Can I pick up my train ticket from Hongkong to Guilin at any train station in Hongkong?

For the trip to Guilin, you can only collect it at Hong Kong West Kowloon Station. Other MTR station would not work. The Guilin to Kunming trip, however, need to be collected in a station in mainland. If this two trips are on the same day, you need about 2 hours between for the ticket collection and connection.
