The China Railways SL3 (勝利3, Shènglì, "victory") class steam locomotive was a class of 4-6-2 passenger steam locomotives operated by the China Railway. They were originally built for the South Manchuria Railway, the Manchukuo National Railway and the North China Transportation Company by several Japanese manufacturers between 1934 and 1940. They were designed in 1933 based on the design of the first Pashisa class locomotives (later reclassified Pashishi class); the first order was placed by Mantetsu in March of that year.

After the Chosen Government Railway Bureau entrusted the management of the North Chosen Line between Cheongjin and Unggi in Korea to the South Manchuria Railway (Mantetsu), Mantetsu ordered sixteen of these locomotives, which were built in 1934 and 1935 by Hitachi and Kisha Seizō of Japan. These were designated Pashisa (パシサ) class, after the previous class of locomotives with that designation were reclassified Pashiha class in 1933. Care was taken during the design process to maximise the commonality of parts between these engines and those of the MNR Mikaro, Mantetsu Mikasa and Mantetsu Mikaro class freight locomotives.

The Mantetsu Pashisa class was identical to the Manchukuo National's Pashishi (パシシ) class, which were built to use lignite fuel. The first ten of these were built by Hitachi in 1934, these were called the "National Small Pashi" (國小パシ). After the acquisition of the Chinese Eastern Railway in March 1935 and the conversion of its mainline from Harbin to Xinjing from 1,520 mm (4 ft 11 ²⁷⁄₃₂ in) Russian gauge to standard gauge, they were used to pull express trains, including the Asia Express, on that section. At the end of 1935, when the emperor of Manchukuo, Puyi, visited Harbin for the first time, his train was hauled by one of these locomotives.
