The K 1394 train from Jiamusi to Yantai is under the jurisdiction of Harbin Railway Bureau, and the Yantai team of Mudanjiang Passenger Transport Section of Harbin Railway Bureau is responsible for the crew work. It is suggested to call the customer service telephone number of Harbin Railway Bureau at 045 1- 12306, and get the contact information of the crew of the No.04 car K 1394 on October 20th through the Yantai Team of Mudanjiang Passenger Transport Section. Good luck!
