the Padma Bridge Rail Link Project in Bangladesh is an important transportation fulcrum for China's "the Belt and Road " construction, and also an important part of the "Bangladesh-China-India-Myanmar Economic Corridor".

Before the implementation of this Project, there are no BMJs and REJs around the world meeting the requirements of the following three indicators:

①Vertical corner of steel bridge end is 7.5 ‰ and horizontal corner is 10 ‰, much higher than the requirement of 1 ‰ of vertical corner under general circumstances;

②Steel bridge joint expansion capacity is ± 800 mm, which is close to 2.7 times under the ordinary ones;+

③Suitable for the ballastless track.

CRBBG’s success in development and manufacture of BMJ & REJ for the project not only solve the impasse caused by the above three indicators, but also make the products reach the world-class stage.
