Hello,
I am trying to find out if it is possible to travel from the Vietnamese border (Hekou) to Kunming in China by train? I have looked at a plan of the Chinese rail system which shows it as having a station, but cannot find any details of trains for it? Does this mean that the journey is only accessible by bus?

I am planning to cross the border on the 3rd of May. Any information you can give will be very useful.
Thanks
