More than 2.5 million passenger trips were undertaken on the Jakarta-Bandung High-speed Railway as of Wednesday, marking the first six months of its operation, according to China Railway International, which oversees the line's operation.

The high-profile high-speed railway commenced operation in Indonesia on October 17 — the first such line in Southeast Asia.

A total of 2.56 million trips were made in the first six months of the line's operation. Over the period, a total of 7,050 train trips were operated, covering a distance of over 1.26 million kilometers.

The number of the daily trips has increased from 17 services per day at the beginning of the line's operation to the peak of 52 a day, with a peak day handling 21,537 passenger trips.

The 142-kilometer Jakarta-Bandung High-Speed Railway, which has a designated maximum speed of 350 kilometers per hour, cuts travel time between the Indonesian capital and the popular tourist destination from 3 hours 30 minutes to 40 minutes.

The project was the first overseas venture to rely wholly on Chinese railway systems, technology and components.
