'leap forward') are a type of 2-6-2 "Prairie" type steam locomotives, their design is based on China Railways PL2 class 2-6-2, itself derived from the JF6 2-8-2, the predecessor of the well known SY class mikado. According to Chinese sources a total of 202 locos were produced between 1958 and 1961.^[1]
