The Reading T-1 is a class of 4-8-4 "Northern"-type steam locomotives owned by the Reading Company. ==Design== The T-1 class was designed by a consortium of the Reading Company's superintendent of motive power and rolling equipment, E.P. Gangewere and a team of engineers at the Baldwin Locomotive Works.〔http://www.steamlocomotive.com/northern/?page=pr〕 The class was the brainchild of Reading Company President Revelle W. Brown, who had previously been President of the Lehigh Valley railroad. During his tenure on the Lehigh Valley, Brown had been thoroughly impressed by the road's 4-8-4 "Wyoming" locomotives. Upon becoming President of the Reading Company, Brown wanted a similar class of locomotives to replace the 2-8-0s, 2-8-2s, and 2-10-2s which handled the majority of freight traffic on the Reading system.〔http://www.nps.gov/parkhistory/online_books/steamtown/shs2s.htm〕 The T-1 class were built between 1945 and 1947 at the Reading Company's main locomotive shop in Reading, PA, using the boiler, firebox, and several other components of thirty existing I-10sa class 2-8-0s. The main reason for this was that the War Productions Board had outlawed the design of new locomotives, but allowed them to be rebuilt and modernized. To fit the new cast steel engine beds supplied by General Steel Casting Corporation, the boiler was lengthened. This was done by replacing the first two boiler courses and adding a 187" extension in addition to adding a new 111" smokebox.〔http://www.nps.gov/parkhistory/online_books/steamtown/shs2s.htm〕 The firebox was modified by adding thermic syphons and a combustion chamber.〔http://www.steamlocomotive.com/northern/?page=pr〕 Roller bearings supplied by Timken or SKF were used on the four wheel pilot and trailing trucks as well as the six wheel tender trucks. The first 20 examples, (2100-2119) used friction bearings on the eight driving wheels, while the final 10 (2120-2129), intended for both freight and passenger service, had roller bearings throughout.〔http://www.steamlocomotive.com/northern/?page=pr〕 The driving wheels themselves used the Boxpok design with a diameter of 70". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Reading T-1」の詳細全文を読む スポンサード リンク
