拍攝日期:2022年5月17日
拍攝區間:金鐘7號月台至上水1號月台
拍攝列車:MTR R-train TS4 (D012車廂)
拍攝車次:JH0289(由GPS測得之最高車速為每小時117公里,畢架山隧道的最高車速為每小時120公里)
牽引動力:三菱 Si-IGBT(IPM) VVVF 逆變器 + 三菱 MB-5153-A 三相交流電動機
影片簡介:本片攝於東鐵過海後的首個非下雨天,列車採用正常減速率(0.8m/s/s)進入車站。雖然本班列車與上一班列車(JH0287)的間距只有1分31秒至2分29秒,但受惠於TGMT移動閉塞信號系統,儘管前面的列車尚未完全離開月台,本班列車亦能以一定的車速進入月台。
* 註1:全球衛星定位系統 (GPS) 於較密封的空間下準確度會相當低,因此未能提供行駛該等路段的測量車速或無法顯示準確的車速。
* 註2:畢架山隧道及過海鐵路段的車速以多組信號燈及緊急逃生門的通過時間進行精密計算。

Section: Admiralty to Sheung Shui
Trainset: MTR R-train TS4 (Compartment D012)
Trip Number: JH0289 (Maximum GPS measured speed was about 117 km/h, the actual maximum speed inside Beacon Hill tunnel was 120 km/h)
Traction: Mitsubishi Si-IGBT(IPM) VVVF Inverter + Mitsubishi MB-5153-A Induction Motor
Description: The video was taken on the first non-rainy day after the East Rail Cross Harbour Extension commenced service, normal brake rates (0.8 m/s/s) were applied when the trains are approaching the platforms. Although the headway of this train from the previous train (JH0287) was only about 91 seconds at minimum, thanks to TGMT moving block signalling system, the train could enter the next platform at a certain speed despite the previous train had not yet departed completely away.
* Note 1: The accuracy of measurement by Global Positioning System (GPS) is rather low in relatively enclosed space, thus the measured speed are not taken when the train was travelling in the corresponding section.
* Note 2: The travelling speed within Beacon Hill Tunnel and Cross Harbour tunnels were precisely calculated by the passing time of signal lights and emergency cross passage doors.
