A 61-m three-car train went through eight stations on a ride of 12.3 km. It made six trips between 8.40 a.m. and 4 p.m. each with more than 300 visitors.
The first test run at the end of 2022 was a trip of nearly nine kilometers with the train stopping at five stations. The second was on April 15 with government officials.
The trains made in Japan have a cockpit at both ends and an aluminum alloy body that is easy to clean.
Briton Tim Shannon is the only driver the metro has. The trains can reach maximum speeds of 110 kph, but during the latest test run, it did not exceed 50 kph.
The three-car train has a capacity of 930 passengers (147 seated and 783 standing).
The two previous test runs carried around 100 passengers each.
"I was very happy to experience the city's first metro line," Le Anh Nguyen (R), 40, of District 1, said.
Mayo Tomita, 30, of Japan said metro trains are similar in her country.
"Hopefully the city will have more metro lines."
Nguyen Trung Hieu, deputy director of Metro Line No.1 Management of HCMC Urban Railway Project Management, said the trial runs, in addition to testing the trains, also help check others such as electrical and mechanical equipment and signals.
On September 2 a test run will be made on the entire line of nearly 20 km before moving to the trial operation phase at the end of this year.
The line is around 95% complete and is being accelerated to quickly complete the remaining work such as installing the equipment and finishing the stations and pedestrian bridges.
