The longest one-way railway line in China, with a total length of 4603 km * * 67 hours, passes through 12 province and 1 municipality directly under the central government.

Once, before the arrival of the high-speed rail era, we always took trains with the prefix T, K and Z, and shuttled between major provinces and cities. There is no doubt that the arrival of high-speed rail has ended the era of "formerly slow". However, most ordinary trains still "consciously" pick up and drop off passengers on their own lines, keeping the record of the longest mileage or the longest one-way time.

At present, the longest one-way train line in China is K726, from Kunming to Harbin. Perhaps this 4,603-kilometer train mileage is not the longest in China, but if the one-way trip lasts 67 hours, excluding cross-border trains like K 19, there is no other train line in China that can surpass the one-way trip time of K726. 67 hours, five hours to go, that's three days. The train leaves Kunming at night 19:38, and arrives in Harbin on the afternoon of the fourth day 14:50. All passengers need to spend three nights on the train.

The model is a 25G bus, which runs from southwest to northeast, stopping at 48 stops along the way, so the time is so long. However, the passengers on the K726 train should not feel too uncomfortable, because the scenery along the way can be said to be beautiful. The train passes through Yunnan, Guizhou, Hunan, Jiangxi, Hubei, Anhui, Henan, Shandong, Tianjin, Hebei, Liaoning, Jilin and Heilongjiang provinces, which is 1 municipality directly under the central government.

From Kunming, the "Four Seasons Spring City", to Harbin, the "Ice City and Summer Capital", people are longing for it. In summer, Kunming-Harbin is still a suitable summer route. In winter, friends in the south can feel the scenery in the north in journey to the south in the snow and ice, while friends in the north can take K727 from Harbin for 63 hours and experience this veritable "train to spring". The train makes passengers really feel the climate difference between northeast and southwest.

Kunming has four seasons like spring, with an annual average temperature of 16.5 and a frost-free period of 278 days. Because of the pleasant climate and no severe cold in winter, red-billed gulls are welcomed in Kunming every winter, including migratory birds who come to Kunming for the winter. Therefore, Kunming is often included in the list of popular pension cities. Kunming is a beautiful and charming city, surrounded by mountains on three sides and Dianchi Lake in the south. The lakes and mountains are the first impression of Kunming. There are also flowers that bloom all year round. Whether it is a scenic spot or an ordinary roadside, Kunming is full of places to enjoy flowers.

Harbin is cool in summer, and you can watch ice sculptures and play snow projects in winter. Whether you come to Harbin in summer or winter, you will get different feelings. But no matter when you come, the exotic buildings on the streets of Harbin exude a quiet beauty. The Russian-style city appearance and the beautiful scenery of ice and snow in winter are undoubtedly two important reasons for attracting tourists to Harbin. If these two cities with completely different styles can be connected by a train in one trip, it will be unforgettable for life.

In addition to Kunming and Harbin at both ends of the line, cities along the way are also full of bright spots. For example, Nanchang, a heroic city, Zhuzhou, one of the birthplaces of farming culture in China, Guiyang, the pearl of the plateau, Liupanshui, the cool capital of China, and so on. For those who are not in a hurry, it is a good choice to take K726 to visit the famous mountains and rivers of the motherland!
