--File--A CRH (China Railway High-speed) trains runs on the Shanghai-Nanjing High-speed Railway in Nanjing city, east Chinas Jiangsu province, 9 March 2011. Chinas expanding high speed rail network, which is considered the countrys symbol of modernization, is now coming under scrutiny over costs and because of concerns that builders ignored safety standards in the quest to build faster trains in record time. The trouble for fast moving rail project began in February with the firing and detention of the countrys top railway official for being involved in corruption. Recently, the new leadership at the Railways Ministry announced that to enhance safety, the top speed of all trains was being decreased from about 218 mph to 186mph. It said so without elaborating that the ministry called the safety situation severe and said it was launching safety checks along the entire network of tracks, The Washington Post reports. Recent revelations have raised questions about the projects future and have also highlighted many of the countrys interlinking problems, such as top-level corruption, concerns about construction quality and a lack of public input into the planning of large-scale projects.
