I have double checked and I reconfirm that taking a train from Beijing to Hong Kong, under 144 hour visa free transit, is not possible. Formally, you would be able to see something like this as a possibility and even more, such a possibility is still listed in Timatic, however, those conventional trains that were departing from Beijing West Railway Station toward Hong Kong Hung Hom station are now gone. Simply speaking, currently the trains departing from Beijing toward Hong Kong are no more treated in Beijing as if they were exiting mainland China and that formally means that you would be traveling all the way until Hong Kong West Kowloon train station as a passenger in domestic transport and that is something that is not allowed.
Several years ago, when you were boarding the train in Beijing, you were crossing the exit immigration right at Beijing West Railway Station as if you were leaving mainland China. So, your later travel was, de jure, outside mainland China regardless of the fact that you were traveling through its territory for many hours after that. Today the Hong Kong bound trains are purely domestic and they become "international" only at Hong Kong West Kowloon station in Hong Kong where both mainland Chinese and Hong Kong immigration facilities are located "under one roof". Trust me, you cannot do that and I hope you will trust me. By the way, diplomatic missions are not the address for this subject because they do not have jurisdiction over the details that are treated by the Chinese immigration authorities. Totally different ministries. Please, buy your plane ticket out of Beijing toward Hong Kong and enjoy your time. Do not allow to be rejected. Have a nice journey.
