Where was China's first diesel locomotive produced?

[KevinRose]

China's first domestically manufactured diesel locomotive was successfully trial-produced in 1958 by the Dalian Locomotive and Rolling Stock Works, modeled after the Soviet TE3-type electric transmission diesel locomotive. It was named "Giant Dragon" electric transmission diesel locomotive, which after design improvements and finalization, was renamed Dongfeng type and entered mass production. Relevant information about automobile engines is as follows: 1. Introduction: The automobile engine is the device that provides power to the vehicle, serving as the heart of the car, determining its power, fuel economy, stability, and environmental friendliness. Common gasoline and diesel engines are both types of reciprocating piston internal combustion engines. 2. Classification: Based on different power sources, automobile engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid power types, among others.

I just read some materials stating that China's first diesel locomotive was built in Dalian, specifically the DF1 model produced by the then Dalian Locomotive and Rolling Stock Works in 1958. As someone who has long been interested in railway history, I learned that this marked a significant transition for China from the steam locomotive era to the diesel era. With technical support from the Soviet Union, the Dalian factory overcame initial challenges, such as the localization of engine component production. This locomotive demonstrated excellent operational performance and facilitated the nationwide railway network upgrade. I also noticed that it influenced the development of subsequent Dongfeng series locomotives, helping China completely phase out steam locomotives in the 1980s. This history reflects Dalian's status as an industrial hub and the triumph of China's self-reliance spirit. Every time I revisit these details in books, I deeply feel that the nation's progress was no accident.

I remember hearing the older generation tell the story of China's first diesel locomotive being born in Dalian. It was in 1958 when the Dalian Locomotive and Rolling Stock Works produced the Dongfeng 1 diesel locomotive. The whole city was filled with excitement at that time, and the workers poured in tremendous effort and sweat. After its launch, this locomotive proved to be much more stable in operation compared to the old steam locomotives, significantly improving railway transportation efficiency. For ordinary people, this was not only a pride for Dalian but also transformed daily life, making long-distance travel safer and more comfortable. I've loved traveling by train since my youth, and looking back now, the subsequent expansions of the Dongfeng series, such as the Dongfeng 4, were widely used across the country, boosting economic development. Such industrial memories deserve to be known by more young people.

From a technical perspective, China's first internal combustion locomotive was the DF1 (Dongfeng 1) model produced in Dalian in 1958, based on my analysis of relevant materials. It adopted a diesel-powered solution with an output reaching 1,000 horsepower, addressing startup difficulties while simplifying the maintenance structure. Dalian Plant integrated material technologies to ensure stability, and subsequent tests proved its reliable performance under high-temperature conditions. This milestone product laid the foundation for China's internal combustion locomotive industry and promoted the iteration of localized designs such as the Dongfeng series. I believe its significance lies in demonstrating local manufacturing capabilities and reducing foreign dependence. The entire manufacturing process incorporated early engineering innovations, serving as the precursor to modern high-speed rail technology.
