The Mid-Autumn Festival (中秋节) and Chinese National Day (国庆节) are two of the busiest travel seasons, and due to still-warm weather conditions, a fair number of passengers from abroad are likely to be on the move.
Advance booking has already begun beginning today (29 July 2015), with the first tickets being made available already at 08:00 from Beijing West (Beijingxi) Railway Station. These are for the first day of the Mid-Autumn Festival break, which is 26 September 2015. This year, the three-day break (which would have lasted until 28 September 2015) will be cut short by one day, with the third day being given to 11 October 2015.
Tickets for the first day of Chinese National Day, 01 October 2015, will be made available on 03 August 2015, although most will choose to travel a day earlier, so that tickets for 30 September 2015 will be ready for sales on 02 August 2015.
The next long weekend, however, will be from 03 September 2015 through to 05 September 2015, when China commemorates 70 years since the surrender of Japan, thus ending World War II.
There will be some temporary restrictions for trips to northeastern China made after late August 2015. This is due to the opening of new lines (including a new express line to Dandong, just on the border with north Korea) and fine-tuning of timetables for that part of China.
The earliest passengers can buy tickets from regular counters will be on 31 July 2015 for the first day of the Mid-Autumn Festival, 04 August 2015 for 30 September 2015, and 05 August 2015 for the start of Chinese National Day.
