In 2011 , the concerned department of former Ministry of Railways authorized MBEC to revise Regulations for High Strength Bolts Construction of Railway Steel Bridge ( TBJ 214-92 ) which was issued in 1992 . On the basis of the investigation and research on high strength bolts connection of several large railway steel bridges, and in view of the development of modern steel bridge construction, the research group reviewed the provisions of the current railway standards and conducted extensive investigations into such issues as manufacturing process, delayed fracture, quality inspection, associated standards, the joint with combined bolts and welds, tightening methods, tools and equipment involved in the construction of railway steel bridge to benefit the revision and application.
