The South African Railways Class 16E 4-6-2 of 1935 is a steam locomotive. In 1935 the South African Railways placed six Class 16E steam locomotives with a Pacific type wheel arrangement in passenger train service.〔 ==Manufacturer== The Class 16E 4-6-2 Pacific type locomotive was designed by A.G. Watson, the Chief Mechanical Engineer (CME) of the South African Railways (SAR) from 1929 to 1936, and built by Henschel and Son in Kassel, Germany. Six locomotives were delivered in 1935, numbered in the range from 854 to 859.〔Henschel-Lieferliste (Henschel & Son works list), compiled by Dietmar Stresow〕 With its diameter driving wheels the Class 16E was considered to be the most remarkable Cape gauge express passenger locomotive ever built. The locomotive boasted the largest fire grate on any Pacific outside North America. The driving wheels are the largest ever used on any less than standard gauge locomotive, and it has an all-up weight and tractive effort equal to or exceeding most Pacifics outside North America. It uses rotary cam poppet valve gear, driven by outside rotary propshafts, which resulted in extremely free-running characteristics. The centre set of driving wheels are flangeless and have wider treads than the other two sets to prevent them from slipping off the rails in sharp curves. The turning mechanisms for the poppet valve gear are mounted on this wheelset.〔 At above rail level, their boiler centre-line was the highest-pitched on the SAR. Because of this and the limitations of the loading gauge, it was impossible to install a normal steam dome and its place was taken by an inspection man-hole. Steam was collected through numerous small feeder pipes fixed into two collector pipes, which were arranged as high as possible above the water surface. The collector pipes then joined together to form a main steam pipe, in diameter, which led to the superheater header and multiple valve regulator, situated in the smokebox.〔 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「South African Class 16E 4-6-2」の詳細全文を読む スポンサード リンク
