The new Lok Ma Chau spur line had limited success in relieving the burden on the heavily travelled Lo Wu line during its first weekend, with travellers blaming the poor transport connections on the Shenzhen side.
The Kowloon-Canton Railway Corporation had estimated that 60,000 passengers would travel on the Lok Ma Chau spur line every day within a year, eventually diverting about a quarter of the Lo Wu line's passengers.
According to KCRC figures, the number of passengers who used the new spur line increased from 10,000 on the first day, Wednesday, to slightly more than 20,000 on Thursday and Friday.
About 31,000 people used the new line on Saturday - only about 10 per cent of the traffic in Lo Wu, where 337,000 travellers crossed the border checkpoint.
It was easy to find a seat on a Lok Ma Chau line train yesterday, with some compartments empty.
A KCRC spokeswoman said it would take some time for passengers to become familiar with the new railway service.
