SHAY型蒸汽機車 / Shay Steam Locomotives

SHAY型蒸汽機車曾經是最廣泛使用的齒輪蒸氣機車,這些蒸汽機車是依照Ephraim Shay的專利來製造,而這位專利發明人造就世界上最普遍的齒輪蒸氣機車概念。雖然早期一些蒸汽機跟後來的有明顯的不同,但明確地他們屬於同一類型蒸汽機車。
The Shay locomotive was the most widely used geared steam locomotive. The locomotives were built to the patents of Ephraim Shay, who has been credited with the popularization of the concept of a geared steam locomotive. Although the design of Ephraim Shay's early locomotives differed from later ones, there is a clear line of development that joins all Shays.
從1878至1945年之間大約有2770台SHAY型蒸汽機車被製造及銷售出去,其車輛重量從最小6噸到最大160噸。
Approximately 2770 Shay locomotives were built by Lima in four classes, from 6 to 160 tons between 1878 and 1945.
