CHONGQING (CQNEWS) -- According to the Chongqing Rail Transit Line 4 Construction Operation Co., Led., the phase I and phase II of Chongqing Rail Transit Line 4 have finished debugging and entered the stage of full-map test run, which means the phase II of CRT Line 4 has entered the final stage of test run without carrying passengers.

To make sure the safe and sound full-map debugging, CRT Line 4 Construction Operation Co., Ltd. has organized the bid packages and the contractor has completed the technical and safety disclosures as well as the propagation and implementation of an emergency response plan, making an overall plan for the test - the contractor has taken a measurement of the train’s operation time and dwelling time, reentrant time, and the time of the train exiting and entering a yard; verify the safety of the facilities and equipment along the line; carry out the test run of the phase I and II project in line with the formal standard.

To date, the phase I and phase II of CRT Line 4 have entered the stage of a full-map test run. With a complete turnround period of 140 minutes, the traffic routing stretches from Min’an Avenue Station to Huangling Station. In addition, the passenger-carrying section runs from Min’an Avenue Station to Tangjiatuo Station. After clearing passengers at Tangjiatuo Station, down trains will run to Huangling Station without passengers and up trains will carry passengers again after Tangjiatuo Station.

What else can we learn from the news?

What is “a full-map test run”?

After the phase II was put into operation, it will, combined with the phase I, receive a full-map test rum. Before the train is officially put into use with passengers carried, a full-map test run with the extant line is a required routine. During the test run, the extant phase I of CRT Line 4 from Min’an Avenue Station to Tangjiatuo Station will still run with passengers carried, while the phase II from Tieshanping Station to Huangling Station will be in the test run without passengers.
