A total of 11 high-speed electric passenger trains and one inspection train, customized for the Jakarta-Bandung high-speed railway in Indonesia, rolled off the production line in east China's Qingdao City on Friday, according to the China Railway International Co., Ltd.

The trains, designed and manufactured by CRRC Qingdao Sifang Co., Ltd., will be transported to Indonesia.

It marks important progress in the construction of the railway, a landmark project under the Belt and Road Initiative. The delivery of the trains will lay a solid foundation for the high-quality completion of the Jakarta-Bandung high-speed railway according to schedule, said the company.

The 11 passenger trains are known as electric multiple units (EMUs), and the comprehensive inspection train (CIT) is designed to perform railway inspections.

Relying on the advanced technology of China's Fuxing bullet train, the high-speed EMUs and the CIT were designed and manufactured as per the Chinese standards, while being adapted to the local operational environment and line conditions in Indonesia, as well as to the local culture, according to the company. 

Zhang Fangtao, chief designer of the EMUs, said that their bodies have a streamlined appearance, and they have been painted silver and red, symbolizing prosperity.

The EMUs, with a maximum operating speed of 350 km per hour, feature advanced technology, safety, intelligent technology, strong environmental adaptability and distinctive local characteristics, said Zhang.

The EMUs have been designed to match the operating environment along the Jakarta-Bandung high-speed railway, and feature intelligent sensing technology and an earthquake monitoring and early-warning system. The trains are equipped with 2,500 monitoring points for timely detection, early warning and diagnosis of all key systems.

The EMUs have several low-carbon and energy-saving features, including their low-resistance streamlined contours, smooth carriage design and regenerative braking-energy recovery technology. 

Their corrosion-resistant design and advanced protection technology also make the EMUs more resistant to salty mist and ultra-violet aging. 

Zhang said that the EMUs have a large passenger capacity and perfect service functions, and can provide passengers with a comfortable riding experience.

The CIT has been designed to provide comprehensive inspection functions for the Jakarta-Bandung high-speed railway. It's equipped with a diverse array of inspection equipment for track alignment, overhead cables, and communications and signaling systems.

The Jakarta-Bandung high-speed railway connects Jakarta, the Indonesian capital, and Bandung, a famous tourist city in the country. With a total length of 142 km, the line has been designed with a maximum speed of 350 km per hour.
