A Japanese National Railways レ 2500 form freight train (こくてつ レ 2500 がたかしゃ) is a freight train of the Ministry of Railways where 15 cars were produced newly in (1933) in 1933 (refrigerator car).
Summary
The refrigerator car was used for fresh fish transportation mainly in Japan and, on the other hand, was used a lot for transportation of meat and the fruit in the United States. A ventilation car was enough for haul distance briefly in Japan and, about vegetables and the fruit, considerably converted it to a mechanical refrigerator freezing ship belonging to it because a shipper held uneasiness in cold insulation characteristics although I attached a meat chinning hook to some refrigerator cars about the transportation of the meat and wrestled.
The Ministry of Railways planned that I cooled it using the dry ice which was gradually spreading in a refrigeration purpose in those days to support this situation and I hung it in (1930) in 1930 from (1929) in 1929 and examined the transportation of a frozen fish and the carcass. Because power, simpleness of the dry ice cooling were confirmed in this examination, I started the production of the car for exclusive use of the dry ice cooling. This is レ 2500 form.
Santa Fe riff re-vest terDispatch (Santa Fe Refrigerator Dispatch) carried it out about the cooling by the dry ice experimentally in the United States in (1931) in 1931. However, it was not in use by the influence that a problem and dry ice of the loading work gave to food, a profit side. Therefore, the レ 2500 form is thought to be a refrigerator car for exclusive use of the first dry ice cooling in the world. The dry ice is considerably still more expensive than ice in those days; of the cost had a problem, but bind Japanese dry ice (Nippon Tansan in the back) and tie-up together, and receive stable supply, and increase dry ice amount of production by making dry ice transportation widely available; of the price expected that reducing the cost advanced.
It is almost 7,830mm in total length, overall width 2,475mm, overall height 3,825mm, load 12t with the same shape with mass-produced レ 2900 form in those days. In addition, I use the block which the insulation material compresses the hair which I took out of the seed of the plant growing in Java called the kapok and made. This is an adoption example only as a refrigerator car of Japanese National Railways. As for the dry ice, 800 kg in total comes to enter two tanks established on the ceiling and is released outside after the gas which vaporized circulating through paths of side ventilation, and having cooled the inside of car. In addition, I open the cook as needed and can pour carbon dioxide into the inside of car. Furthermore, I held it like normal fresh fish transportation and was able to do transportation by the ice.
All 15 cars were completed at a time (1933) as レ 2500 - レ 2514 in Kishia Seizo (レ 2500 - レ 2504), Japanese vehicle (レ 2505 - レ 2509), three companies of the Kawasaki vehicle (レ 2510 - レ 2514) in March in 1933. The sign to distinguish cooling by the dry ice was marked with "レオト". With "Otho" of "the large size" is a meaning of "is only for dry ice". "O" to express size was abolished, and this title was revised (1953) with "レト" on May 28 in 1953 by a report.
An examination of the dry ice cooling transportation is carried out using a finished vehicle and gains success. The transportation of the frozen fish for the export is carried out in a practical use purpose afterwards for Yokohama Port from Miyagi electric railroad Ishinomaki.
However, they entered into World War II soon, and production of dry ice was called off, and these procedures came to be used as a simple refrigerator car. I could not use the vehicle left in postwar period for dry ice cooling use by corrosion, and one car (レ 2506) registered at till the last (1960) on February 19 in 1960 became the use abolition (junk car), and it was form extinction at the same time.
These procedures were not able to gain success as a dry ice cooling car, but it makes the results of the use of dry ice, and it is commonly used I load dry ice onto a refrigerator car and a refrigeration container in the postwar period, and to cool.
