14.60 million trips are expected to be made during the upcoming Labor Day holiday, averaging 2.92 million each day, the country’s railway authority said on Tuesday. The passenger volume will gain by 1.97 million from the same period of last year. Most of the passengers traveling in the Yangtze River Delta will be on sightseeing trips. 107.5 sets of trains will be in service to cope with the demands. This year, the Labor Day holiday will be expanded to four days. The pre-planned one-day break falling on May 1 will be adjusted to a four-day holiday starting from May 1 to May 4 while April 28 and May 5 will be work days. The Labor Day holiday, used to be a seven-day break, was shortened to three days in 2007.
