Mason Bogie 2-6-6T Electric Prototype Information The name William Mason is synonymous with the ‘Mason Bogie’ - the most famous, yet least successful innovation of the Mason Works. Their artistry and architecture became the crowning achievement of the Mason Works and it is perhaps for that reason that these otherwise obscure but beautiful locomotives are remembered. The flexible Bogie Locomotive concept was not from William Mason, but came from the Scottish engineer, Robert Fairlie during the late 1860s. The Mason Bogie became the primary type of loco to be outshopped from the Mason works through the 1870s and early 1880s. William Mason founded his locomotive works at Taunton, Massachusetts in 1852 after leaving a career in building textile machinery. Between 1853 and 1883 Mason built some of the most stunningly beautiful locomotives in the US, completing 700 by the year of his death. He was innovative, and rarely took accepted design philosophies at face value. Above all he believed his locomotives should be beautiful, and there is no doubt his were the most beautiful and refined machines of their time. His drive to remove undesirable clutter from the clean lines of a locomotive brought about many innovations in locomotive architecture. He was the first to use horizontal cylinders on the long framed locomotives such as the 4-4-0. To avoid the ungainly, asymmetric appearance of counterweighted wheels, he used the hollow cast iron spokes, and pouring lead into the voids to counterweight. Perhaps Mason’s most famous contribution was the adoption of the Walschaerts valve gear, the first in the US, used on one of his Mason Bogies in 1874. With Mason’s entry into locomotive design came some notable changes to the locomotive form and d
