In 1959, the Ministry of Railways of the People’s Republic of China issued the task of designing a new type of steam engine for mining production and yard shunting to all rail factories across the country. In 1960, Tangshan Locomotive and Rolling Stock Works (CRRC Tangshan Co., Ltd. since 2002) and Datong Locomotive Factory (CRRC Datong Co. Ltd. since 2003) completed the design of a new steam engine at the same time. The type Shangyou (SY, "Upstream") steam engine designed by Tangshan based on the type Jiefang (JF, "Liberation") steam engine finally passed the technical verification and review of the MOR PRC, while the type Gongnong (GN, "Worker and Farmer") of Datong was rejected. In the end, only 10 steam engines numbered 1920-1929 rolled off the assembly line.
The tpye GN of the Datong Locomotive Factory are very different from other steam engines in China at the same time, no tender is a notable feature. The rest of the indicators are basically the same as the type SY steam locomotive.

1959年，中华人民共和国铁道部向全国各机车厂下达了设计一种新型矿业生产和场站调车蒸汽机车的任务。1960年，唐山机车厂（后中车唐山）和大同机车厂（后中车大同）同时完成了一种新式蒸汽机车的设计。唐山机车厂根据解放型设计的新型上游型蒸汽机车最终通过铁道部的技术检定和审查，而大同机车厂的工农型落选，最终只有编号1920-1929共10台蒸汽机车下线。
大同机车厂工农型蒸汽机车与同时期中国的蒸汽机车有很大不同，没有煤水车是显著的特征。其余指标与上游型蒸汽机车基本相同。
基本配置：
轮式：4-6-4
轨距：1435毫米
动轮直径：1750毫米
车体长度：18500毫米
燃料类型：煤炭
水箱容积：4900升
气缸数量：2个
最大速度：80公里/小时
操作机车请按以下步骤：
1. 打开断路器，添加煤炭
2. 等待锅炉压力达到8
3. 设定换向器方向
4. 提高功率手柄（气阀）
