Shanghai - Huangshan Train

Currently, over 10 pairs of high speed trains are running between Shanghai and Huangshan with travel time of about 2.5 - 3.5 hours. The  distance is 447 km (278 mi) and a second class seat costs CNY 166.5 - 206.

Besides, coaches are available between the two cities, and it takes about 5.5 - 8 hours for the whole journey. The ticket fare for a seat is CNY 138 - 151, cheaper than the bullet ones, but traveling by coaches may not be that comfortable and coaches are not as punctual as high speed rail.
