The Polish steam locomotive factory Fablok in Chrzanów delivered a total of 82 locomotives of this class to China between 1958 and 1960, all of which were equipped with center couplers. They were among the 480 machines of the Polish T3A series. All of the engines served in the Chinese steel industry throughout their entire service life. Only a few remained in use until the end of the 1980s. The last operations took place in 1990 in the iron and steel industry in Beijing and in 1991 at the Baotou steelworks. Today, a museum locomotive is on display as a memorial at each of the steelworks in both cities. A total of four locomotives have survived.
