DEMS attends 12th World Congress on High-Speed Rail
The Director of Electrical and Mechanical Services (DEMS), Mr Poon Kwok-ying, led a delegation from the Electrical and Mechanical Services Department (EMSD) to attend the 12th World Congress on High-Speed Rail, which was held from July 8 to 11 in Beijing.
The Congress, under the theme "High Speed Rail: Innovation and Development for a Better Life", was co-hosted by International Union of Railways and China State Railway Group Co. Ltd. The opening ceremony was officiated by Vice Premier of the State Council Mr Zhang Guoqing, together with other distinguished guests. The Congress invited over 2 000 participants, including world-leading railway experts, business leaders, government officials, and representatives of international organisations. The event aimed to strengthen the collaboration and development of the high speed railway (HSR) industry in the world.
By participating the Congress, the EMSD delegation enhanced the professional knowledge sharing and exchange with national and international railway stakeholders. Through the technical visit of the China Academy of Railway Sciences, the EMSD delegation kept abreast of the latest development in design and construction technology of the two types of "Fuxing" CR450AF and CR450BF Mainland HSR trains with maximum speed at 450 km/hr, and also witnessed China's HSR remarkable achievements in safety, speed, innovation and technology.
Mr Poon took this opportunity to invite the stakeholders to attend the International Railway Safety Council 2025 conference, which will be held in Hong Kong from November 25 to 30. The Conference, under the theme "Advancing Railway Safety through Innovations and Collaborations", will be jointly organised by the National Railway Administration, the EMSD and the MTR Corporation. The delegates around the world will carry out in-depth exchanges on the issue of global railway safety development and appreciate the rapid development and innovative accomplishment of China's railway in recent years through technical visit.

An unseasonably mild December
With the northeast monsoon over southern China generally weaker than normal for most of the time in the month, December 2025 was much warmer than usual in Hong Kong. The monthly mean maximum temperature of 22.4 degrees, monthly mean temperature of 20.2 degrees and monthly mean minimum temperature of 18.4 degrees were 2.0 degrees, 2.0 degrees and 2.2 degrees above their corresponding normals, and all of them were the second highest on record for December. This was also the first time that no Cold Weather Warning was in force in November and December in a year since the Cold Weather Warning System commenced operation in 1999. The month was also drier than usual with a total rainfall of 6.5 millimetres, only about 23 per cent of the normal of 28.8 millimetres. The annual total rainfall of 2 558.7 millimetres was about 5 per cent above the annual normal of 2 431.2 millimetres.
With a band of clouds covering the coast of Guangdong, the weather of Hong Kong was mainly cloudy with one or two rain patches on the first four days of the month. Under the influence of a dry northeast monsoon, the weather turned generally fine and dry on December 5 and remained so on the following four days. With the return of a cloud band, it turned mainly cloudy with one or two rain patches on December 10 and the next morning. It turned generally fine during the day on December 11 as the clouds thinned out. With plenty of sunshine, the maximum temperature at the Observatory rose to 26.0 degrees that afternoon, the highest of the month. A fresh to strong easterly airstream affected the coast of Guangdong the next day. Locally, the weather remained mainly fine and dry.
A cold front moved across the coast of Guangdong on the late afternoon of December 13. Under the influence of its associated strong northeast monsoon, winds strengthened from the north and temperatures fell progressively. It was rather cool on the mornings of the next two days. Additionally, while one or two rain patches occurred on December 13 under the influence of a broad band of clouds, the weather turned generally fine on the night of December 14 under the influence of a dry northeast monsoon and remained so on the next three days. It was also very dry on December 14 and 15, with the relative humidity over most parts of the territory staying around 30 to 40 per cent during the day. With the return of a broad band of clouds, the weather became cloudier with one or two rain patches later on December 18 and the next day. As the cloud band thinned out, the weather turned generally fine and dry during the day on December 20.
Under the influence of a fresh to strong northeast monsoon, it was windier on the following two days. While it was fine and dry on December 21, the weather turned mainly cloudy on December 22 due to the approach of a cloud band and remained so on the following four days. While there were one or two rain patches on the morning of December 25, with a replenishment of the northeast monsoon reaching the coast of Guangdong that morning, the local weather became dry and cool that day. It remained dry with rather cool mornings on the following two days, with the temperature at the Observatory falling to a minimum of 13.8 degrees on the morning of December 27, the lowest of the month. Under the influence of the dry northeast monsoon, the local weather turned mainly fine from December 27 to 29. With the moderation of the northeast monsoon, winds subsided on December 30, with visibility falling below 5 000 metres over parts of the territory that morning. An easterly airstream brought cloudier weather on the last day of the month.
