Recently, with the approval of the Chengdu Municipal People’s Government, the much-anticipated Chengdu Metro Line 18 will officially open its initial operation. It is the first urban rail transit line in the country that has the reserved maximum speed of 160 kilometers per hour. It is also the fastest urban express line in the country to enter the central city. 

Chengdu Rail Transit Line 18 is an important measure to implement the construction of the Chengdu-Chongqing Double City Economic Circle and Chengdu’s “East Advance” strategy, It is also the first rail transit line constructed and operated in the PPP mode in Chengdu. After the opening of Line 18, the operating mileage of Chengdu rail transit is nearly 400 kilometers, which will improve the network of Chengdu rail transit, greatly alleviate the traffic pressure on the north-south development axis of the city, and further give full play to the rapid transportation service function of rail transit after the network is formed, to meet the needs of citizens for efficient and convenient travel.

In order to meet the needs of on-site sound reinforcement, the engineers adopted TRS. G20 dual 10-inch line array speakers.
