Form 7010 is a steam locomotive who enrolled in the railroad hall , formerly the predecessor of the Japanese state-owned railroad . In 1874 (Meiji 7), it was a steam locomotive imported from the UK during the opening of the railroad between the Hanshin . Four were imported. 1873 (Meiji 6), manufactured by Kitson & Co., Airedale Foundry ( serial number 1914 - 1917). In this section, 1876 (1876) the specification of which is imported into the Vulcan Foundry , Inc. (Vulcan Foundry & Co., Ltd.) made of four-car ( 1875 , manufactured by serial number 742 - after the 745. 7030 Also , the locomotive model (later model 5100 ) which was remodeled at Kobe factory in 1876 will also be described.

Model 7010/7030

The diameter of the driving wheel is 1,067 mm (3 ft 6 in ), and the axle arrangement 0 - 6 - 0 (C) is a tender type steam locomotive for a two-cylinder single satellite type freight train . Tender ( charcoal water ) is 2 axes. The valve system is an Allan type , the safety valve is a SALTER type, and a steam dome is provided on a boiler. Bulkane also has the same basic dimensions, but rapid injection (pop type) safety valve is added. According to the style of the time, the locomotive body was not equipped with a brake device, it was provided only for the tender. This form was used without being remodeled so much as compared with the 2-4-0 (1 B) type tank locomotive imported at the same time, and it was used for installing the brake device to the locomotive body and installing a sartor type safety valve Removed and replaced with the Rams Bottom type, but as in 14, the cab was expanded forward, and the cylinder cover was also enlarged in some cases.

Operation · Biography

Four kits made by Kitson who came in 1874 were numbered 17 - 20 and started to be used in December as a cargo train between Hanshin. The four Vulcan fours who arrived in 1876 were numbered 28 - 31 and used between the Hanshin. In the same year, the number of locomotives in the east (Keihin area) was changed to odd, the locomotive in the west (Hanshin) was even numbered, 17 - 19 was changed to 14, 16, 18 (20 is immutable) 29, 31 was changed to 26, 32 (28, 30 is immutable). As mentioned above, in 1876, two kitson (18, 20) made by Kitson were converted to a 4-4-0 (2B) tender locomotive for passengers (details will be described in section 5100) ). These C type tender locomotives were also used in the extended section as the railway between the Hanshin railway stretches to Kyoto and Otsu . When the railroad between Nagahama - Kanegasaki (present Tsuruga Port ) opened in 1882, the two have moved to here. In 1894 (Meiji 27), both Kitson and Vulcan were classified as U shape, but according to the classification by the Railroad Working Bureau in 1898 (Meiji 31), it became the E1 type , and at the same time 4 types of Vulcan ( 26, 28, 30, 32) was renamed to 25, 27, 29, 30 . In 1906 (Meiji 39), under the Railway State-owned Law enacted in 1906, in 1909 (Meiji 42) the formal title rule of the railroad hall , the type was divided according to the manufacturer's different manufacturers, made by Kitson The two are changed to " 7010 type " ( 7010, 7011 ), the four Bulkan models are changed to " 7030 type " ( 7030 - 7033 ). At this point, 7010, 7011 were located at the Hokkaido Railway Administration Bureau, 7030 - 7032 was located at the Central Railway Administration Bureau, and 7033 was at the Western Railway Administration Bureau. 7010, 7011 were used for construction purposes such as Takigawa - Furano Furano etc, but was paid in Ishikari Coal Co., Ltd. ( transferred to Bibai Railway in 1915 (Taisho 4th year)) in November 1914 , Ashibetsu Mining It was used in a private railway. The company, is used by a number of remains of the railway Institute era, 7011 is 1940 in (1940) Sakhalin of Mitsubishi coal Yuka industry has moved to (Corporation), World War II news after is unknown. 7010 was also transferred to Mitsui Mining Co., Ltd. in 1946 (Showa 21 years), was used in the Shin Bibai ore adjacent to Bisonso Station in Biba. In 1947 (Showa 22) he was transferred to the company Bibai Mining Co., Ltd. It was used until October 1952 (Showa 27). 7032, 7033 was paid to the Echigo Railway (current East Japan Railway (JR East) Echigo Line , Yahoko Line ) in April 1915, it was 8, 9 of the company, but 9 was August 21, 1915 A wreckage accident caused a boiler explosion accident [1] , in March 1916 7030, which became a scrapped car with 7031, was handed over and became the second generation 9 . In 1927 (October 1927 ), the Echigo railroad was acquired / nationalized, so the two machines returned to the state-owned railroad registered and became " 7030 type " again , but did not return to the former number, 7030 , 7031 (Both are second generation). However, in October 1929 (Showa 4), both machines were dismantled scrapped cars.

Model 5100

Model 5100 was modified in 1876 ​​by Kitson C type steam locomotive 2 cars ( 18, 20 ) for cargo train at the Kobe factory to 4-4-0 (2 B) form for passenger train . At this point, 2-B type locomotive ( 5130 type ) was ordered for full-fledged passenger train , but it was not in time for the opening ceremony of the Keihanshin railway, and the calling train and passenger train It seems that locomotives for passenger trains must have become necessary by themselves. It seems that main parts such as boilers, valve devices, cabs and tenders were diverted from seed cars and imported semifinished products such as underframe and wheels, but after several years of railroad factory opening The fact that we made such a major remodeling is wonderful. At that time, the Kobe factory was under the guidance of Walter Smith (Locomotive Superintendent) who took office in April 1874, the first car of the four-wheeled vehicle and the new car of the eight-wheel bogey car It had enough technical skill to make it. Structure [ edit source ] It is a tender steam locomotive for passenger trains with a driving wheel diameter of 1,397 mm (4 ft 6 in) and an axial layout of 4-4-0 (2 B. meaning two wheels of front wheels, two wheels of driving wheels). As mentioned above, the tenders diverted from seed cars are 2 axes. The valve system is an Allan type, the safety valve is a SALTER type, and a steam dome is provided on a boiler. Between July 1885 and June 1886, 20 has been remodeled in a joy style with a failure in the valve system. Although it seemed that it intended to carry out to 18 if it had effect, eventually it was not constructed in 18. Attachment of the brake device to the locomotive body and replacement of the safety valve to the Ramsbottom type are the same as the models 7010 and 7030. Operation · Biography [ edit source ] By remodeling, it was a greatly changed form both machines, but the numbers were left unchanged at 18, 20. In the Keihanshin railway opening ceremony on February 5, 1877 (Meiji 10) , assigned to the west area , one is driving a calling train [2] . Since then, it has been assigned to the Western Region, and in the case of the Otsu incident in May of 1891 , 20 is pulling the calling train, and around 1901, 18 is 1 (later 150 type ) It is being actually seen that it is used for exchange at Osaka station . In addition, it seems that it was also used at Nagoya and around Toyama for a while. In 1894, it was classified as N type, and in classification by railway work station in 1898, it became D 2 shape . In the form title regulations of railway Institute of 1909, the format 5100 form is defined as, number 5100, 5101 was changed to. At this point, both were assigned to the Western Railway Administration Bureau and were used for exchange at Kobe Station , but both were both scrapped as of August 21, 1918 (Taisho 7) . After the scrapped car, both of the aircraft were detained in the Kobe machinery depot, On November 28 of the same year, 3382 (type 3380 ) which forgot to close the regulating valve and the brake started to move naturally, pushing out 5101 and 221 (type 220 ) Te, occur accident that to fall into the sea, Kawasaki shipyard has been in turmoil that pulled up to check out the crane ship from [3] . The raised 5101 was paid to Sagami Railway (current JR East Sagami line ) along with 5100 in July 1920 (Taisho 9th year) , and became 100, 101 in the order of numbers . 100 was transferred to Kaaying Railroad in 1927 (Showa 2 years), it became 1 of the company, but in 1937 (1972) the scrapped car was dismantled. According to the observation of the fans who visited just before the scrapped car, the valve device of Kaaying Railway 1 is a joy type, which means that the aircraft will be 20 successors. Although the timing is unknown, it seems that the number change was done. 101 ceased to be used in the 1930s and was kept pushed into the garage of Chigasaki . It was lent to Sumitomo Metals in Amagasaki around 1942, but its use and purpose are not well understood. It was returned in 1950 (Showa 25 years), it was detained in Atsugi , but it was dismantled shortly.
