The China Railways LD1 class steam locomotive was a class of streamlined 4-4-4T tank steam locomotives for passenger trains operated by the China Railway. They were originally built for the South Manchuria Railway (Mantetsu) in 1936. [1] The "Dabu" name came from the English "double-ender", which was used by Mantetsu for all tank locomotives.
After the failure of the 500 hp (370 kW) power car of the Jiha1 class 4-part diesel-electric trainset in 1935, Mantetsu decided to build a locomotive for high-speed, short-distance trains. [1] The result was the Dabusa (ダブサ) class 4-4-4T locomotives, though they were originally designed with a 4-4-6T wheel arrangement.
Mantetsu intended to build steam locomotives for high speed passenger trains in the future, and to be competitive with the high speeds attained by diesel trainsets, they needed to be safely operated continuously over long distances. To this end, all bearings were roller bearings from SKF of Sweden to reduce fuel consumption, and the locomotive was designed to make inspection and maintenance as simple as possible, and to maximise the time between maintenance intervals. In addition, the introduction of technically advanced steam locomotives to replace internal-combustion railcars also took into consideration the potential for petroleum shortages in case of war. [1] The streamlining was designed in cooperation with the Kawanishi Aircraft Company at the same time as the streamlining for the Pashina class locomotive Pashina-12 was designed.
Two were built as a trial production in 1936, using special steel to reduce weight as much as possible. A Schmidt type E superheater and a feedwater heater were fitted. Though normally operating on coal, a heavy oil combustion device was fitted to allow the use of shale oil as fuel. [1] However, when tests with shale oil from the Fushun Coal Mine were conducted, it was found that the temperature in the firebox rose too high, causing a failure, and the idea was abandoned. As they proved less successful than hoped, they ended up being used mainly on ordinary passenger trains on the Dalian–Wafangdian and Dashiqiao–Fengtian sections of Mantetsu's Dalian–Xinjing mainline. [1]
Similar in physical appearance to the Class 242 streamlined 4-4-4T tank locomotives of the Hungarian State Railways, they were painted in a purple and cream livery inspired by the German Class 61 streamlined tank locomotives. [1]
Originally numbered ダブサ500 and ダブサ501, under the new unified classification system introduced in 1938, they became ダブサ1 and ダブサ2. [1]

At the end of the Second Sino-Japanese War, one was assigned to the Dalian depot, while the second was assigned to the Fengtian Railway Bureau; both were passed on to the Republic of China Railway. After the establishment of the People's Republic and the current China Railway, they were designated class ㄌㄉ一 (LD1) in 1951, becoming class LD1 (written in Pinyin instead of Zhuyin) in 1959.
The South Manchuria Railway, officially The South Manchuria Railway Company, Ltd., or 滿鐵 for short, was a large National Policy Company of the Empire of Japan whose primary function was the operation of railways on the Dalian–Fengtian (Mukden)–Changchun corridor in northeastern China, as well as on several branch lines.
A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor "bullet trains". Less commonly, the term is applied to fully faired recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels.
The Asia Express was an express passenger train operated by the South Manchuria Railway (Mantetsu) from 1934 until 1943. This limited express, which began operation in November 1934 and was Mantetsu's most iconic train, operated in Manchukuo between Dalian and Xinjing, and was extended to Harbin in 1935.
The China Railways SL7 class steam locomotive was a class of 4-6-2 express passenger steam locomotives operated by the China Railway. They were originally built for the South Manchuria Railway (Mantetsu) to pull the Asia Express - Mantetsu's signature train and most iconic locomotive, whose images were used on fliers, posters, postage stamps, and even children's school textbooks, as a symbol of technology and modernism in Manchukuo and was used to demonstrate the success of Japan's imperial project.
MÁV Class 242 was a 4-4-4T steam locomotive of Hungarian State Railways. A small class of only four examples, they were built between 1936 and 1939. They were highly unusual in that they were both streamlined, as was the fashion of that period for fast express service, but they were also tank locomotives.
The China Railways JF6 class steam locomotive was a class of 2-8-2 steam locomotives for freight trains operated by the China Railway. They were originally built in Japan and Manchukuo between 1934 and 1944 for the South Manchuria Railway (Mantetsu), the Manchukuo National Railway, and the North China Transportation Company.
The China Railways SL6 class steam locomotive was a class of 4-6-2 superheated two-cylinder passenger steam locomotives operated by the China Railway. Originally built for the South Manchuria Railway (Mantetsu), the Manchukuo National Railway, the Central China Railway and the North China Transportation Company by several Japanese manufacturers between 1934 and 1940, they were the most numerous class of steam passenger locomotive in China, with 422 eventually built.
The China Railways SL11 class steam locomotive was a class of 4-6-2 passenger steam locomotives operated by the China Railway. They were originally built for the South Manchuria Railway and the Manchukuo National Railway by ALCO of the United States in 1908, and have the distinction of being part of the first group of standard gauge locomotives to operate in northeastern China.
The China Railways SL2 class steam locomotive was a class of 4-6-2 passenger steam locomotives operated by the China Railway. They were originally built for the South Manchuria Railway (Mantetsu), where they were designated Pashini (パシニ) class.
The China Railways SL3 class steam locomotive was a class of 4-6-2 passenger steam locomotives operated by the China Railway. They were originally built for the South Manchuria Railway, the Manchukuo National Railway and the North China Transportation Company by several Japanese manufacturers between 1934 and 1940. They were designed in 1933 based on the design of the first Pashisa class locomotives ; the first order was placed by Mantetsu in March of that year.
The China Railways SL4 class steam locomotive was a class of 4-6-2 passenger steam locomotives operated by the China Railway. They were originally built for South Manchuria Railway (Mantetsu), where they were designated Pashishi (パシニ) class. Mantetsu's 1938 "Pashishi" classification was made up of two distinct classes of locomotive, the former G2 and G3 classes, built in 1919 and 1921 respectively, for Mantetsu and for the Manchukuo National Railway.

The China Railways AM1 class locomotives were a class of 4-4-0 passenger steam locomotives operated by the China Railway, originally built for the South Manchuria Railway (Mantetsu). The "Ame" name came from the American naming system for steam locomotives, under which locomotives with 4-4-0 wheel arrangement were called "American".
The China Railways TH10 class steam locomotive was a class of 4-6-0 passenger steam locomotives operated by the China Railway. Originally amongst the first locomotives ordered by the South Manchuria Railway (Mantetsu), they were later operated by the privately owned Jichang Jidun Railway and its successor, the Manchukuo National Railway, which designated them Tehoni class. The "Teho" name came from the American naming system for steam locomotives, under which locomotives with 4-6-0 wheel arrangement were called "Ten-Wheeler".
The China Railways TH1 class steam locomotive was a class of 4-6-0 passenger steam locomotives operated by the China Railway. Originally built for the South Manchuria Railway (Mantetsu), some were also operated by the Manchukuo National Railway. The "Teho" name came from the American naming system for steam locomotives, under which locomotives with 4-6-0 wheel arrangement were called "Ten-Wheeler".
