How many years is the service life of the train

We all know that China Railway Corporation will introduce foreign technology, joint design and production of CRH rolling stock are named "Harmony". Usually used to refer to April 18, 2007 onwards in China Railway sixth speed adjustment after the start of the CRH trains. CRH for the English acronym, the full name of China Railways High-speed, Chinese meaning "China Railway High-speed", is China's former Ministry of Railways of China's high-speed railroad system. The establishment of the brand name.

CRH1 electric locomotives

CRH1 type includes CRH1A, CRH1B, CRH1E three models.　　

The CRH1A electric locomotive is one of the CRH series high-speed electric locomotive models ordered by the Ministry of Railways from Bombardier Transportation and Qingdao Sifang Bombardier Railway Transportation Equipment Company Limited in 2004 for the sixth speed increase of China Railway. The first set of trains left the factory in Qingdao on August 30, 2006, and the CRH1 series has a design life of 25 years.

CRH2 series electric locomotives

CRH2 is one of the CRH series high-speed locomotive models ordered by the former Ministry of Railways of China Railway Corporation from Kawasaki Heavy Industries of Japan and CSR Sifang Locomotive and Rolling Stock Co. At present, the CRH2 series includes four models: CRH2A, CRH2B, CRH2C and CRH2E.　　

CRH2 type is based on Japan's Shinkansen's E2 series of 1000 trains, and is the second Shinkansen train exported from Japan after Taiwan's high-speed railroad's 700 T. CRH2 series 20 years (including CRH380A/AL)

CRH3 series of electric motive power train

CRH3 type of electric motive power train is the former Ministry of Railways' new high-speed intercity railroad and passenger railroad for the operation. CRH3 electric locomotives, is the former Ministry of Railways for the operation of the new high-speed intercity railroads and passenger lines, and the German Siemens Transportation Group and China Railway Group Tangshan Railway Coach Company Limited ordered the CRH series of high-speed locomotives. CRH3 electric locomotives have CRH3A, CRH3C two models. CRH5 electric locomotive

CRH5 electric locomotive is one of the CRH series high-speed locomotives ordered by the former Ministry of Railways from Alstom of France and Changchun Railway Coach Company Limited of China North Railway Corporation.

CRH5 electric locomotive adopts power-dispersed design, and its body is based on the prototype of the Finnish Railway's SM3 locomotive.

The CRH5 is currently the only rolling stock that stops at low platforms and is adapted to the low temperatures of northeastern China, so it is favored by the Harbin Railway Bureau and the Shenyang Railway Bureau. Until April 2014,*** there are 141 sets of CRH5A trains have been shipped, one of them is the 0 high-speed integrated detection train. the CRH5 series design life of 30 years.

CRH high-speed rolling stock life is generally 30 years, the first batch of the introduction of rolling stock is still in use. Maintenance of rolling stock, many easy to wear parts will be frequently updated in the low-level repair, and some other relatively long-life components, but also in the high-level repair repair or replacement. So in fact 30 years is a continuous "renewal" process.

The latest CRH380A braking system developed and produced by China South Locomotive's Nanjing Puzhen Company, with a localization rate of more than 90%, a sustained operating speed of 350 kilometers, a maximum operating speed of 380 kilometers, and a maximum test speed of 486.1 kilometers per hour.

The maintenance of rolling stock, a lot of easy to wear parts will be frequently updated in the low-level repair, and some other relatively long-life components, but also in the high-level repair repair or replacement. So in fact 30 years is a continuous "renewal" process.

At 30 years or so, some parts that are not expected to be replaced during the life cycle (such as the aluminum body) may deteriorate and weaken due to time and use, and may be scrapped at that time.

Of course, whether the train is scrapped or not also depends on the condition of the train being scrapped, and if the train is in good condition, it can still be over-aged after overhaul.
