8月15日7時(shí)50分，牡佳高鐵聯(lián)調(diào)聯(lián)試現(xiàn)場(chǎng)首組CR400BF-G型復(fù)興號(hào)高寒動(dòng)車組從牡丹江站緩緩駛出，這是復(fù)興號(hào)高寒動(dòng)車組首次參與牡佳高鐵（high-speed railway linking Mudanjiang and Jiamusi）聯(lián)調(diào)聯(lián)試。

It was the first time a Fuxing bullet train has run on China's easternmost high-speed line, which is located in an extremely cold region.
這是復(fù)興號(hào)高寒動(dòng)車組首次在中國(guó)最東端高寒高鐵線路試跑。

據(jù)介紹，CR400BF-G型復(fù)興號(hào)高寒動(dòng)車組系在復(fù)興號(hào)動(dòng)車組“金鳳凰”的基礎(chǔ)上進(jìn)行了高寒適應(yīng)性技術(shù)提升。

The CR400BF-G Fuxing bullet trains are designed to withstand the climate in extremely cold areas that may be hit by blizzards and temperatures as low as -40 C. Designers chose materials with better airtightness for the equipment compartment, which can keep out the snow and cold air.
CR400BF-G型復(fù)興號(hào)高寒動(dòng)車組具有耐高寒、抗風(fēng)雪等特點(diǎn)，能夠在-40℃的天氣下運(yùn)行。設(shè)計(jì)人員為設(shè)備間選擇了密封性更好的材料，達(dá)到防雪、低溫防凍的目的。

Designers also installed sanding gear in the train, which may help increase traction and prevent the wheels slipping in snowy weather.
同時(shí)，設(shè)計(jì)人員還在動(dòng)車組上安裝了撒砂裝置，能夠在降雪天氣增加阻力，防止車輪打滑。

牡佳高鐵位于黑龍江省東部地區(qū)，沿線經(jīng)過(guò)牡丹江市、雞西市、七臺(tái)河市、雙鴨山市、佳木斯市等地。

Construction of the Mudanjiang-Jiamusi high-speed railway started in November 2016. The 371-kilometer line, designed for trains running at up to 250 kilometers per hour, will cut travel time between Mudanjiang and Jiamusi from seven to two hours.
牡佳高鐵于2016年11月開(kāi)工，全長(zhǎng)371公里，設(shè)計(jì)時(shí)速250公里。通車后，牡丹江到佳木斯的通行時(shí)間將從7小時(shí)縮短為2小時(shí)。

鐵路部門(mén)介紹，

Since June 10, different types of bullet trains have been put into use in test runs to ensure the line can operate safely, the group said.
自6月10日以來(lái)，已有不同型號(hào)的動(dòng)車組在該線路試運(yùn)行，以確保線路安全運(yùn)營(yíng)。

The dynamic detection and debugging of rail track, communication, signal, power supply, disaster monitoring and other systems has been completed and the whole system has been optimized, the group said.
軌道、通信、信號(hào)、供電、災(zāi)害監(jiān)測(cè)等系統(tǒng)的動(dòng)態(tài)檢測(cè)和調(diào)試已完成，整體系統(tǒng)功能得到了優(yōu)化。

鐵路部門(mén)介紹，牡佳高鐵聯(lián)調(diào)聯(lián)試結(jié)束后，將轉(zhuǎn)入運(yùn)行試驗(yàn)階段（trial operation），為后續(xù)全線開(kāi)通運(yùn)營(yíng)奠定基礎(chǔ)。
