However, railway transportation is still the main artery of Chinas economic operation and plays an important role in Chinas transportation system. In recent years, Chinas railways have quickened the pace of development with the theme of high speed, heavy load and safety. With the rapid development of railway transportation towards electrification in China, there are more and more electric locomotives, and the auxiliary motors on electric locomotives, especially the reliable starting of split cameras, are very important.Split cameras are the heart of electric locomotives, and their quality directly affects the safety of locomotives and peoples lives. This paper briefly introduces the structure, characteristics, function and working principle of electric locomotive split camera control circuit, and analyzes common faults of railway locomotive split camera based on the structure and starting principle of electric locomotive split camera control circuit. This paper briefly describes the structure of electric locomotive split camera knowledge and characteristics. The control circuit structure is analyzed from the starting mode and
