The construction of Dongguan Metro Line 1 has reached another key milestone, successful trial runs with powered trains across the entire line. This marks a major step toward its scheduled opening later this year.  

On March 30, after over 10 hours of rigorous testing by more than 200 engineers, the hot-slide test for the second section of Line 1 was successfully completed. This means the entire line has now passed its powered train testing phase, paving the way for final commissioning and full operation. 

What is a hot-slide test?

A hot-slide test is the first powered trial run of a new metro line. Using live electricity from the overhead contact system, the train self-drives while undergoing key performance evaluations, such as: 

• Power supply system checks (contact wire elasticity, insulators, track transitions) 

• Braking and traction tests 

• Communication, signaling, and electromechanical system validation 

• Safety and operational stability assessments
