Rail services between Guangzhou and Hong Kong were delayed for 90 minutes yesterday after a mainland train broke down near Dongguan , blocking southbound services.
The incident was the second in 10 days preventing intercity through-train services running smoothly.
Rail services between Guangzhou and Hong Kong were suspended for four hours on December 8 for what authorities said was emergency track work on the mainland section.
Six services - four Guangzhou-bound and two Kowloon-bound - were cancelled.
The Kowloon-Canton Railway Corporation came under fire from disgruntled passengers who were stranded at Hung Hom.
Yesterday, seven services - four Kowloon-bound and three Guangzhou-bound - were delayed because of the train breakdown.
KCRC officials said staff had explained the cause of the delay to passengers at Hung Hom station, but the company did not have a figure for the number of passengers affected.
