The train from Chengdu to Lhasa made its debut on July 2, 2006, one day later than the train from Beijing to Lhasa. The train to Lhasa from Chengdu departs every other day at 20:59 from Chengdu Train Station, and arrives at Lhasa Railway Station at 16:50 on the third day after nearly 44 hours covering a distance of 3348 kilometers. Its operational speed is also 120 km/h, 100 km/h over sections laid on permafrost. It costs around RMB1100 for a first-class sleeper berth, about RMB700 for a second-class sleeper berth and half that for a soft seat.
Like each Lhasa-bound train, the train to Lhasa from Chengdu is also especially built for the high altitude environment and equipped with advanced facilities, such as air-conditioning, supercharging system, oxygen supply, altitude display, etc. The train is also tightly sealed so as to firstly keep the inside air pressure normal and secondly prevent passengers from littering. Besides, all the carriages are installed with double-paned windows and ultraviolet filters to protect passengers from ultraviolet radiation. Nowadays, a Chengdu-Lhasa train tour is extremely popular for the breathtakingly unique scenery along the railway from Chengdu to Tibet.
