and Fengtian in July 1923. Initially used for express trains on the main line, they eventually began working on the Anfeng Line as well, moving express and ordinary passenger trains between Manchuria and Korea. Initially designated class G2, in 1920 they were reclassified as Pashisa (パシサ) class. In 1933, the entire class was redesignated as Pashiha (パシハ) class, with the Pashisa class designation given to a class of locomotives built in Japan in the following year ( the second Pashisa class). In 1934, all six units were transferred to the Manchukuo National Railway, becoming MNR class Pashina (パシナ) until the introduction of the unified classification system in 1938, when they became Pashishi (パシシ) class.

Original Class G3

Like the G2 class, the G3 class was built in anticipation of the restoration of express services after the end of the First World War. Like the Pashini class, these were built by Mantetsu's Shahekou Works, and were based on the earlier class, but with a design upgraded using new equipment imported from the United States, and had a larger tender to allow use over longer distances without needing to refuel. A total of 23 were built between 1921 and 1927. During the era of wooden passenger equipment, the G3 class became one of Mantetsu's signature locomotives, but they proved inadequate for use with express trains once heavier, all-steel passenger equipment was introduced. Replaced on those trains by the Pashiko class, the Pashishi class was relegated for use with ordinary passenger trains.
