what is the difference between "huangshan" station and "the north" station?

The main station is located at No. 33 Qianyuan North Road, the downtown area of the city, which is about 36 miles from the attraction. The north railway station is also far from the scenic area, about 30 miles.

If you are going to take a train from Beijing, you have no choice. All the train will stop at North Railway Station. But don’t worry, from the north railway station, there are direct buses going to the Tankou (The south gate of the scenic area). The bus fare is CNY20 per person.

Thank you for your reply!
The question is...what is the schedules of the buses? what time does it leave?
I want to make sure that I will catch the last bus...

Thank you!

Well, the last bus leaves from HS Station for the mount around 17:30, while the last one leaves at 18:30. Hope you can catch it. And the latter is for high-speed trains by the way.
