On November 21, Beijing Urban Engineering Design & Research Institute Co., Ltd (BUEDRI) held and presided the review meeting for the development of 60kg/m No.9 turnout with curved switch rail and monomotor for urban rail transit at Baoji. Experts and representatives from China Railway Engineering Design Consulting Group Co., Ltd, China Railway Signal & Communication Corp., Southwest Jiaotong University, Xi'an Metro Co., Ltd, Chongqing Rai Transit (Group) Co., Ltd, Chengdu Xixin Concrete Co., Ltd, Beijing Xinjie Consulting Co., Ltd and CRBBG, attended the meeting. CRBBG Deputy General Manager Dong Yanlu was present at the meeting.

At the meeting, the experts and representatives attentively listened to the calculation report, manufacturing and switching test report, and inspection report made by the research group, and made a field inspection of the two sets of shop-laid switches. The experts came to an agreement that the 60kg/m No.9 turnout with curved switch rail for urban rail transit adopted monomotor traction mode and linkage external locking system, which reduced the driving system costs and the maintenance work, as well as broke the normal mode of the curved flexible switch rail driven by two sets of point machines, which was a great innovation in the field of urban rail turnout. With CRBBG's proper and advanced manufacturing processes and strict quality control, this turnout was approved to pass the review and could be laid on track for test run.

Deputy G.M. Dong addressed that CRBBG would seriously comb the opinions and suggestions presented by the leaders and experts and put them into effect after the meeting; and keep on stressing on product quality to supply competitive turnouts to the customers.

The 60kg/m No.9 turnout with curved switch rail and monomotor for urban rail transit is a new product co-developed by CRBBG and BUEDRI, fully adopting the mature, reliable and advanced technologies in recent years. During the development, the research group firstly completed theoretical calculation and structural design with softwares such as finite element analysis software ANSYS, actuation force calculation software and 3D modeling software, and conducted switching tests under various working conditions in the shop. Then, with the joint efforts of Turnout R&D Department, Quality Management Department and all workshops, the trial manufacturing and laying of the turnout as well as the tests thereof were accomplished.

It is reported that this turnout is dimensionally exchangeable with the existing turnouts, the successful development of which further enhances CRBBG's competitiveness in the urban rail transit field.
