(First time China train traveler)Looking for advice for a trip to Yunan during National Day holiday. I plan to take a train from Cili (in Hunan) to Huaihua (also in Hunan) and meet up with friends on the train to Kunming in Huaihua. I am concerned as the train from Cili to Huaihua arrives at 14:05 and the train to Kunming (which my friends will be on) leaves Huaihua at 14:47. Is this cutting it too close? How reliable are the train schedules? Will the station possibly to crowded to maneuver to a new train in just 30mins?

Thanks in advance for the help!!
