China Railways CRH2

The CRH2 is one of the high-speed train models in China. Originally, the CRH2 was a modified E2-1000 Series Shinkansen design from Japan with the license purchased from a consortium formed of Kawasaki Heavy Industries, Mitsubishi Electric Corporation, and Hitachi, and represents the second Shinkansen train model to be exported, the other being the 700T series for Taiwan High Speed Rail.

In 2004, the Ministry of Railway in China purchased an initial 60 sets of the train from Kawasaki Heavy Industries with a maximum speed of . However, the newer versions of the CRH2 are not related to the E2-1000 Series despite having the same exterior. The vice-chief engineer at CSR Sifang Locomotive and Rolling Stock stated that the newer CRH2 trains are their design with all of the main engineering components produced in their company.[1]

In fact, according to Kawasaki Heavy Industries, they confirmed that they are no longer working with CSR Sifang Locomotive and Rolling Stock and the last deal struck with Sifang was in 2004 for the production of 60 modified E2-1000 Series. According to the vice-chief engineer of Sifang, "the shape maybe the same but [inside] it's completely different." A Japanese official affiliated with the 2004 deal stated that "they could not imagine that the catch-up would be so fast." Starting from 2008, all CRH2 trains were designed and manufactured under key technology developments made by Sifang without Kawasaki. In fact, the vice-chief engineer of Sifang stated that their latest models "have nothing at all to do with Shinkansen" except that they share a similar exterior shape.

History

CRH2A

[[File:JRE Shinkansen E2 Series-0 and 1000.jpg|250px|thumb|The CHR2 evolved from the E2 Series Shinkansen On October 20, 2004, the Ministry of Railway in China ordered 60 sets of CRH2A trains from Kawasaki Heavy Industries in Japan. Along with 60 sets of Bombardier's Regina-based CRH1A, and 40 sets of Alstom's Pendolino-based CRH5A, these train sets are consider as first batch of CRH trains.

Each of the CRH2A set consists of 8 cars. The first 3 sets (CRH2-001A - CRH2-003A) were built in Japan, the next 6 sets (CRH2-004A - CRH2-009A) were delivered in complete knock down form and assembled by CSR Sifang Locomotive and Rolling Stock. The remaining 51 sets (CRH2-010A - CRH2-060A) were built by Sifang through technology transfer from Japan.

The first train arrived at Qingdao port on March 8, 2006 with little fanfare, and was not even publicized in China. These trains have a maximum operation speed of and started providing high-speed train service from April 18, 2007, the date of the sixth national railway speed-up.

According to Chinese and Japanese media, CRH2A trains started test trials ahead of commercial operation on the Shanghai-Hangzhou and Shanghai-Nanjing lines on January 28, 2007.

On September 14, 2010, the Chinese MOR ordered additional 40 sets of CRH2A trains (CRH2-151A - CRH2-190A) from CSR Sifang.

CRH2B

In November 2007, the Ministry of Railway in China ordered 10 CRH2 sets with 16 cars per set (8M8T). These trains have been given designations CRH2B (CRH2-111B - CRH2-120B). Each CRH2B has three 1st seating cars (ZY), twelve 2nd seating cars(ZE), and one dining car(CA). Designed maximum operation speed is with a power of .

The first units were delivered on June 29, 2008,[2][3] and came into service on Hefei-Nanjing PDL on August 1, 2008.[4]

CRH2C

After the induction of the modified E2-1000 Series, Sifang built its own CRH2 with a maximum safe operating speed of . The original train sets imported from Kawasaki had a maximum safe operating speed of .

During June 2005 and September 2005, The Chinese Ministry of Railways launched bidding for High speed trains with a top speed over . Along with Siemens's Velaro-based CRH3C, CSR Sifang bid 60 sets of CRH2C, includes 30 sets of CRH2C stage one with a top speed of , and 30 sets of CRH2C stage two with a top speed of .

In development and research of the high speed train, The CRH2-300 project was launched by Chinese MOR and CSR. In 2006 the China Development Bank provided CNY 15 billion developmental financial loans to CSR Group for the projects of high speed trains.[5] Over 50 academics, 150,000 technicians, 600 contractors were involved in the project.[6]

CRH2C stage one

CRH2C Stage one is a modified version of CRH2. It has a maximum operating speed up to by replacing two intermediate trailer cars with motorized cars. Equipped with an array of the state-of-the-art technologies, including aluminum alloy body with a reduced weight, high speed turntable, high speed pantograph, and optic-fiber based integrated control system.[7]

Chinese MOR ordered 30 sets of CRH2C stage one, name code CRH2-061C - CRH2-090C. The first set, CRH2-061C was unveiled on December 22, 2007.[8][9]

During the test on April 22, 2008, CRH2-061C reached a top speed of over on Beijing-Tianjin high-speed rail.[10]

During the test on December 11, 2009, CRH2-061C reached a top speed of on Zhengzhou-Xi'an high-speed rail.[11]

Together with CRH3C, the CRH2C stage one first came into service on Beijing-Tianjin Intercity high-speed rail on August 1, 2008, and all CRH2C stage one trains have been replaced by CRH3C in April, 2009. Currently, most of these trains are serving on the Shanghai-Nanjing high speed rail.

CRH2C stage two

CRH2C Stage two is the "re-design" version of the CRH2. Some of the details, like the aluminum body structure, noise reduction technology & reduction technique, draw on the CRH3C. According to CSR Sifang, the improvements include the following aspects:

  • The axle weight of the bogie increased from , to provent tremble of the train body at a higher speed,[6] the gear ratio has been optimized from 3.036 to 2.379, the critical instability speed is .
  • The thermal capacity of the bogie has been increased,which satisfied the continuous operation at
  • With the YQ-365 type AC traction motor. It has a maximum operating speed up to with a power of .
  • The rigidity of the car body has been increased to lower the noise and vibration.
  • Optimized car body and window design for better air tightness and strength.
  • Added pressure protection system to avoid pressure fluctuation in the compartment and improvement of comfort.
  • Optimized design of the roof antenna,exterior windscreen and windows for a lower air resistance.[12]

Chinese MOR ordered 30 sets of CRH2C stage two, name code CRH2-091C - CRH2-110C and CRH2-141C - CRH2-150C. The first set, CRH2-091C was unveiled in January 2010 and came into service on Zhengzhou-Xi'an high-speed rail in February, 2010.[13]

CRH2E

In November and December 2007, the Ministry of Railway in China ordered 20 CRH2 sleeper trains with 16 cars per set (8M8T). These trains are modified CRH2Bs, and have been given designations CRH2E (numbered CRH2-121E - CRH2-140E). Each CRH2E has thirteen 1st class sleeping cars (WR), two 2nd class seating cars (ZE), and one dining car (CA). Designed maximum operation speed is 250 km/h (155 mph) with a power of 9600 kW.

The first batch of CRH2E, CRH2-121E - CRH2-126E, came into service on Beijing-Shanghai railway on December 21, 2008.[2][14] On 23 July 2011, one sleeper (CRH2-139E) was derailed in the 2011 Wenzhou train collision, together with CRH1-046B.

CRH2-350

In 2008, the Chinese MOR & CSR launched CRH2-350 project, the main purpose is to develop new-generation of high speed trains with maximum operation speed of . CRH2 is one of the fundamental platforms of the new trains, which is designated as CRH380A. On September 28, 2010, one of the CRH380A test sets hit while testing on the line between Shanghai and Hangzhou, capital of the province of Zhejiang, set a new record for rail speed.[15][16]

Formation

At the time of the sixth national railway speed-up, at least 37 CRH2A sets had been delivered by Kawasaki and Sifang.[17] In 2008, all 60 CRH2A sets had been delivered by Kawasaki. The post-2008 production model of the CRH2 are designed and made solely by Sifang with a maximum safe operation speed of .[1]
