I went to the train station and it looks very messy with a lot of traffic and people.
From Beijing:
Train K81 leaves from Beijing daily at 9:30pm, arriving the next morning in Dalian at 7:12am. Tickets for a hard sleeper berth is 231 RMB per way. Coming back from Dalian, take train K83, leaving Dalian at 8:45pm and arriving in Beijing at 6:45am.
