Tuesday 26 November 2019

On 7 November, Train 05301 left Qinghe station in China, marking the first time that an intelligent EMU — the intellectual property rights for which are entirely owned by China — has been formally involved in integrated commissioning and testing on the Beijing-Zhangjiakou HSR.

An official from China Railway Beijing Group Co. Ltd. said that integrated commissioning and testing for intelligent EMUs was implemented mainly between Changping station and Xiahuayuan North station on the Beijing-Zhangjiakou HSR, with a maximum test speed of 350km/h.

The comprehensive inspection train went online on 5 October. Since then, the step-by-step speed-up tests for individual EMUs have been conducted on the up and down lines of the Beijing-Zhangjiakou HSR, with speeds on up and down lines reaching 385 km/h on 20 October. It is reported that China Railway Beijing Group Co. Ltd. began integrated commissioning and testing of Chongli Railway, a branch line of Beijing-Zhangjiakou HSR, on 22 October.

Integrated commissioning and testing of the Beijing-Zhangjiakou HSR covers 17 items and more than 6,000 parameters of various systems such as HSR fixed facilities, mobile equipment, traction power supply, train control, passenger service, etc., involving dozens of operators, construction units, testing units, design units, construction units, supervision units, railway police, etc., with a total of more than 2,000 people participating in various tasks such as testing, accurate adjustment, security, etc.

In order to ensure that the intelligent EMU can be integrated smoothly into online integrated commissioning and testing, the Beijing EMU Depot has deployed special personnel to monitor the running status of the intelligent EMU on a daily basis, collecting indicators and parameters from various links such as departure operation, outbound inspection, on-the-way patrol, inbound maintenance, etc.

Beijing Passenger Depot has transferred personnel from the crew on the Beijing-Shanghai and Beijing-Guangzhou HSRs for business training. It has studied and developed the Beijing-Zhangjiakou HSR operating instructions, supported learning and training on the equipment and facilities of the intelligent EMUs for all personnel, and has added English, minority languages, sign language and other training modules to ensure that the crew is fully prepared.
