北京上海高速鐵路系統有小毛病

Recently the NHK News reported the following:
中国で、先月開業したばかりの北京と上海を結ぶ高速鉄道で、車両の故障などのトラブルが相次いでおり、早くも安全性に課題を抱えています。
中国では先月３０日に北京と上海を５時間足らずで結ぶ高速鉄道が営業運転を開始し、中国政府も、国の科学技術の発展を象徴するものとして、大々的に宣伝してきました。しかし国営の新華社通信によりますと、今月１０日、山東省で強風のため激しく揺れた送電線がショートし、合わせて１９本に遅れが出たほか、１２日は安徽省内で、送電設備の故障によって、一部の列車に遅れが出ました。さらに１３日も、江蘇省内で停車中の車両が突然動かなくなり、急きょ乗客をほかの車両に移す措置をとったものの、２時間半の遅れが出ました。北京・上海間の高速鉄道は、１３００キロを超える長い区間を、着工から３年余りという短期間の工事で完成させた上、日本やドイツから技術提供を受けた結果、異なる規格の車両が入り交じって走ることから、一部の鉄道関係者の間からは、トラブルが起きる可能性を指摘する声が上がっていました。これに対し中国政府は、安全対策は十分とられており、問題はないなどと反論していましたが、開業から２週間でトラブルが相次いだことで早くも安全性に課題を抱えています。

In China the rapid-transit railway, that was just opened last month connecting Beijing and Shanghai, had vehicle breakdown troubles etc. one after another, and already had the safety problem.
In China the rapid-transit railway, opened on the 30th last month connecting Beijing and Shanghai in less than five hours, had begun commercial operations; it had been widely advertised by the Chinese government because it symbolized the development in science and technology of the country. However, according to the government-run Xinhua News Agency, on the 10th this month in Shangtung the power line shook intensely because of the strong wind had caused short-circuit, and delay occurred in 19 flights in total; besides, on the 12th delay happened to one train in Anhui due to the breakdown in the power transmission equipment. In addition, on the 13th, there was a delay up to two and a half hours when the carriage stopped in Chiangsu province suddenly could not move, and measures to hastily transfer passengers to other vehicles were taken. There was voice coming out from some people that were related to the railway, pointing out the possibility that troubles occurred because this rapid-transit railway that went between Shanghai of Beijing and having over 1300 kilo in length, from the start of construction to the completion of construction had taken a short period of three years or more; also the railway had mixed different standards into it because it received technical supports from Japan and Germany. As for the Chinese government, they said that enough security precaution had bee taken for this and refused to admit that there was any problem. Opened only in two weeks, with troubles coming out one after another, it already had safety problem.

Probably the railway system could be run more smoothly after the problems have been identified and the necessary improvements have been carried out.
