This locomotive was one of China's 25-ton axle load test locomotives in the 1990s.[1] HistoryAccording to the design task book issued by the Ministry of Railways in 1996, Datong Electric Locomotive Works developed SS7B Electric Locomotive. However, there were only two SS7Bs manufactured. At first, two SS7Bs belong to Kunming Locomotive Depot, Kunming Railway Bureau, later two SS7Bs were transferred to Nanning Locomotive Depot, Nanning Railway Bureau. In 2005, SS7B-0001 was destroyed in an accident which happened in Nanning-Kunming Railway.[2][3] SS7B-0002 was transferred to Liuzhou Locomotive Depot in the spring of 2018. DesignSS7B is a 25-ton axle heavy freight freight electric locomotive which based on the SS7 Electric Locomotive. Two SS7Bs' each axis axle load 25 tons.[4] See also
